A useful starting point, not a perfect prediction. Your activity estimate and real-world progress matter more than a single exact number.

How your targets are calculated

1. Estimate resting energy. The Mifflin–St Jeor equation uses your weight, height, age and sex to estimate resting calorie needs.

Resting kcal = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + sex constant
Sex constant: +5 for male; −161 for female.

2. Account for activity. Resting calories × activity multiplier = estimated maintenance calories. Categories are rough starting assumptions; exercise sessions alone do not determine your activity level. Fine-tuning overrides the category's number.

3. Adjust for your goal. Maintain / recomp uses maintenance, fat loss uses 15% below maintenance, and muscle gain uses 10% above. These are this calculator's starting settings, not universal prescriptions or guarantees.

4. Allocate macros. Protein defaults to 2 g per kg of total body weight; fat defaults to 25% of target calories. Carbs use the remaining calories. Protein and carbs provide 4 kcal per gram, fat 9. Macro grams are rounded, so their calorie total can differ slightly from the displayed target.

Body fat is optional. Lean mass = body weight × (1 − body fat % / 100). It is shown for context only; this version uses Mifflin–St Jeor for calories regardless of body fat.
