  • Ratio
  • It is several times more potent than DHEA in stimulating the thermogenic enzymes of the liver, promotes basal metabolism, and helps to increase the lean/adipose ratio. (integrativepsychiatry.net)
  • The modern term "body mass index" (BMI) for the ratio of human body weight to squared height was coined in a paper published in the July 1972 edition of the Journal of Chronic Diseases by Ancel Keys and others. (wikipedia.org)
  • Some athletes (e.g. gymnasts, basketball and soccer players) have a high muscle to fat ratio and may have a BMI that is misleadingly high relative to their body fat percentage. (wikipedia.org)
  • In this study, a healthy diet was defined as one high in fiber, with a high polyunsaturated to saturated fat ratio, lower trans fats consumption, and a lower mean glycemic index. (wikipedia.org)
  • percentage of body fat
  • If body fat is the operative characteristic, for example, then why should women, who have a higher percentage of body fat than men at any given BMI value, have a shallower slope of blood pressure with BMI? (ahajournals.org)
  • People of Asian descent have different associations between BMI, percentage of body fat, and health risks than those of European descent, with a higher risk of type 2 diabetes and cardiovascular disease at BMIs lower than the WHO cut-off point for overweight, 25 kg/m2, although the cutoff for observed risk varies among different Asian populations. (wikipedia.org)
  • Epidemiologically, the percentage of body fat in an individual varies according to sex and age. (wikipedia.org)
  • subject's
  • Reduce" can be defined relative to the subject's previous intake before intentionally restricting calories, or relative to an average person of similar body type. (wikipedia.org)
  • DEXA
  • Lean body mass has 3 formulas to work it out Instead of mathematical estimation the actual value of LBM may be calculated using various technologies such as Dual-energy X-ray absorptiometry (DEXA). (wikipedia.org)
  • person's
  • B M I = mass kg height m 2 = mass lb height in 2 × 703 {\displaystyle \mathrm {BMI} ={\frac {{\text{mass}}_{\text{kg}}}{{\text{height}}_{\text{m}}^{2}}}={\frac {{\text{mass}}_{\text{lb}}}{{\text{height}}_{\text{in}}^{2}}}\times 703} BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients. (wikipedia.org)
  • A frequent use of the BMI is to assess how much an individual's body weight departs from what is normal or desirable for a person's height. (wikipedia.org)
  • mortality
  • In some studies, low body weight has been associated with increased mortality, particularly in late middle-aged or elderly subjects. (wikipedia.org)
  • Low body weight in the elderly can be caused by pathological conditions associated with aging and predisposing to higher mortality (such as cancer, chronic obstructive pulmonary disorder, or depression) or of the cachexia (wasting syndrome) and sarcopenia (loss of muscle mass, structure, and function). (wikipedia.org)
  • One of the more famous of such studies linked a body mass index lower than 18 in women with increased mortality from noncancer, non−cardiovascular disease causes. (wikipedia.org)
  • density
  • Specifically, comparing the bone mineral density of children to the reference data of adults (to calculate a T-score) will underestimate the BMD of children, because children have less bone mass than fully developed adults. (wikipedia.org)
  • Because DXA calculates BMD using area (aBMD: areal Bone Mineral Density), it is not an accurate measurement of true bone mineral density, which is mass divided by a volume. (wikipedia.org)
  • Short-term studies in humans report a loss of muscle mass and strength and reduced bone mineral density. (wikipedia.org)
  • With a well engineered weighing system, body density can be determined with great accuracy by completely submerging a person in water and calculating the volume of the displaced water from the weight of the displaced water. (wikipedia.org)
  • If there were no errors whatsoever in measuring body density, the uncertainty in fat estimation would be about ± 3.8% of the body weight, primarily because of normal variability in body constituents. (wikipedia.org)
  • measurement
  • The BMI may also be determined using a table or chart which displays BMI as a function of mass and height using contour lines or colours for different BMI categories, and which may use other units of measurement (converted to metric units for the calculation). (wikipedia.org)
  • However, accurate measurement of body fat percentage is much more difficult than measurement of BMI. (wikipedia.org)
  • higher
  • A correlation between occupational sitting specifically and higher body mass index has been demonstrated, but causality has not yet been established. (wikipedia.org)
  • indicator
  • Because cardiac output is related to the quantity of blood delivered to various parts of the body, it is an important indicator of how efficiently the heart can meet the body's demands for perfusion. (wikipedia.org)
  • However
  • specify] However, it has been suggested that, while very accurately measuring minerals and lean soft tissue (LST), DXA may provide skewed results due to its method of indirectly calculating fat mass by subtracting it from the LST and/or body cell mass (BCM) that DXA actually measures. (wikipedia.org)
  • However, their mean body fat percentage, 14%, is well within what's considered a healthy range. (wikipedia.org)
  • level
  • it is currently understood that the level of expression for each isoform is dependent on factors such as sex, body mass index, and level of endurance exercise. (wikipedia.org)
  • Bodybuilders may compete at essential body fat range, in fact certified personal trainers will suggest them to keep that extremely low level of body fat only for the contest time. (wikipedia.org)
  • normal
  • normal people, who don't have so great a muscular mass, should stay into the fitness range in the table to be healthier. (wikipedia.org)
  • chest
  • Historically, the term mitral valve prolapse syndrome has been applied to MVP associated with palpitations, atypical chest pain, dyspnea on exertion, low body mass index, and electrocardiogram abnormalities in the setting of anxiety, syncope, low blood pressure, and other signs suggestive of autonomic nervous system dysfunction. (wikipedia.org)
  • intake
  • This study was conducted during World War II on a group of lean men, who restricted their calorie intake by 45% for 6 months and composed roughly 77% of their diet with carbohydrates. (wikipedia.org)
  • lower
  • A common cross-legged position is with the lower part of both legs folded towards the body, crossing each other at the ankle or calf, with both ankles on the floor, sometimes with the feet tucked under the knees or thighs. (wikipedia.org)
  • people
  • This results in taller people having a reported BMI that is uncharacteristically high, compared to their actual body fat levels. (wikipedia.org)
  • women
  • The percentage of essential body fat for women is greater than that for men, due to the demands of childbearing and other hormonal functions. (wikipedia.org)
  • physical
  • with a positive correlation associated with age and number of cigarettes smoked, and a negative correlation (decreased levels of physical inactivity) associated with years of formal education, body mass index, and increasing socioeconomic status. (wikipedia.org)
