Macro Calculator

Hit your calorie target with the right split of protein, carbs and fats.

Our default split

  • Protein 35% — preserves muscle in a deficit and keeps you full
  • Carbs 35% — fuels training and recovery
  • Fats 30% — supports hormones and satiety

Why macros matter

Total calories drive weight change, but macros decide whether you lose fat or muscle, how energetic you feel, and how easy the diet is to stick to.

About you

Your day-to-day movement — workouts are added separately below for accuracy.

Your training

We use METs (metabolic equivalents) for your bodyweight & intensity to estimate true calorie burn — much more accurate than a single activity multiplier.
