Answer:
BMR ( Basal metabolic rate)
BMR may be defined as the energy required for the proper functioning of body at rest. This is the amount of energy required from the basal metabolism of the body. BMR is always less than TDEE. BMR of the body remains same in case of weight gain or weight loss.
TDEE ( Total daily energy expenditure)
TDEE may be defined as the daily energy expenditure of the body. The amount of energy requires from the physical activity and basal metabolism of the body. TDEE is always higher than the BMR. TDEE of the body may be affected by the weight gain or weight loss.
