# TDEE

TDEE (total daily energy expenditure) is the total energy you use in a day: resting metabolism plus activity and digesting food.

It is usually estimated from a resting-rate equation such as Mifflin-St Jeor times an activity factor, then adjusted against your real weight trend.

Also called: Total daily energy expenditure, Maintenance calories.
