What Are Maintenance Calories?
Maintenance calories (also called TDEE — Total Daily Energy Expenditure) are the exact number of calories you need to eat each day to keep your body weight stable.
Eat at maintenance → weight stays the same. Eat below maintenance → weight decreases. Eat above maintenance → weight increases.
It's as simple as that — at least in principle.
Why Maintenance Matters
Most people go from one diet to another without spending time at maintenance. This is a problem:
- You don't know your real TDEE. Calculators give estimates. Spending 2–3 weeks eating at calculated maintenance and observing actual weight trends calibrates your real TDEE.
- Maintenance eating is a skill. Most people either undereat or overeat — eating at exactly the right amount requires practice and awareness.
- Maintenance breaks help during dieting. Taking 1–2 weeks at maintenance every 4–6 weeks during a cutting phase partially reverses metabolic adaptation, making the subsequent deficit more effective.
How to Find Your True Maintenance
Option 1: Use the calculator Enter your measurements and activity level. Your TDEE is the maintenance estimate.
Option 2: Track and adjust Eat your calculated TDEE for 3 weeks. Weigh yourself daily, take a weekly average weight. - If weight is slowly increasing → reduce by 150–200 calories - If weight is slowly decreasing → increase by 150–200 calories - If weight is stable → you've found your maintenance
Option 2 is more accurate because it accounts for individual metabolic variation.
Maintenance for Different Goals
Body recomposition: Some people want to lose fat and gain muscle simultaneously without changing their weight. This "body recomp" approach works best for beginners or people returning after a break — eating at maintenance with high protein and resistance training.
Weight maintenance post-diet: After reaching a goal weight, many people struggle to maintain because they've been in a mindset of restriction. Transitioning to maintenance gradually (adding 100–200 calories per week) prevents rebounding.
Weight stability during life events: Traveling, holidays, or stressful periods are often easier to manage if you're not actively cutting — maintaining weight is a realistic, lower-pressure goal.
