  2. Adjust the intensity, frequency, or nutrition target to match your goal.

What the result means

Higher training intensity and fat-loss phases usually need more protein to support recovery and lean mass.

Daily protein = body weight × protein factor. Protein per meal = daily protein ÷ meals per day.

Protein needs vary by health status, calorie intake, and training load.

Example calculation

A 70 kg lifter using 1.8 g/kg needs 126 g protein per day.

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.
