Document Summary

Energy out: total energy expenditure (tee) include energy expended on maintaining. Basal metabolism: ~60% -75% of tee. Physical activity: ~15% - 30% of tee. Thermic effect of foods (tef) or diet-induced thermogenesis: ~10% of tee. Basal metabolism: the energy expended to maintain basic normal body functions, basal metabolic rate (bmr): the rate at which energy is used for basal metabolism. Affected by body weight, lean body mass, gender, growth rate, age, body temperature, thyroid hormone levels, and low-energy diets: resting metabolic rate (rmr) or resting energy expenditure (ree) Body energy : weight loss: if energy stores are not replenished, the amount of stored energy and hence, body weight will decrease. Glucose comes from glycogen breakdown and gluconeogenesis. Ketones are produced from fats if glucose is not enough: an energy deficit of 3500 kcalories results in the loss of a pound of body fat.
