Maintenance Calories Calculator: Your Weight-Stable Calorie Target
A 30-year-old male, 5'10", 175 lbs with moderate activity has maintenance calories of approximately 2,728 per day. Eating at this level will keep your weight stable. Your maintenance calories = your TDEE (Total Daily Energy Expenditure).

What Maintenance Calories Include
| Component | % of Total | Description |
|---|---|---|
| BMR | 60-70% | Calories for basic organ function at rest |
| Physical Activity | 15-30% | Exercise + daily movement (NEAT) |
| Thermic Effect of Food | 8-15% | Calories burned digesting food |
| Adaptive Thermogenesis | Variable | Body's metabolic adjustment to environment |
Finding Your True Maintenance
The calculator provides an estimate. To find your actual maintenance calories:
1. Eat at the calculated amount for 2 weeks
2. Weigh yourself daily at the same time (morning, after bathroom, before food)
3. Average each week's weigh-ins
4. If average weight stays within 0.5 lbs: that is your true maintenance
5. If weight trends up: reduce by 100 cal and repeat
6. If weight trends down: increase by 100 cal and repeat
When to Eat at Maintenance
- Diet breaks: 1-2 weeks at maintenance every 8-12 weeks of dieting reduces metabolic adaptation
- After a diet phase: Reverse diet (gradually increase calories by 100/week) back to maintenance
- Body recomposition: Eat at maintenance with high protein (1g/lb) and strength train to simultaneously lose fat and gain muscle (best for beginners)
- Performance phases: Athletes maintaining weight class or competition weight

Frequently Asked Questions
What are maintenance calories?
Maintenance calories are the total daily calorie intake at which your body weight stays stable over time. This number equals your Total Daily Energy Expenditure (TDEE) — the sum of your Basal Metabolic Rate, physical activity, and the thermic effect of food. Eating above maintenance causes weight gain; eating below causes weight loss.
How do I know if I am eating at maintenance?
Track your weight daily for 2-3 weeks while eating a consistent calorie amount. Average each week's weigh-ins (to smooth out daily fluctuations from water, sodium, etc.). If weekly averages stay within 0.5 lbs of each other, you are at maintenance. Weight stability over time, not day-to-day readings, is the indicator.
Do maintenance calories change?
Yes. Maintenance calories change with weight (lighter bodies need fewer calories), age (BMR declines with age), activity level changes, muscle mass changes, hormonal fluctuations, and metabolic adaptation from dieting. Recalculate every 10-15 lbs of weight change or every 2-3 months.
Should I eat at maintenance on rest days?
Most people should eat roughly the same amount daily rather than cycling calories between training and rest days. The simplest approach: calculate a daily average based on your weekly activity level and eat that amount every day. Advanced athletes may benefit from calorie cycling (more on training days, less on rest days), but the difference is marginal for most people.
What happens if I eat exactly at maintenance?
Your body weight stays approximately stable. You will not gain or lose significant fat or muscle (assuming adequate protein and training stimulus). Eating at maintenance with strength training and high protein intake can produce body recomposition — simultaneously losing fat and building muscle — especially in beginners and people returning to training.
