Energy intake. Medical search. Frequent questions

Energy expenditure refers to the amount of energy an individual uses to maintain essential body functions (respiration, circulation, digestion) and as a result of physical activity. (springer.com)
Total daily energy expenditure is determined by resting or basal metabolic rate (BMR), food-induced thermogenesis, and energy expended as a result of physical activity. (springer.com)
BMR accounts for typically 65-75% of total energy expenditure. (springer.com)
Food-induced thermogenesis refers to the increase in energy expenditure following the ingestion of food. (springer.com)
In industrialised countries, most people regulate their energy expenditure poorly. (hindawi.com)
Individual energy expenditure may differ up to 20-fold between resting conditions and high physical activity, but such differences have until now been weakly correlated to energy intake at subsequent meals [ 1 ]. (hindawi.com)
We studied the effect of meal frequency on human energy expenditure (EE) and its components. (cambridge.org)
