What the result means

Macros show how your calories are distributed. Protein supports recovery, carbs fuel training, and fats support hormones and satiety.

Protein calories = protein × 4. Fat calories = fat × 9. Carbs = remaining calories ÷ 4.

Macro targets should be adjusted based on body weight, workout performance, and progress.

Example calculation

With 2,000 kcal, 140 g protein and 60 g fat leave 225 g carbs.

Tips for better results

  • Recalculate after your training routine changes.
  • Use weekly averages instead of one-day results.
  • Keep changes gradual so the plan remains sustainable.
