# Nutrition

Daily calorie needs, or total daily energy expenditure, are usually estimated from the basal metabolic rate (BMR), the energy a body uses at rest, multiplied by an activity factor. Protein, carbohydrate and fat targets and calorie deficits build on that figure. Equations such as Mifflin-St Jeor predict averages for groups, so your own needs can differ.
