Basal Metabolic Rate

Basal Metabolic Rate, or BMR, is the number of calories needed for basic bodily functions essential for life.

BMR is not the same as weight maintenance calories, it is a number smaller than weight maintenance calories, typically by a few hundred calories.

Please see Planning Weight & Calories article for more information about the three major components of energy expenditure (BMR, thermic effect of food, and physical activity).
