How it works

Estimates Total Daily Energy Expenditure (TDEE) — maintenance calories including your activity level.

Who it's for: Anyone setting calorie targets for weight loss, maintenance, or muscle gain using US customary units.

Derives BMR via Mifflin-St Jeor, then multiplies by an activity factor from 1.2 (sedentary) to 1.9 (very active).

Shows TDEE (maintenance) — calories to stay at current weight.

Includes quick targets for weight loss (−500 kcal) and weight gain (+500 kcal).

How to use

  1. Select Sex and enter Weight (lb), Height (in), and Age (years).
  2. Choose Activity honestly: desk job with no exercise = Sedentary; 3–5 workouts/week = Moderate.
  3. Read TDEE (maintenance) — your estimated daily calorie budget at current weight.
  4. For fat loss, note Weight loss (−500) — roughly one pound per week for many adults.
  5. For muscle gain, note Weight gain (+500) — a moderate surplus for lean bulking.
  6. Track weight for 2–3 weeks and adjust calories if the scale does not move as expected.

Good to know

  • The ±500 kcal rules are starting points — metabolic adaptation and NEAT changes may require fine-tuning.
  • Very active athletes may need custom factors beyond the highest preset.
