AP PSYCHOLOGY

Detailed explanation-1: -The BMR refers to the amount of energy your body needs to maintain homeostasis. Your BMR is largely determined by your total lean mass, especially muscle mass, because lean mass requires a lot of energy to maintain. Anything that reduces lean mass will reduce your BMR.

Detailed explanation-2: -Basal metabolic rate (BMR) is often used interchangeably with resting metabolic rate (RMR). While BMR is a minimum number of calories required for basic functions at rest, RMR-also called resting energy expenditure (REE)-is the number of calories that your body burns while it’s at rest.

Detailed explanation-3: -Resting energy expenditure (REE) represents energy expenditure while a person lies quietly awake in an interprandial state; under these conditions, approximately 1 kcal/kg body weight is consumed/hour in healthy adults.

Detailed explanation-4: -The basal metabolic rate (BMR) is the rate of energy expenditure of a person at rest; it eliminates the variable effect of physical activity. The BMR accounts for approximately 60% of the daily energy expenditure.

Detailed explanation-5: -The basal metabolic rate (BMR) is the amount of energy that is expended at rest in a neutral environment after the digestive system has been inactive for about 12 hours. It is the rate of one’s metabolism when waking in the morning after “fasting” during sleep.
