Example Calculation

Let’s take an example:

  • Weight: 75 kg
  • Protein: 2 g per kg
  • Carbs: 4 g per kg
  • Fats: 1 g per kg

After entering these values:

  • Protein = 75 × 2 = 150 g
  • Carbs = 75 × 4 = 300 g
  • Fats = 75 × 1 = 75 g

This is the exact daily macro distribution you should aim for to meet your bodybuilding goals.
