Basal Metabolic Rate

Question

Basal metabolic rate
A)reflects the rate that nutrients are metabolized when one is exercising.
B)is controlled by the ratio of insulin to glucagon.
C)remains constant throughout the day.
D)is the body's entire Calorie requirement.
E)is the amount of energy consumed by the body in the basal state.

Accepted Answer

Basal metabolic rate (BMR) is the amount of energy consumed by the body in the basal state, which is when the body is at rest, awake, and in a fasted state, and without any physical or mental stress. BMR is influenced by factors such as body size, body composition, age, gender, and genetics, and typically accounts for about 60-75% of the body's entire calorie requirement. BMR can vary slightly throughout the day due to factors such as digestion, physical activity, and environmental temperature, but it generally remains relatively stable. BMR is not directly controlled by the insulin-glucagon ratio or the rate of nutrient metabolism during exercise, although these factors can indirectly affect BMR.
