Maintenance Calories
The calorie intake that tends to keep body weight stable (often close to TDEE).
Definition
Maintenance calories are the approximate number of calories you can eat per day while keeping body weight stable over time. For many people, maintenance is close to TDEE, though real-world maintenance also depends on consistency and measurement accuracy.
Example
If your weight stays flat for several weeks at 2,100 calories/day, that may be your maintenance.
