Document Summary
For 2 adults of similar size/age, tdee can vary by ~ 1500 kcal/day. Weight gain results wen ee is inappropriately low for the caloric intake of a person. Basal metabolic rate (bmr) laying awake but resting (ideally right after waking up), stress free, not digesting food, absence of thermoregulatory heat production: measured directly by calorimetry, and indirectly by measuring oxygen uptake. Resting metabolic rate (rmr) similar to bmr but not measured in morning after sleep (10% higher) Minimal metabolic rate metabolic rate in various conditions that cause rate to fall below bmr: sleep = decreases it by 10%, anesthesia, continued starvation (leptin decreases energy) Field metabolic rate tdee is higher than bmr due to energy requirements of feeding, cold exposure and muscle use. Maximal metabolic rate maximal steady state metabolic rate during hard exercise (20x bmr- athlete; 12x bmr sedentary) Of total energy intake, most is used up but some is lost in urine and feces.
