# TDEE Calculator

Calculate your Total Daily Energy Expenditure (TDEE) — the exact calories you need to maintain, lose, or gain weight. Compares WHO, NHS, and CDC physical activity guidelines.

## Quick answer

TDEE = BMR × activity multiplier. Sedentary (desk job, no exercise): ×1.2. Lightly active (1–3 workouts/week): ×1.375. Moderately active (3–5/week): ×1.55. Very active (daily hard training): ×1.9. To lose 0.5 kg/week, eat 550 kcal below TDEE. WHO recommends 150–300 min/week of moderate activity.

## Sources & Methodology

Total Daily Energy Expenditure multiplies BMR (Mifflin–St Jeor) by a physical activity level (PAL). PAL ranges follow the FAO/WHO/UNU human energy requirements report.
