Question

out of basal metabolic rate, thermic effect of food, and physical activity is the most most variable (and the most amenable to change) to your total energy expenditure?

Answer 1

Physical activity is the most variable and amenable to change component of total energy expenditure (TEE) among basal metabolic rate (BMR), thermic effect of food (TEF), and physical activity.

Step-by-step explanation:

The most variable component of total energy expenditure (TEE) among basal metabolic rate (BMR), thermic effect of food (TEF), and physical activity is physical activity. Physical activity is the most amenable to change and can have a significant impact on TEE. BMR is the amount of energy your body needs at rest, while TEF is the energy used during digestion.
