Estimate daily calorie intake associated with weight maintenance.
What Is Maintenance Calories?
Maintenance calories are the approximate daily calories that would match estimated energy expenditure and therefore tend to maintain body weight over time.
The estimate is useful as a planning baseline before choosing a calorie deficit or surplus.
Formula / Method Used
Maintenance calories are estimated from TDEE using the Mifflin-St Jeor BMR equation and an activity multiplier.
