Macro calculator

Calories and macros for your goal: protein first (it protects muscle and keeps you full), a healthy share of fat, and carbs for the rest. The same numbers the BindTrue app gives its members.

Your result

1,500 calories a day

Your maintenance is about 2,050 kcal a day.

  • Protein150 g40% · 600 kcal · at least 110 g
  • Fat45 g27% · 405 kcal
  • Carbs125 g33% · 500 kcal

That is about 50 g of protein per meal over 3 meals. Water: about 2.2 L a day, plus 0.5 L on workout days.

How your macros are calculated

  1. Calories: your TDEE (Mifflin-St Jeor × activity), then −25% to lose fat or +8% to build muscle. The fat-loss target never goes below 1,300 kcal for women or 1,600 for men.
  2. Protein: 2.2 g per kg of body weight (about 1 g per lb), and at least 1.6 g per kg. Above a BMI of 25 it is based on the weight you would have at a BMI of 25.
  3. Fat: 27% of your calories, inside the 20–35% range of the Dietary Reference Intakes.
  4. Carbs: the calories that are left (4 kcal per gram; protein 4, fat 9).

Do the numbers have to be exact?

No. Hit your calories and your protein most days; fat and carbs can swing from day to day without changing much. A simple way to get close without weighing food: at each meal fill half the plate with vegetables, a quarter with protein (palm-sized) and a quarter with carbs (fist-sized), plus a thumb of fat.
