Calorie Maintenance
Definition
Caloric maintenance (or maintenance calories) is the calorie intake at which your body weight stays stable over time. It equals your TDEE — Total Daily Energy Expenditure.
💡 Without knowing your maintenance, you can't plan a cut, a bulk, or a recomp. It's the foundation of any nutritional strategy.
What's inside maintenance?
Maintenance covers 4 components:
- BMR (60-70%): basal metabolic rate at complete rest
- TEF (10%): thermic effect of food (digestion)
- EAT (5-15%): exercise activity thermogenesis
- NEAT (15-30%): non-exercise activity thermogenesis (daily movement)
How to calculate your maintenance
| Method | Accuracy |
|---|---|
| Mifflin-St Jeor formula × activity factor | ±10-15% |
| Empirical (track 2-3 weeks at constant intake) | ±2-5% |
| DEXA + indirect calorimetry | ±1-2% |
⚠️ Online calculators give an estimate, not your real number. Validate empirically.
Maintenance shifts over time
- ✅ Lose weight → maintenance drops (less mass to fuel)
- ✅ Gain muscle → maintenance rises
- ✅ Increase activity → maintenance rises
- ✅ Long deficit → metabolic adaptation, maintenance can drop 5-10%
- ✅ Aging → 1-2% drop per decade
Strategic uses of maintenance
Maintenance phases are powerful tools:
- End of cut: 4-8 weeks at maintenance to stabilize
- Diet break: 1-2 weeks during a long cut to restore hormones
- Reverse diet: progressive return to maintenance after a cut
- Recomposition: maintenance + heavy training = muscle up + fat down
Common mistakes
- ❌ Trusting calculators 100%
- ❌ Not adjusting after weight changes
- ❌ Believing maintenance is fixed for life
- ❌ Skipping maintenance phases between cut/bulk cycles
Key takeaways
Caloric maintenance is your nutritional zero point. Validate it empirically over 2-3 weeks, recalibrate every 2-3 months. Master it, and you control your body composition.
