levels in bloodstream, hormones, etc. Usually sets in 4-6 hours
Total energy expenditure— Ans: total amount of energy used in
the body each day
*it consists of three components
-basal metabolism
-energy needed for physical activity
-energy needed to "process" the food
basal metabolism— Ans: energy expended to maintain an
awake, resting body that is NOT digesting food
-includes all essential metabolic reactions and life sustaining
functions to keep you alive/breathing etc
***Does NOT include digestion and absorption of food
60%-75% of total energy expenditure— Ans: Basal Metabolism

metabolism

thyroxine— Ans: a hormone excreted by the thyroid gland;
directly controls basalmetabolism
More thyroxine secreted— Ans: higher BMR
less thyroxine secreted— Ans: lower BMR
BMR is lowest during— Ans: Sleep
Minerals needed to make thyroxine— Ans: Iodine
Iodine deficiency in the body— Ans: -thyroid gland can become
enlarged in attempt to trap any that is circulating
enlargement of thyroid gland— Ans: Goiter
age and growth— Ans: BMR high in infants up to 2 years old &

during adolescents
Taller person— Ans: higher BMR
Higher lean body mass— Ans: increases BMR
Guru01 - Stuvia
Gender BMR difference— Ans: Males BMR > Females BMR
Extreme temperature changes— Ans: increase BMR
False— Ans: Food can increase BMR (true or false)
As someone gets older— Ans: BMR decreases
physical activity— Ans: 15%-30% total energy expenditure
Thermic effect of food (TEF)— Ans: energy required for the
digestion of food and absorption, metabolism and storage of
nutrients
10% of energy intake— Ans: TEF (can vary depending on
amounts of food and types of nutrients consumed)
*EX: bigger the meal = higher TEF
High fat meals— Ans: Yield lower TEF. Why?
-dietary fat can be stored and used more efficiently
Premise behind weight gain -> Excess calories— Ans: consume
more than you expend -> energy will be stored. -small amounts ->
glycogen in liver & skeletal muscles
-most -> TGs (fat) in adipocytes "fat cells"
