Honest limits
Calorie needs are estimates based on the Mifflin-St Jeor equation, accurate within roughly ±10% for most people. Individual metabolism, medical conditions, and medications change real needs. These are estimates only — consult a doctor or registered dietitian before starting any diet.
How to use the Calorie Calculator
- Enter your age, sex, height, and weight.
- Choose your activity level honestly — when in doubt, pick lower.
- Press Calculate calories — BMR, TDEE, and your three goal targets appear.

Example
30F, 165 cm, 65 kg, moderate → BMR ≈1,370, TDEE ≈2,124 cal/day — lose ≈1,624, maintain ≈2,124, gain ≈2,524.
