How to use it

  1. 1Choose your sex and unit system, then enter age, height, and weight.
  2. 2Select your activity level.
  3. 3Read your BMR, maintenance calories, and the calorie targets for each weight goal.
  4. 4Scroll down for a suggested macronutrient breakdown at maintenance.

Example

At a maintenance level of 2,633 kcal/day (built on a BMR of 1,699), a gradual weight-loss target would be about 2,370 kcal/day (a 10% deficit) — enough of a gap to lose weight steadily without an extreme cut. At maintenance, a balanced 30/40/30 split works out to roughly 197g protein, 263g carbs, and 88g fat per day.

How it works

Your maintenance calories are your TDEE (BMR × activity level), shown alongside your resting BMR so you can see how much activity level actually matters. From there, weight-loss goals subtract 10-20% and weight-gain goals add 10-20%, roughly corresponding to a gradual or faster pace — 1% of body weight lost or gained per week is a commonly cited sustainable rate, not a strict rule. The suggested macro breakdown splits your maintenance calories 30% protein / 40% carbs / 30% fat, a reasonable general-purpose starting point you can adjust to taste.
