Maintenance Calories: Your Exact Daily Number
Instant Answer
Maintenance calories equal your TDEE — typically 1,600–3,200 for adults depending on size and activity. At maintenance, your weight stays stable (±1 kg from daily fluctuations). This is the foundation for any goal: subtract for fat loss, add for muscle gain.

What Are Maintenance Calories?
Maintenance calories are the exact number of calories where your body weight remains stable over time — neither gaining nor losing. This number equals your Total Daily Energy Expenditure (TDEE), the sum of your Basal Metabolic Rate (calories burned at rest), the thermic effect of food (energy used digesting food, ~10% of intake), exercise activity thermogenesis (planned exercise), and non-exercise activity thermogenesis (NEAT — fidgeting, walking, standing, daily movement). Your maintenance level is the anchor point for all nutritional planning. To lose fat, you eat below it. To build muscle, you eat above it. To maintain your physique, you eat at it. Knowing this number removes all guesswork from your nutrition.
How to Calculate Your Maintenance Calories
The most accurate way to find maintenance is empirical: track your food intake and weight for 2–3 weeks. If your weight is stable (same 7-day average), your current intake is your maintenance. For a faster estimate, use our TDEE calculator with the Mifflin-St Jeor equation: Men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 5. Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161. Multiply BMR by activity factor: 1.2 (sedentary), 1.375 (light exercise), 1.55 (moderate), 1.725 (very active). The calculator provides an estimate — fine-tune it over 2–3 weeks by monitoring scale trends.
Maintenance Calories by Body Weight
Approximate maintenance ranges for moderately active adults (activity factor 1.55): 55 kg woman, 165 cm, age 30: ~1,850 calories. 65 kg woman, 170 cm, age 30: ~2,050 calories. 70 kg man, 175 cm, age 30: ~2,450 calories. 80 kg man, 178 cm, age 30: ~2,650 calories. 90 kg man, 183 cm, age 30: ~2,850 calories. 100 kg man, 185 cm, age 30: ~3,050 calories. These are estimates — actual maintenance varies based on genetics, NEAT levels (some people naturally fidget and move more), hormonal status, and metabolic history (those who've dieted heavily may have lower maintenance than predicted). Individual variation of ±200 calories is common.
Why Maintenance Matters After Dieting
After a fat loss phase, transitioning to maintenance is arguably more important than the diet itself. Most diet failures happen not during the deficit, but in the weeks after — when people either continue restricting (leading to burnout and bingeing) or immediately return to pre-diet eating (causing rapid fat regain). The solution is reverse dieting: gradually increasing calories by 100–150 per week until reaching your new maintenance level. This allows your metabolism to upregulate, hunger hormones (leptin, ghrelin) to normalize, and training performance to recover. Spend a minimum of 4–8 weeks at maintenance before starting another deficit or surplus. This 'diet break' improves long-term results dramatically.
Eating at Maintenance for Body Recomposition
Maintenance calories aren't just a transitional phase — they're also the foundation for body recomposition (simultaneously losing fat and gaining muscle). While this process is slower than dedicated cutting or bulking, it's ideal for beginners (first 6–12 months of training), those returning to exercise after a break, individuals at moderate body fat (15–25% for men, 22–32% for women), and anyone who prefers a less restrictive approach. To recomp at maintenance: eat at TDEE, set protein to 1.8–2.2 g/kg, strength train 3–5 days per week with progressive overload, sleep 7–9 hours, and be patient — visible changes take 2–4 months. Track body fat percentage and waist circumference rather than scale weight.
Factors That Change Your Maintenance Calories
Your maintenance isn't a fixed number — it shifts based on several factors. Weight change: for every 1 kg lost, TDEE drops ~15–20 calories. Aging: metabolism decreases ~1–2% per decade after 30. Seasonal changes: NEAT increases in summer (more outdoor activity) and decreases in winter. Stress and sleep: chronic stress and poor sleep can reduce maintenance by 5–10% through hormonal changes. Menstrual cycle: women's TDEE fluctuates ~100–300 calories across the cycle (higher in luteal phase). Exercise consistency: missing training sessions reduces TDEE more than most people realize — 3 missed sessions can drop weekly expenditure by 500–1,000 calories. Recalculate quarterly using our TDEE calculator, and adjust based on real-world weight trends.
