How to use this calculator
- Enter sex, age, height, weight and activity level.
- Read your TDEE (maintenance calories) plus mild loss/gain targets.
How it works
TDEE = BMR × an activity multiplier (1.2 sedentary → 1.9 very active). It's the calories to maintain your weight.
Worked example
BMR 1,780, moderate activity. TDEE ≈ 1,780 × 1.55 = 2,759 kcal/day.
