Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.
A homologous family of regulatory enzymes that are structurally related to the protein silent mating type information regulator 2 (Sir2) found in Saccharomyces cerevisiae. Sirtuins contain a central catalytic core region which binds NAD. Several of the sirtuins utilize NAD to deacetylate proteins such as HISTONES and are categorized as GROUP III HISTONE DEACETYLASES. Several other sirtuin members utilize NAD to transfer ADP-RIBOSE to proteins and are categorized as MONO ADP-RIBOSE TRANSFERASES, while a third group of sirtuins appears to have both deacetylase and ADP ribose transferase activities.
DNA Restriction Enzymes
Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another. EC 3.21.1.
A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
Polymorphism, Restriction Fragment Length
Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
Physical Conditioning, Animal
A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
Surgical procedure in which the STOMACH is transected high on the body. The resulting small proximal gastric pouch is joined to any parts of the SMALL INTESTINE by an end-to-side SURGICAL ANASTOMOSIS, depending on the amounts of intestinal surface being bypasses. This procedure is used frequently in the treatment of MORBID OBESITY by limiting the size of functional STOMACH, food intake, and food absorption.
Carbohydrates present in food comprising digestible sugars and starches and indigestible cellulose and other dietary fibers. The former are the major source of energy. The sugars are in beet and cane sugar, fruits, honey, sweet corn, corn syrup, milk and milk products, etc.; the starches are in cereal grains, legumes (FABACEAE), tubers, etc. (From Claudio & Lagua, Nutrition and Diet Therapy Dictionary, 3d ed, p32, p277)
A status with BODY WEIGHT that is above certain standard of acceptable or desirable weight. In the scale of BODY MASS INDEX, overweight is defined as having a BMI of 25.0-29.9 kg/m2. Overweight may or may not be due to increases in body fat (ADIPOSE TISSUE), hence overweight does not equal "over fat".
Deoxyribonucleases, Type II Site-Specific
Enzyme systems containing a single subunit and requiring only magnesium for endonucleolytic activity. The corresponding modification methylases are separate enzymes. The systems recognize specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. EC 184.108.40.206.
Heat production, or its measurement, of an organism at the lowest level of cell chemistry in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the heat production from an analysis of the end products of oxidation within the organism or from the amount of oxygen utilized.
A 28-amino acid, acylated, orexigenic peptide that is a ligand for GROWTH HORMONE SECRETAGOGUE RECEPTORS. Ghrelin is widely expressed but primarily in the stomach in the adults. Ghrelin acts centrally to stimulate growth hormone secretion and food intake, and peripherally to regulate energy homeostasis. Its large precursor protein, known as appetite-regulating hormone or motilin-related peptide, contains ghrelin and obestatin.
AMP-Activated Protein Kinases
Intracellular signaling protein kinases that play a signaling role in the regulation of cellular energy metabolism. Their activity largely depends upon the concentration of cellular AMP which is increased under conditions of low energy or metabolic stress. AMP-activated protein kinases modify enzymes involved in LIPID METABOLISM, which in turn provide substrates needed to convert AMP into ATP.
Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed)
Gene Expression Regulation
Body Mass Index
An indicator of body density as determined by the relationship of BODY WEIGHT to BODY HEIGHT. BMI=weight (kg)/height squared (m2). BMI correlates with body fat (ADIPOSE TISSUE). Their relationship varies with age and gender. For adults, BMI falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese). (National Center for Health Statistics, Centers for Disease Control and Prevention)
Insulin-Like Growth Factor I
A well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on GROWTH HORMONE. It is believed to be mainly active in adults in contrast to INSULIN-LIKE GROWTH FACTOR II, which is a major fetal growth factor.
The effect of dietary restriction during development in utero on the frequency of spontaneous somatic mutations. (1/1289)Caloric or dietary restriction is known to be protective against cancer in humans and in mice but the mechanism is uncertain. Given that somatic mutations are important in carcinogenesis, dietary restriction may act by changing mutation rates. Indeed, previous studies have shown that reductions in caloric intake during development or in adult life make mice less susceptible to high doses of mutagens. In these studies there have been hints that the spontaneous mutant frequency may also be reduced, but no significant decrease has been observed save in one study of very old mice. Since the spontaneous mutant frequency is already low, reductions from this level require the use of much larger sample sizes than usual and larger than those used in the previous studies. As pre-existing mutations cannot be eliminated, it is necessary to reduce the dietary intake over a period of time when a substantial proportion of spontaneous mutations arise in order to see an effect. To overcome such problems, the dietary restriction in this study was applied during the time of the highest mutation rate, early development, and many more than the usual number of animals were studied. SWR female mice were crossed with Muta(TM)Mouse males to obtain F(1) progeny for analysis of mutant frequency. At conception, the dams were put into two groups, one that was fed ad libitum and another which was fed 80% of the ad libitum diet. Pups were killed at birth, DNA was extracted from the whole animal and used to measure the mutant frequencies of the mice at the cII locus. Although the weights of the pups from dams whose diet was restricted were significantly less than those of the ad libitum mice (P = 0.003), the litter sizes in the two groups were approximately the same and did not differ significantly (P = 0.13). There was no significant difference in the mutant frequencies in the dietarily restricted and ad libitum groups (P = 0.43). In addition, there was no significant correlation between the weights of the pups and their mutant frequency in either the ad libitum or dietarily restricted groups (r(2) = 0.14 and r(2) = 0.024). No difference was observed in mutant frequency between the ad libitum and dietarily restricted mice from litters of the same size (P = 0.61). These results indicate that the protective effect of dietary restriction on cancer rates is not mediated by an alteration in the spontaneous rate of mutation but rather by another mechanism, such as its effect on induced mutation.

Evidence that the decrease in liver glycogen is associated with the exercise-induced increase in IGFBP-1. (2/1289)The purpose of the present study was to test the hypothesis that the exercise-induced increase in insulin-like growth factor binding protein (IGFBP)-1 is not always linked to a decrease in blood glucose level and to examine whether the decreasing levels of liver glycogen during exercise may be associated with the increase in IGFBP-1. Three groups of rats were submitted to a 70-min treadmill exercise. One group of rats was fed normally, and the two other groups had their food intake restricted by 50% (50% fast) the night before the experiment. One of these two 50% fasted groups of rats was infused (intravenously) with glucose throughout exercise to maintain euglycemia. Exercise in noninfused 50% fasted rats, compared with the normally fed rats, resulted in significantly lower blood glucose (minute 70) and insulin levels, significantly lower liver glycogen content, no change in IGF-I, and significantly higher increases in free fatty acid, glycerol, beta-hydroxybutyrate, and IGFBP-1. Maintenance of euglycemia during exercise in glucose-infused 50% fasted rats reduced to a large extent the decrease in insulin levels but only slightly attenuated the lipid response and the IGFBP-1 response seen in noninfused 50% fasted rats. Comparisons of all individual liver glycogen and IGFBP-1 values revealed that liver glycogen values were highly (P < 0.001) predictive of the IGFBP-1 response during exercise (R = 0.564). The present results indicate that the IGFBP-1 response during exercise is not always linked to a decrease in plasma glucose and suggest that the increase in IGFBP-1 during exercise may be related to the decrease in liver glycogen content.

Upregulated promitogenic signaling via cytokines and growth factors: potential mechanism of robust liver tissue repair in calorie-restricted rats upon toxic challenge. (3/1289)Previously we reported that moderate calorie restriction or diet restriction (DR, calories reduced by 35% for 21 days) in male Sprague-Dawley rats protects from a lethal dose of thioacetamide (TA). DR rats had 70% survival compared with 10% in rats fed ad libitum (AL) because of timely and adequate compensatory liver cell division and tissue repair in the DR rats. Further investigation of the mechanisms indicate that enhanced promitogenic signaling plays a critical role in this stimulated tissue repair. Expression of stimulators of promitogenic signaling interleukin-6 (IL-6), inducible nitric oxide synthase (iNOS), hepatocyte growth factor (HGF), transforming growth factor-alpha (TGF-alpha), and epidermal growth factor receptor (EGFR) were studied during liver tissue repair after TA-induced liver injury. Plasma IL-6 was significantly higher in the DR rats, with 6-fold higher expression at 48 h after TA administration. Immunohistochemical localization revealed significantly higher expression of IL-6 in the hepatic sinusoidal endothelium of DR rats. Expression of TGF-alpha and HGF was consistently higher in the livers of DR rats from 36 to 72 h. EGFR, which serves as a receptor for TGF-alpha, was higher in DR rats before TA administration and remained higher till 48 h after TA intoxication. DR-induced 2-fold increase in hepatic iNOS activity is consistent with early cell division in DR rats after TA challenge. These data suggest that the reason behind the higher liver tissue repair after TA-induced hepatotoxicity in DR rats is timely and higher expression of the growth stimulatory cytokines and growth factors. It appears that the physiological effects of DR make the liver cells vigilant and prime the liver tissue promptly for liver regeneration through promitogenic signaling upon toxic challenge. (+info)
Chaperones come of age. (4/1289)Chaperone function plays a key role in repairing proteotoxic damage, in the maintenance of cell architecture, and in cell survival. Here, we summarize our current knowledge about changes in chaperone expression and function in the aging process, as well as their involvement in longevity and cellular senescence. (+info)
High osmolarity extends life span in Saccharomyces cerevisiae by a mechanism related to calorie restriction. (5/1289)Calorie restriction (CR) extends life span in many different organisms, including mammals. We describe here a novel pathway that extends the life span of Saccharomyces cerevisiae mother cells but does not involve a reduction in caloric content of the media, i.e., there is growth of yeast cells in the presence of a high concentration of external osmolytes. Like CR, this longevity-promoting response to high osmolarity requires SIR2, suggesting a common mechanism of life span regulation. Genetic and microarray analysis indicates that high osmolarity extends the life span by activating Hog1p, leading to an increase in the biosynthesis of glycerol from glycolytic intermediates. This metabolic shift likely increases NAD levels, thereby activating Sir2p and promoting longevity. (+info)
Effect of low protein and low energy diet on physiological status and digestibility of F344 rats. (6/1289)A long-term raising study was carried out on male F344/DuCrj rats with three low protein (Crude Protein (CP); 14.5, 11.5, 8.5%) and low energy (Digestible Energy (DE); 2.0 kcal/g) diets from 4 to 104 weeks of age. In rats fed the 8.5% CP diet, body weight and digestible crude protein (DCP) consumption at 10 weeks of age were lower (P < 0.05) but the body weight at 50 weeks of age was higher (P < 0.05) than in the other groups. In rats fed the 8.5% CP diet the crude fat digestibility was higher (P < 0.05), and the CP/nitrogen-corrected metabolizable energy (MEn) ratio was low. On the other hand, the mean survival time at 80 weeks of age was shorter in rats fed the 8.5% CP diet (P < 0.05). (+info)
Differentiation between obesity and insulin resistance in the association with C-reactive protein. (7/1289)BACKGROUND: Plasma C-reactive protein (CRP) concentrations are increased in obese and/or hyperinsulinemic individuals. The goal of this study was to determine if the relation between insulin resistance and CRP was independent of obesity. METHODS AND RESULTS: Plasma CRP concentrations were measured before and after 3 months of calorie restriction in 38 healthy, obese women. Steady-state plasma glucose (SSPG) concentration during a 180-minute infusion of octreotide, glucose, and insulin was used to stratify participants into insulin-resistant (IR, n=20) or insulin-sensitive (n=18) groups, similar in terms of mean age (46+/-2 versus 44+/-2 years), body mass index (32.0+/-0.4 versus 31.4+/-0.3 kg/m2), and waist circumference (96+/-2 versus 95+/-2 cm). Mean CRP (0.39+/-0.08 versus 0.12+/-0.03 mg/dL, P=0.003) concentrations were higher in the IR group, as were day-long plasma glucose and insulin responses (P<0.001). There was a significant correlation at baseline between CRP and day-long plasma integrated insulin response (r=0.47, P=0.001) but not between CRP and body mass index (r=0.14) or waist circumference (r=0.10). Weight loss was similar in the two groups (8.7+/-0.9 versus 8.4+/-0.8 kg) but was associated with significant (P<0.001) decreases in SSPG and CRP concentrations in the IR group only. Regression analysis showed that SSPG and day-long plasma insulin response were the only significant predictors of CRP concentration. CONCLUSIONS: CRP concentrations are elevated predominantly in obese individuals who are also insulin resistant and fall in parallel with weight loss-associated improvements in insulin resistance. The relation between CRP concentrations and insulin resistance is independent of obesity. (+info)
Lifelong caloric restriction increases expression of apoptosis repressor with a caspase recruitment domain (ARC) in the brain. (8/1289)Aging may increase apoptotic events and the susceptibility of the central nervous system to apoptosis. Calorie restriction has been shown to have neuroprotective effects, but the mechanisms in vivo are unknown. We investigated apoptosis and apoptotic regulatory proteins in the brain frontal cortex of 12-month-old ad libitum fed, 26-month-old ad libitum fed, and 26-month-old calorie-restricted (CR) male Fischer 344 rats (CR = 40% restricted compared to ad libitum). We found that specific DNA fragmentation indicative of apoptosis was increased with age (+124%) in the cortices of the brain and that calorie restriction attenuated this increase significantly (-36%). We determined levels of ARC (apoptosis repressor with a caspase recruitment domain), which inhibits caspase-2 activity and also attenuates cytochrome c release from the mitochondria. We found a significant age-associated decline in ARC level, which was attenuated in the brains of the CR rats. In accordance with the changes in ARC expression observed, calorie restriction attenuated the increases in cytosolic cytochrome c and caspase-2 activity with age and suppressed the age-associated rise in cleaved caspase-9 and cleaved caspase-3. However, neither age nor calorie restriction had any effect on caspase-3 and caspase-9 activities. This data provides evidence for an increased incidence of apoptosis in rat brain with age and evidence that calorie restriction has the ability to attenuate this. Furthermore, our data suggest that calorie restriction provides neuroprotection through ARC by suppressing cytochrome c release and caspase-2 activity. (+info)

Adipose tissue energy metabolism: altered gene expression profile of mice subjected to long-term caloric restriction | RTI
We investigated the influences of short-term and lifespan-prolonging long-term caloric restriction (LCR) on gene expression in white adipose tissue (WAT). Over 11,000 genes were examined using high-density oligonucleotide microarrays in four groups of 10- to 11-month-old male C57Bl6 mice that were either fasted for 18 h before death (F), subjected to short-term caloric restriction for 23 days (SCR), or LCR for 9 months and compared with nonfasted control (CO) mice. Only a few transcripts of F and SCR were differentially expressed compared with CO mice.
In this study, we provide additional evidence in support of the hypothesis that decreased caloric intake has a protective effect on MT development. Specifically, we show that a decrease in caloric intake, whether administered as chronic caloric restriction or as intermittent caloric restriction/refeeding, protects against oncogene-induced MT development. However, an identical decrease in calories and nutrients consumed by intermittent caloric restriction/refeeding was more effective in both delaying the age of MT detection and in lowering overall MT incidence than were those consumed by chronic caloric restriction.. These new findings are in contrast to the results of two previous studies that assessed the effects of chemical carcinogen-induced MT development in rats subjected to two different intermittent caloric restriction/refeeding protocols (14 , 15) . In one of these studies (14) , the degree of food restriction was substantially different between chronically calorie-restricted rats (60% ...
Caloric restriction delays age-related methylation drift | Nature Communications
In mammals, caloric restriction consistently results in extended lifespan. Epigenetic information encoded by DNA methylation is tightly regulated, but shows a striking drift associated with age that includes both gains and losses of DNA methylation at various sites. Here, we report that epigenetic drift is conserved across species and the rate of drift correlates with lifespan when comparing mice, rhesus monkeys, and humans. Twenty-two to 30-year-old rhesus monkeys exposed to 30% caloric restriction since 7-14 years of age showed attenuation of age-related methylation drift compared to ad libitum-fed controls such that their blood methylation age appeared 7 years younger than their chronologic age. Even more pronounced effects were seen in 2.7-3.2-year-old mice exposed to 40% caloric restriction starting at 0.3 years of age. The effects of caloric restriction on DNA methylation were detectable across different tissues and correlated with gene expression. We propose that epigenetic drift is a determinant
with low calorie diets low blood sugar levels can be maintained - Diabetesadviceweb
Diabetes patients are required to closely monitor their carbohydrate and sugar intake. In order that your blood sugar levels are stabilized you will each day eat approximately that same amount of food at the same time. Diabetes patients are often advised to lose weight and as such the consumption of low calorie diet is important. Low calorie diabetic diet plan makes life of diabetics less stressful. The diabetics chances of following their new dietary guidelines increases with advance knowledge of what they will be eating. With prior knowledge you will be worrying less about having diabetes and will enjoy life the way that you want. Hence, by following a low calorie diets, low blood sugar levels can be maintained and this makes eating and living with diabetes quite simple.. Low calories diets simply mean you will have a reduction in calorie intake by lowering the amount of food you eat each day. The calorie intake will be just below what you need to maintain your current weight. However, low ...

Effects of Caloric Restriction and Dietary Fat on Epithelial Cell Proliferation in Rat Colon | Cancer Research
Epidemiological studies indicate that caloric intake and dietary fat content influence colonic carcinogenesis. In rodents, caloric restriction reduces, and some fats increase, carcinogen-induced colon cancer incidence. The present study was designed to investigate the effects of caloric restriction on colonic cell proliferation (CCP) in carcinogen-treated or control rats fed low- or high-fat diets. F344 rats were treated with azoxymethane (15 mg/kg ×2) and then fed an isocaloric AIN 76A diet containing either 5 or 23% corn oil, ad libitum or calorie-restricted to 70 or 80% of the kilocalories consumed by ad libitum rats. Biopsies of the distal colon were taken at 10 and 20 weeks, and rats were sacrificed at 21 or 34 weeks on the experimental diets. Distal CCP was determined by microautoradiography after [3H]thymidine labeling in vitro or presacrifice administration in vivo. The labeling index and number of labeled cells per crypt column were significantly reduced by caloric restriction at all ...
Enzymes of glycerol and glyceraldehyde metabolism in mouse liver: effects of caloric restriction and age on activities |...
The influence of caloric restriction on hepatic glyceraldehyde- and glycerol-metabolizing enzyme activities of young and old mice were studied. Glycerol kinase and cytoplasmic glycerol-3-phosphate dehydrogenase activities were increased in both young and old CR (calorie-restricted) mice when compared with controls, whereas triokinase increased only in old CR mice. Aldehyde dehydrogenase and aldehyde reductase activities in both young and old CR mice were unchanged by caloric restriction. Mitochondrial glycerol-3-phosphate dehydrogenase showed a trend towards an increased activity in old CR mice, whereas a trend towards a decreased activity in alcohol dehydrogenase was observed in both young and old CR mice. Serum glycerol levels decreased in young and old CR mice. Therefore increases in glycerol kinase and glycerol-3-phosphate dehydrogenase were associated with a decrease in fasting blood glycerol levels in CR animals. A prominent role for triokinase in glyceraldehyde metabolism with CR was also ...

The aim of this study was to determine the effects of successive cycles of a moderately restrictive diet and refeeding with a high-fat diet on the metabolism of the adipose and hepatic tissues of obese rats. Rats were assigned to the following groups: a chow diet; a high-fat diet; a moderate caloric restriction; or a moderate caloric restriction plus refeeding. Some animals in each group were given [1-14C]triolein intragastrically, while others received an intraperitoneal injection of 3 mCi 3H2O. All animals were killed by decapitation. The retroperitoneal, visceral epididymal and omental white adipose tissues, brown adipose tissue, liver and blood were immediately removed. The lipid uptake from the diet, in vivo rate of lipogenesis, percentage of fat, lipid profile and leptin concentration were analysed. The high-fat diet promoted an increase in fatty liver (P= 0.05), adiposity mass (P= 0.05) and the plasma concentration of leptin (P= 0.05) and a decreased lipid uptake in white adipose tissue ...

AU - Kwon, Young Yon. AU - Lee, Cheol-Koo. PY - 2015/1/30. Y1 - 2015/1/30. N2 - Down-regulation of intracellular nutrient signal pathways was proposed to be a primary mechanism of caloric restriction (CR)-mediated lifespan extension. However, the link between lifespan and glucose sensors in the plasma membrane was poorly understood in yeast. Herein, a mutant that lacked glucose sensors (snf3Δrgt2Δ) had impaired glucose fermentation, showed decreased chronological lifespan (CLS), and reduced CLS extension by CR. The mutant also had reduced mitochondrial efficiency, as inferred by increased mitochondrial superoxide and decreased ATP levels. Mth1 and Std1, which are downstream effectors of the Snf3/Rgt2 pathway, were required for viability through mitochondrial function but not fermentative ...

Double X Science: 100 Years
You may have heard exclamations about antioxidants or calorie restriction. While antioxidants (the aforementioned vitamin A and vitamin E) are known to protect the body from the harmful effects of free-radicals, which occur in the normal processes of the body, evidence does not support that simply adding more antioxidants to the diet will slow aging. There are studies also showing that calorie restriction may have beneficial effects in terms of markers of aging in some animals, but many animals that are commonly used as human models do not extend longevity under calorie restriction, and such a course of action may have deleterious effects. The safety and benefits of long-term calorie restriction is currently unknown. Scientists are working towards answering these questions. ...
A Calorie-Restricted Diet Decreases Brain Iron Accumulation and Preserves Motor Performance in Old Rhesus Monkeys | Journal of...
Several measures of aging in old monkeys, including sarcopenia, poor glucoregulation, and atrophy of gray matter in the CNS, are favorably affected by a CR diet (Gresl et al., 2003; Colman et al., 2008, 2009; Anderson et al., 2009). Less is known, however, about CRs protective effect on two other markers of brain aging: the accumulation of iron and deteriorating motor performance. Iron concentrations increase naturally with age in deep nuclei (striatum, GP, SN, and RN) in both humans (Bartzokis et al., 2007; Péran et al., 2007; X. Xu et al., 2008) and monkeys (Hardy et al., 2005; Cass et al., 2007). Motor deficits also increase with age and can progress clinically to age-related disorders (Herndon et al., 1997; Lacreuse et al., 1999; Nagahara et al., 2010). In the present study, we confirmed the age-associated increase of iron in a number of brain regions that typically show the most accumulation with age, as indexed by robust negative correlations between age and R2 in GP and SN (Hallgren and ...

Recent Calorie Restriction Research: Monkeys, Squirrels, Mice, and Yeast - Fight Aging!
Researchers around the world are examining the effects of calorie restriction in many different species, and have been for years. In near all species reducing calorie intake while maintaining optimal levels of vital nutrients extends life and provides numerous health benefits. Spectacular improvements in general health and lowered risk of disease are observed in human practitioners, far more than any presently available medical technology can offer a basically healthy individual, but the jury is still out on the degree to which calorie restriction can extend maximum life span in our species and other longer-lived primates. In part this is due to a lack of data: it takes a long time to run such a study when the only reliable way to measure life extension is to wait and see, and there is little in the way of large sets of historical data to mine. Researchers currently expect calorie restriction to extend human life by only a few years, and the historical absence of evidence bears this out: if ...
Salk researchers discover first gene that specifically links calorie restriction to longevity - Salk Institute for Biological...
Having identified a key link between calorie restriction and aging also opens the door to development of drugs that mimic the effects of calorie restriction and might allow people to reap health benefits without adhering to an austere regimen that only ascetics can endure. Initially, researchers thought that the effect of calorie restriction on aging was mediated through insulin-like signaling pathways in the roundworm Caenorhabditis elegans (C. elegans), but experiments by graduate student Siler Panowski in Dillins lab suggested otherwise.. In the worm, signals passed down the insulin/IGF-1 pathway regulate a DNA-binding protein called DAF-16 that belongs to what is called the forkhead family. It was believed that DAF-16 then regulated expression of genes associated with longevity. Dillin had also identified a co-regulator in the pathway called SMK-1 that apparently worked with DAF-16 to regulate longevity.. When we asked whether DAF-16 and SMK-1 proteins were both necessary for CR-mediated ...

Whole Oats Supplementation in a Low Calorie Diet Efficiently Reduces Cardio-Metabolic Disorders in Obese Rats | South...
The hypocaloric diets (HCD) are an approach for controlling weight but can lead to a risk of nutritional deficiency. Whole grain contain bioactive com-pounds with health benefits; their incorporation into HCD can improve their nutritional value due to their richness in soluble fibers and their low glycae-mic index. The effects of incorporating oats in HCD were evaluated on growth parameters, lipid and glycaemic abnormalities, nitric oxide level and redox status in obese rats. Albinos rats were rendered obese after ingestion of a hyperlipidic (HL) diet and were then divided into three homogeneous groups: A first group was submitted for 28 days to a caloric restriction (CR) supplemented with oat (CR-Oat group). The second was fed a CR diet with-out supplementation (CR group) and the third obese group continued to con-sume the HL diet (Ob-HL). A fourth group (T) of normal weight rats is taken as a reference. Body weight, food and energy intake, glycaemia, glycosylated hemoglobin, insulinemia and ...
Impact of Caloric Restriction on Health and Survival in Rhesus Monkeys From the NIA Study - PubMed
Calorie restriction (CR), a reduction of 10-40% in intake of a nutritious diet, is often reported as the most robust non-genetic mechanism to extend lifespan and healthspan. CR is frequently used as a tool to understand mechanisms behind ageing and age-associated diseases. In addition to and indepen …
Woman with Meal - 4 Week - Shake That Weight
Achieving a healthy weight target is all about finding the right balance between the amount of energy (kals) you consume and the amount your burn off . If you are actively trying to lose weight then eating healthy meals and maintaining physical fitness is the key to success!. Sometimes you need a bit of extra help, which is where a very low calorie diet or VLCD, can be the correct choice for you. The principal is simple, to lose weight you need to use more energy than you consume. A Very low calorie diet lowers your daily calorie intake significantly more than traditional diets.. This means more rapid weight loss than traditional diets.. VLCD plans like shake that weight are now recognised by the NHS and are openly discussed as a method of successful dieting on NHS choices.. The national institute for clinical excellence (nice) recommends that VLCDs (diets under 1000 calories) should only be followed constantly for 12 weeks and then you should take a break. This diet is also not recommended for ...
A cell non-autonomous mechanism of yeast chronological aging regulated by caloric restriction and one-carbon metabolism
Caloric restriction (CR) improves healthspan and lifespan of organisms ranging from yeast to mammals. Understanding the mechanisms involved will uncover future interventions for aging associated diseases. In budding yeast, Saccharomyces cerevisiae , CR is commonly defined by reduced glucose in the growth medium, which extends both replicative and chronological lifespan (CLS). We found that conditioned media collected from stationary phase CR cultures extended CLS when supplemented into non-restricted (NR) cultures, suggesting a potential cell non-autonomous mechanism of CR-induced lifespan regulation. Chromatography and untargeted metabolomics of the conditioned media, as well as transcriptional responses associated with the longevity effect, pointed to specific amino acids enriched in the CR conditioned media (CRCM) as functional molecules, with L-serine being a particularly strong candidate. Indeed, supplementing L-serine into NR cultures extended CLS through a mechanism dependent on the ...
The role of Ames dwarfism and calorie restriction on gut microbiota.
The gut microbiome (GM) represents a large and very complex ecosystem of different microorganisms. There is an extensive interest in the potential role of the GM in different diseases including cancer, diabetes, cardiovascular diseases, and aging. The GM changes over the lifespan and is strongly associated with various age-related diseases. Ames dwarf (df/df) mice are characterized by an extended life- and healthspan, and although these mice are protected from many age-related diseases, their microbiome has not been studied. To determine the role of microbiota on longevity animal models, we investigated the changes in the GM of df/df and Normal control (N) mice, by comparing parents before mating and littermate mice at three distinct time points during early life. Furthermore, we studied the effects of a 6-month calorie restriction (CR), the most powerful intervention extending the lifespan. Our data revealed significant changes of the GM composition during early life development, and we ...
Caloric restriction improves health-related quality of life in healthy normal weight and overweight individuals | Evidence...
Studies have demonstrated that caloric restriction (CR) increases longevity in animals and also decreases the risk of diabetes, cardiovascular disease and cancer in humans without obesity.1 ,2 It is hypothesised that these favourable CR effects may be related to a reduction in metabolism, reduced core temperature and lowered triiodothyronine(T3).3 While it is unlikely that studies will ascertain whether CR extends life, intermediate length studies may be able to determine the safety, tolerability and feasibility of CR and its effects on chronic disease development and biomarkers correlated with longevity.2 This study aimed to examine the sustained effects of a 25% CR on health-related quality of life (QOL) in individuals … ...

Whole Health Source: August 2012
Recent findings have caused me to seriously question this narrative. One of the first challenges was the finding that genetically wild mice (as opposed to inbred laboratory strains) do not live longer when their calorie intake is restricted, despite showing hormonal changes associated with longevity in other strains, although the restricted animals do develop less cancer (1). One of the biggest blows came in 2009, when researchers published the results of a study that analyzed the effect of calorie restriction on lifespan in 41 different strains of mice, both male and female (2). They found that calorie restriction extends lifespan in a subset of strains, but actually shortens lifespan in an even larger subset. Below is a graph of the effect of calorie restriction on lifespan in the 41 strains. Positive numbers indicate that calorie restriction extended life, while negative numbers indicate that it shortened life ...

Practicing Family Medicine: The Late Clive McCay, Life Prolongation and Caloric Restriction
McCay used mature rats that were given the opportunity to grow and develop. He then restricted calories without restricting nutrients. This resulted in a significant prolongation of life. Since, this finding was replicated by many. Nowadays the fact that caloric restriction prolongs life does not need extra proof. Researchers are merely trying to to explain this phenomenon. As usual there is a focus on the physiology to try and develop drugs that will prolong life. I think we should just take this caloric intake life extension relationship as a fact and focus our effort on finding ways of applying it. McCay did that by designing McCays loaf, a nutrient dense loaf ...

Fasting the microbiome to treat diabetes | Science Translational Medicine
It is known that the microbiome has a role in diabetes pathophysiology, but more recently it has been suggested that the microbiome also moderates the efficacy of certain diabetes therapies. In an article by Beli et al., the authors demonstrate a potential link between the microbiome and the beneficial effects of dietary therapy. In contrast to chronic caloric restriction, intermittent fasting limits food intake to certain hours of the day, which is believed to benefit metabolic outcomes with relevance to diabetes.. Using the db/db mouse model of diabetes, the authors demonstrated that intermittent fasting improved survival and prevented the development of retinopathy. Each outcome was independent of glycated hemoglobin concentrations. So, the authors turned their attention to the intestinal microbiome to explain the benefit of intermittent fasting, Studies of fecal bacterial ecology demonstrated clear changes in phylogenetic distributions accompanied by differences in the mucosa, including ...
Opposing effects of age and calorie restriction on molecular determina by Jason N. Peart, Louise S. See Hoe et al.
We test the hypothesis that moderate calorie restriction (CR) reverses negative influences of age on molecular determinants of myocardial stress resistance. Postischemic contractile dysfunction, cellular damage, and expression of regulators of autophagy/apoptosis and of prosurvival and prodeath kinases were assessed in myocardium from young adult (YA; 2- to 4-month-old) and middle-aged (MA; 12-month-old) mice, and MA mice subjected to 14 weeks of 40% CR (MA-CR). Ventricular dysfunction after 25%±2%), as was cell death indicated by troponin I (TnI) efflux (1,701±214 ng vs. 785±102 ng in YA). MA hearts exhibited 30% and 65% reductions in postischemic Beclin1 and Parkin, respectively, yet 50% lower proapoptotic Bax and 85% higher antiapoptotic Bcl2, increasing the Bcl2/Bax ratio. Age did not influence Akt or p38-mitogen-activated protein kinase (MAPK) expression; reduced expression of increasingly phosphorylated ribosomal protein S6 kinase (p70S6K), increased expression of dephosphorylated glycogen
Effects of the Dietary Approaches to Stop Hypertension Diet Alone and in Combination With Exercise and Caloric Restriction on...
Our findings demonstrate that adherence to the DASH diet alone, although sufficient to modify BP values,12 resulted in significant improvements in metabolic indices of cardiovascular risk only when accompanied by aerobic exercise and weight loss. In the DASH-WM group, participants lost an average of 19 pounds over 4 months and increased their aerobic capacity by 19%. Although both the DASH-A and DASH-WM groups achieved clinically meaningful reductions in BP and improvements in other cardiovascular biomarkers of risk, as described in our earlier publication,12 only DASH-WM participants demonstrated significant improvements in glucose tolerance and insulin sensitivity.. Although the DASH diet has been shown to reduce BP in controlled feeding studies7,8 and in studies of free-living individuals,9,12 the present study found that ENCORE participants who adhered to the DASH diet but did not exercise or lose weight achieved minimal improvements in glucose metabolism, insulin sensitivity, and lipids, ...

Diabetes type 2 may reverse with a low calorie diet: Study
Having type 2 diabetes, also called adult-onset or non-insulin dependent diabetes, has become very common in todays society. An estimated one in three Americans will develop type 2 diabetes by the year 2050, according to new projections by the Center for Disease Control and Prevention (CDC).. This growing trend is in direct correlation with the increasing rates of obesity in American citizens and has even extended to our younger population. This prevalence of type 2 diabetes has made health professionals around the globe concerned about the overall health of those affected, with mental well-being also in jeopardy.. According to a new report, type 2 diabetes goes into remission in many patients who undergo bariatric weight-loss surgery, a procedure that reduces the size of the stomach. This leads to less calorie intake, resulting in significant weight loss.. A team of researchers sought to find out exactly why this caloric restriction rapidly reverses type 2 diabetes.. ...
In mice, calorie restriction reduces fat but increases fur | EurekAlert! Science News
Calorie restriction may help mice stay slim and live longer, but it also means less fat to keep their bodies warm. Researchers in Brazil have found that mouse skin responds to caloric restriction by stimulating fur growth, increasing blood flow, and altering cell metabolism to increase energy efficiency. The study, published Sept. 12 in Cell Reports, reveals that animals may use this as an evolutionary adaptation to stay warm -- and alive -- in limited food conditions.

Studies of Sir2 and caloric restriction mimetic pathways in aging :: University of Southern California Dissertations and Theses
Increased dosage of Sir2, a conserved histone deacetylase, extends replicative life span in yeast, and possibly worms, and flies and protects mammals against certain diseases. Previous work in our lab has shown that it is the lack of Sir2 and not its overexpression that promotes resistance to different stresses and extends chronological lifespan when combined with calorie restriction (CR) and/or mutations in the Tor/Sch9 or Ras pathways in yeast. To identify genes and pathways that mimic the effects of CR on aging and cellular protection we explored the role of Sir2 in regulating stress response and examined the genetic interaction between Sir2 and stress resistance transcription factors, Msn2/4 and Gis1. Our results suggest that Msn2/4 and Gis1 are required for the enhanced stress resistance of sir2Δ mutant and the further extension of chronological lifespan of sir2Δ mutant under caloric restriction. In agreement with this result, the serine/theronine kinase Rim15, a positive regulator of ...

Niges Diet & Nutrition Blog: Very Low Calorie Diets (VLCDs)
b) High risk of developing Gallstones. Rapid weight loss results in an increase in the concentration of cholesterol in bile. This increases the risk factor for gallstones, something that women have a higher risk factor for than men. Theres an acronym FFFF for people who are at a high risk of developing gallstones. It stands for Female, Forty, Fat, Fair. What makes the situation even worse is that VLCDs are very low in fat. The gallbladder is a muscular bag which stores bile. When dietary fat is eaten, this stimulates the secretion of cholecystokinin, which then stimulates contraction of the gallbladder muscle, which expels bile from inside the gallbladder into the duodenum. The lower the fat content of a meal, the less the gallbladder contracts and gallbladder stasis can result with only 2g of fat per meal. See The role of gallbladder emptying in gallstone formation during diet-induced rapid weight loss. The problem with this study is that the two groups of subjects were not eating the same ...

Uncoupling lifespan and healthspan in Caenorhabditis elegans longevity mutants | PNAS
Previously, the word healthspan has been used in many scientific contexts, but the definition has been ambiguous at best. Therefore, in this study, we focused on providing a conceptual framework of healthspan that can be easily verified in a laboratory setting using C. elegans. The current study makes no claim that the healthspan parameters tested cover all aspects of healthspan, nor does it make any assumptions that antiaging therapies that extend lifespan cannot coincide with an increase in healthspan. Rather, we highlight limitations of aging studies focused solely on lifespan extension.. Here we defined healthspan broadly by testing multiple assays as the animals aged. We tested wild type as our benchmark and then compared data from four long-lived mutants with wild-type health. From these data, we calculated and compared both the chronological number of days an animal is healthy vs. frail and the percent of the physiological lifespan the animal spends in each state (healthspan:gerospan ...

A Non-calorie-restricted Low-carbohydrate Diet is Effective as an Alternative Therapy for Patients with Type 2 Diabetes
Objective Although caloric restriction is a widely used intervention to reduce body weight and insulin resistance, many patients are unable to comply with such dietary therapy for long periods. The clinical effectiveness of low-carbohydrate diets was recently described in a position statement of Diabetes UK and a scientific review conducted by the American Diabetes Association. However, randomised trials of dietary interventions in Japanese patients with type 2 diabetes are scarce. Therefore, the aim of this study was to examine the effects of a non-calorie-restricted, low-carbohydrate diet in Japanese patients unable to adhere to a calorie-restricted diet ...

Age and/or disease may compromise salivary gland function. In order to gain insight into the role of calorie restriction (CR) on immunoglobulin (Ig) production, we determined the effect of ad libitum (AL) feeding and CR in young (3 months) and old (18-24 months) C57BL/6 mouse submandibular glands (SM). The SM tissues were fragmented and cultured in the absence (control) or presence of either Th-1 cytokines, such as interleukin-2 (IL-2) and interferon-γ (IFN-γ), or Th-2 cytokines, e.g. IL-4 and IL-5, for seven days. Culture supernatants were then analyzed for immunoglobulin A (IgA), IgM, and IgG(2α) ...
The effect of chronic (CCR) and intermittent (ICR) caloric restriction on serum adiponectin and leptin levels was investigated in relation to mammary tumorigenesis. 10-wks old MMTV-TGF-alpha female mice were assigned to ad libitum-fed (AL) (AIN-93M diet), ICR (3-wks 50% caloric restriction, AIN-93M-mod diet, 2x protein, fat, vitamins, and minerals followed by 3-wks 100% AL consumption of AIN-93M), and CCR (calorie and nutrient intake matched for each 6-wks ICR cycle, ~75% of AL) groups. Mice were sacrificed at 79 (end of restriction) or 82 (end of refeeding) wks of age. Serum was obtained in cycles 1, 3, 5, 8, 11 and terminal. Mammary tumor incidence was 71.0%, 35.4%, and 9.1% for AL, CCR and ICR mice, respectively. Serum adiponectin levels were similar among groups with no impact of either CCR or ICR. Serum leptin level rose in AL mice with increasing age but was significantly reduced by long-term CCR and ICR. The ICR protocol was also associated with an elevated adiponectin:leptin ratio. In ...

Abstract P066: A Refined Carbohydrate Diet Attenuates Weight Loss in Insulin Resistant Individuals | Circulation
Introduction: Weight loss is attenuated in individuals with insulin resistance (IR) who follow a traditional high-carbohydrate, calorie-restricted diet. However, the type of carbohydrate may modulate this response. We studied the effects of whole grains vs. refined grains on weight loss in individuals with increased waist circumference (M: ,102 cm, F: ,88 cm) and at least 1 other metabolic syndrome characteristic.. Hypothesis: In a secondary analysis, we hypothesized that IR individuals (estimated by a triglyceride:high-density lipoprotein cholesterol ratio , 3.5) would lose more weight on a hypocaloric diet with whole grains vs. refined grains.. Methods: Overweight or obese (BMI 25-42 kg/m2) men and women (n=50) 35-55 yrs were randomized to a controlled-feeding diet with whole vs. refined grains for 12 weeks [6 weeks isocaloric then 6 weeks hypocaloric (∼500 kcal/d)].. Results: [All comparisons represented as IR mean±SEM vs. insulin sensitive (IS) mean±SEM, p-value)]. Compared to the IS ...
Expression of Longevity Genes in Response to Extended Fasting - Full Text View - ClinicalTrials.gov
Coronary heart disease (CHD) is the largest contributor to morbidity and mortality in the Western world and is associated with high-calorie diet, high body mass, and a variety of other factors. CHD can lead to myocardial infarction (MI) and other embolic events. A growing body of evidence suggests that relatively low caloric intake in the diets of a variety of animals increases longevity and preliminary evidence among humans indicates that such caloric restriction reduces risk factors for CHD, including cholesterol levels, blood pressure, glucose, and obesity. Caloric restriction has also been shown to alter the expression of certain genes, especially the forkhead box (FOX) O and sirtuin (SIRT) genes whose over-expression has been shown to increase longevity in animal models. Extended avoidance of caloric intake, also called fasting or short-term starvation, has been shown to increase expression of the FOXA genes that have similar sequence and function as the FOXO genes and that have been shown ...
Lose Weight With HCG Ultra Diet Drops
Does the HCG diet work? Yes, it does and here is why. A low calorie diet used in combination with a hormone known as HCG can cause weight loss that is quick, easy and safe. It is estimated most dieters who participate in the HCG diet plan are able to lose ½ to 1 pound per day. The HCG weight loss plan is based on hypothalamus signaling. HCG combined with a low calorie diet (1,000 to 1,250 calories) notifies the body to signal the hypothalamus to release accumulated fat that has built up in the body. The fat release mechanism allows the body to be fueled by as many calories as necessary. The additional calories to help fuel your body is taken from the already stored fat. The already built up fat that has accumulated is in reality stored energy. That stored energy can be used as the body releases it, but the body does not give up fat easily. The body burns lean muscle first and when the muscle has been ravaged, stored fat is dragged kicking and screaming into the burn zone. HCG transposes the ...

MIT researcher sheds light on why cutting calories keeps organisms alive and healthier for longer | MIT News
CAMBRIDGE, Mass. -- A Massachusetts of Technology researcher has helped yeast live longer by putting it on a strict diet.. His research team reports in the Sept. 22 issue of Science that an enzyme co-factor and a gene join forces with the reduction in calories to slow down aging.. The recent work of MIT biology professor Leonard Guarente may help explain the long-known fact that restricting calories to 70 percent of normal levels helps mice and other creatures live longer, healthier lives.. The billion-dollar question is: What is the mechanism through which this works?. Guarente, who studies the silenced information regulator (SIR2) gene and its apparent ability to slow the aging process, showed that in yeast, calorie restriction leads to an increase in the activity of the Sir2 protein (made by the SIR2 gene) required for genomic silencing. If the SIR2 gene is deleted or the co-factor levels in cells are depressed, the benefits of calorie restriction on longevity are not realized.. In yeast, age ...
Low Calorie Food (12) | Art 2 Muse
Maddi, This is a good checklist as I like almost every part on it. I am glad to know in regards to the detrimental calories. However… they have a number of properties that make them an ideal meals, each for weight reduction and optimum health. Most those that adopt a excessive fiber low calorie meals diet as a part of a wholesome eating plan. Hopefully, you will not make the identical mistakes that I did and can understand why it is vital to eat a low calorie breakfast every single morning, it doesnt matter what! There is a limited list of unfavorable calorie foods, and limited methods to organize them, especially with out including extra energy.. There are many quick, straightforward and scrumptious low calorie breakfast concepts which you could make at house. However, its best to always check the labels of any cereal earlier than including it to your weight loss plan for this objective as a result of some are packed full of sugar. While eating them alone wont melt the fats off you, its ...

Put on low calorie diet for fatty liver - Diet Blog
Fatty liver disease is characterized by the presence of abnormal amounts of fat in the liver, which is called steatosis. If you have fat in your liver but no other damage, you are thought to have nonalcoholic fatty liver disease NAFLD. If left untreated, inflammation and liver cell damage can occur, causing a disease called nonalcoholic steatohepatitis NASH. NASH is associated with cirrhosis, end-stage liver disease, and liver transplantation, and is often associated with cardiovascular-related diseases. Dietary changes inducing weight loss, adding nutrient-dense, antioxidant-packed foods, such as fruits and vegetables, can reverse or prevent the progression of the disease. Weight loss, particularly in the abdominal or adipose tissue, can help to reduce fat in the liver. Limiting refined carbohydrates, simple sugars, fried foods, processed foods, and foods high in saturated fat will also be important in treatment. Because fatty liver disease is often associated with obesity, insulin resistance, ...
TV special shows diet reverses Type 2 Diabetes - Healthcanal.com : Healthcanal.com
The Food Hospital special: Extreme Diet Ward follows ground-breaking research by Professor Roy Taylor which found people could reverse their diabetes with an extreme low calorie diet alone.. Affecting two and half million people in the UK - and on the increase - Type 2 diabetes is a long-term condition caused by too much glucose, a type of sugar, in the blood. In the clinical trial published two years ago, 11 people reversed their diabetes by drastically cutting their food intake to just 600 calories a day for two months. And three months later, seven remained free of diabetes. For the Channel 4 programme, six women embarked on a low calorie diet with three of the following this extreme regime.. Professor Roy Taylor of Newcastle University who led the study and also works for The Newcastle-Upon-Tyne Hospitals NHS Foundation Trust said: To have people free of diabetes after years with the condition is remarkable - and all because of an eight week diet. This is a radical change in understanding ...
Micronutrient deficiency in obese subjects undergoing low calorie diet | Nutrition Journal | Full Text
The present study clearly confirms previous observations stating that obese individuals are characterized by micronutrient deficiencies [4, 6-8, 10-13]. The deficiencies are suggested by both low intake and low serum and intracellular levels as shown by our data.. The study demonstrates an insufficient dietary micronutrient supply of retinol, ß-carotene, vitamin D, vitamin E, vitamin C, folate, iron, and calcium in obese individuals. A highly significant difference compared to the reference population, both in men and women, was observed for ß-carotene, folate, vitamin C, and fiber - nutrients which are essentially found in fruits, vegetables and whole-grain products, thus pointing to an unbalanced diet leading to micronutrient deficiencies.. Evaluation of nutritional intake has some methodological weakness such as underreporting that limits the interpretation of dietary record data. The resulting error is possibly even more distinct in obese subjects [21-24]. However, underreporting ...
Epigenetic regulation of caloric restriction in aging | BMC Medicine | Full Text
Several HDAC families have been identified, including class III NAD+-dependent HDACs such as Sirtuin 1. Sirtuin 1 (SIRT1) in mammals, and its orthologs in other species (Sirtuin 2 in yeast), deserves special attention due to its fundamental impact on aging regulation and CR-related lifespan extension [32-36]. The unusual enzymatic activity of SIRT1, which largely depends on NAD/NADH ratio, a key indicator for oxygen consumption, respiratory chain and metabolic rate, suggests that this protein is tightly connected to the metabolic state of cells.. The promising effect of SIRT1 in mediating CR and lifespan extension is supported by a diverse range of animal models, human subjects and even in vitro CR cellular systems [31-33, 35, 36, 81-85]. Activation of SIRT1 is frequently seen in different animal organs affected by CR, whereas inactivation of SIRT1 may lead to abolition of lifespan extension, suggesting a pivotal role of SIRT1 in lifespan regulation during CR. SIRT1 was initially discovered for ...

Also recognizing what worked 6 months to 1 year ago may not work today. Our bodies change over time and we have to adapt to those changes. So many factors affect your blood glucose levels; you will face hormonal changes, stress related changes, and your pancreas may not be working as well today as it did a year ago and we wouldnt expect it to. Just as the heart of an 18 year old person is much stronger than it will be at the age of 50 years of age, your pancreas function will decline with age with the normal aging process. Many of my patients throughout the years have came to me feeling so defeated because now they have to go on medication or insulin. They are so relieved to hear this may not be due to anything they have caused by overeating or weight gain, it may be just the unfortunate natural progression of diabetes. Until we discover cures for the different types of diabetes, this is what we face. ...

Clenbuterol Hydrochloride Explained | IronMag Bodybuilding Blog
Dan Duchaine. So obviously, if people are using it unless they run out… there is still some perceived metabolic effect even after the initial hurricane of fat loss is over. Some of this might be a general percentage that the metabolism remains increased, or potentially even the anabolic/anti-catabolic effect of it. Most bodybuilders will use it for their last 12 weeks leading up to a contest, non-stop, and feel that it provides some benefit for the entire time (albeit less at the end). Interestingly, some rodent data exists that would suggest clenbuterol is more efficient on a calorie-restricted diet.. The anabolic effect of clenbuterol isnt like anabolic steroids, by any stretch of the imagination. Its noticeable, and with the fat loss that it provides, some amazing physique transformations are possible. Here, were talking about a few pounds of muscle gained, at most - but when you combine that with significant fat loss, the results can be fairly spectacular.. Its unknown exactly how ...

About Ginny - Hypothyroid Chef
In 2011, two months after the birth of my son James, I was diagnosed with hypothyroidism. I thought my fatigue was normal for someone recovering from a c-section and breastfeeding a newborn. But my doctor informed me after some postpartum bloodwork that my thyroid function was low.. For the first few years I managed it with medication (Levothyroxine), and still do. But each year when I visited my doctor to run blood tests and see if my medication needed adjustment, I would tell her I didnt feel great, and wondered if my numbers were off, or if maybe the medication wasnt addressing all my symptoms. I felt tired most of the time, even upon waking. I couldnt lose weight even though I had been on a calorie-restricted diet for three years. I was sick a lot, sometimes for months at a time, doing round after round of antibiotics for things like ear infections, strep throat, tonsillitis, you name it. My brain felt foggy, I couldnt trust my memory, my joints ached. Looking back, its no wonder I ...
Progesterone Pregnancy Archives
HCG, or Human Chorionic Gonadotropin, is a hormone that is naturally produced by the placenta during pregnancy. This hormone goes a long way toward controlling the metabolic functioning of the pregnant woman. In addition, it helps to prevent the deterioration of the corpus luteum in the ovary. As a result, the corpus luteum is able to continue producing the progesterone that is necessary during pregnancy.. Since HCG is produced during pregnancy, medical professionals routinely check for elevated levels of HCG when testing for pregnancy. As a hormone that is associated with pregnancy, HCG is used to help treat women with fertility issues as well as other hormonal problems.. In addition to the effects that HCG has on hormones, it has also gained a great deal of popularity as a dietary aid. In order to assist men and women with weight loss, HCG is injected into the dieters muscle on a regular basis. When the injection is taken in conjunction with a very low calorie diet of 500 calories per day, ...
Notes from Dr. RW: Relationships between exercise, hunger and energy balance
High-intensity exercise causes a short-term suppression of hunger of approximately 15 to 60 minutes. Although there is evidence for compensatory food consumption, it usually does not make up for the energy deficit created by exercise. The exception occurs when individuals consume or reward themselves with energy-dense foods or drink. Because people tend to eat the same volume of food each day, on days when they exercise, they will remain in an energy deficit. However, on sedentary days, a positive energy balance is likely if caloric restriction is not imposed, which could result in weight gain. Caloric restriction alone leads to loss of lean body mass, while the inclusion of exercise with an energy deficit helps conserve lean tissue. ...

mTOR and the Age-Related Decline in Stem Cell Activity - Fight Aging!
As a companion piece to an earlier post on the relationship between the mechanistic target of rapamycin (mTOR) gene and cellular senescence in aging, you might take a look at the research here that investigates the relationship between mTOR and the characteristic decline in stem cell activity that occurs with advancing age. In addition to the large body of research focused on insulin and growth hormone metabolism, work on mTOR is among the most active areas of study resulting from investigations of calorie restriction. The practice of calorie restriction has been shown to slow aging in near all species and lineages studied to date, so insofar as the response to calorie restriction is partially mediated through mTOR, we should expect mTOR to have some connection to most of the causes of aging. Unfortunately, calorie restriction has only a small effect on life span in our species. The research community doesnt yet know exactly how small, but it would be very surprising for it to be greater than ...

Preclinical data suggests that protein and calorie restriction (PCR) might improve treatment tolerability without impairing antitumor efficacy. Therefore, we have studied the influence of PCR on irinotecan pharmacokinetics and toxicity. In this crossover trial, patients with liver metastases of solid tumors were included and randomized to treatment with irinotecan preceded by 5 days of PCR (~ 30% caloric and ~ 70% protein restriction) during the first cycle and a second cycle preceded by a normal diet or vice versa. Pharmacokinetic blood sampling and biopsies of both healthy liver and liver metastases were performed. The primary end point was the relative difference in geometric means for the active metabolite SN-38 concentration in healthy liver analyzed by a linear mixed model. No significant differences were seen in irinotecan (+ 16.8%, P = 0.22) and SN-38 (+ 9.8%, P = 0.48) concentrations between PCR and normal diet in healthy liver, as well as in liver metastases (irinotecan: −38.8%, P = ...
Longevity Archives - Gut Reactions
Intermittent fasting is one way to reduce body fat that is increasing in popularity because it is so simple to do. But there are other advantages besides weight loss.. It has long been known that dietary restriction increases lifespan.. Whether it takes the form of reduced calories, reducing one of the nutrient types (protein, fat, or carbohydrate), or fasting occasionally (not eating for a day or two), dietary restriction has been shown to have beneficial effects in all manner of organisms, such as yeast, worms, flies, mice, monkeys, and humans.. When studying lifespan, it helps to work with organisms that have very short lifespans, where the effects of an intervention can be seen in the researchers lifetime. This is why much of the work has been done in short-lived species such as yeast, fruit flies, tiny worms, and mice. In these organisms, we see common mechanisms that dietary restriction triggers to increase lifespan, and we see those same mechanisms at work in longer lived ...
PLOS ONE: A Low Dose of Dietary Resveratrol Partially Mimics Caloric Restriction and Retards Aging Parameters in Mice
Resveratrol in high doses has been shown to extend lifespan in some studies in invertebrates and to prevent early mortality in mice fed a high-fat diet. We fed mice from middle age (14-months) to old age (30-months) either a control diet, a low dose of resveratrol (4.9 mg kg−1 day−1), or a calorie restricted (CR) diet and examined genome-wide transcriptional profiles. We report a striking transcriptional overlap of CR and resveratrol in heart, skeletal muscle and brain. Both dietary interventions inhibit gene expression profiles associated with cardiac and skeletal muscle aging, and prevent age-related cardiac dysfunction. Dietary resveratrol also mimics the effects of CR in insulin mediated glucose uptake in muscle. Gene expression profiling suggests that both CR and resveratrol may retard some aspects of aging through alterations in chromatin structure and transcription. Resveratrol, at doses that can be readily achieved in humans, fulfills the definition of a dietary compound that mimics some

U-M researcher examines the cell s housekeeping habits
Autophagy may even provide a clue to the mythical fountain of youth. Autophagy activity is known to decrease with aging, and experiments in which autophagy was blocked in the C. elegans nematode worm resulted in dramatically shorter life spans for the 1 millimeter creatures. Conversely, more autophagy may prolong life. This fits with findings that caloric restriction can extend the life span in rats, since near-starvation triggers more autophagy as the cells recycle parts of themselves for fuel. Sustained autophagy may also increase longevity by protecting cells against free radical damage and mutations in DNA. This is becoming a very hot field, Klionsky said. We have a lot of really interesting questions to explore in autophagy ...

Simple caloric restriction (not IF) increases autophagic processes:. https://www.sciencedirect.com/science/article/pii/S2211124715014837. Its the caloric restriction that activates autophagy not the fasting.. You can do intermittent fasting 16+ hours a day but overeating calories during your eating window and not really ramp up autophagy much above baseline. Also fasting is not required to activate autophagy. Exercise also activates autophagy even in a fed state. In this study subjects got continuous glucose infusions while doing exercise and had great autophagy signaling that those doing a 36 hour fast.. https://www.physiology.org/doi/full/10.1152/japplphysiol.01116.2014.

Strategies for Preventing Age and Neurodegenerative Disease-associated by Vedad Delic
Mitochondrial dysfunction plays a pivotal role in the development of aging phenotypes and aging-associated neurodegenerative disorders, such as Alzheimers disease (AD), Parkinsons disease (PD) and Amyotrophic lateral sclerosis (ALS). Strategies that restore mitochondrial dysfunction may rescue the deficits of central metabolism in these disorders and improve cell survival. For example, we found that modulating the mTOR signaling pathway in a tissue culture model of aging-induced mitochondrial DNA mutation enhanced mitochondrial function as evidenced by increased oxygen consumption. Our previous melatonin studies also led us to hypothesize that caloric restriction and the hormone melatonin would reverse brain mitochondrial dysfunction in animal models of AD. Although caloric restriction did not improve mitochondrial function in a transgenic P301L tau model of AD, novel insight into the regulation of F0-F1 ATP synthase activity under CR was gained that may help explain the protective effects of CR in

Pennington Biomedical Research Center
A: The study was actually designed to find out why individuals do not lose weight, especially because they are burning more calories. The study examined all possibilities using a rigorous mathematical approach. The study established that vigorous exercise did result in increased food consumption. The study also determined that metabolism slowed during vigorous exercise if intake remained unchanged. Additionally, the study also established that lean (muscle) mass decreased less during aerobic exercise in comparison to diet restriction. We found that a larger fraction of weight gained (if one gained weight) during exercise is gained as lean mass. That is, if you lose weight through exercise, you lose mostly fat mass, and if you gain weight during exercise, you gain mostly lean mass. This is good news for all of us who want to lose fat.. 1.

Comment on Antidepressants and caloric restriction, whats the connection?
Psychology is the study of behavior and mental state; psychological changes are changes in behavior and mental state. Yes, they are ultimately produced by some change in neurophysiology. My problem is that in popular use and apparently medical training (see MarkH of denialism blog and Jake of Pure Pedantry) the us of psychological is used in addiction and other mental disorders as a minimization technique. To suggest the problems are less real or somehow less serious or medically significant for patients. You seem to be saying that psychological just means the brain and behavior. So why do we never hear of cardiac addiction or gastrointestinal addiction or the like? There are both GI and cardiac symptoms of withdrawal and acute drug use, after all.. To use a philosophers trick, imagine that the same physiological changes took place, but did not alter behavior. Would we consider the effect to be of the same magnitude? If not, then there must be some component that does not lie within ...
