What the result means
The result shows whether your protein intake is close to the target for training. Per-meal protein helps distribute intake more evenly across the day.
Daily protein target = body weight × protein factor. Protein per meal = daily target ÷ meals per day. Monthly target = daily target × 30.
People with kidney disease or medical restrictions should follow clinician guidance.
Example calculation
At 75 kg and 1.8 g/kg, the daily target is 135 g. Across four meals, that is about 34 g per meal.
Tips for better results
- Spread protein across meals.
- Use lean protein sources when calories are limited.
- Pair protein with progressive strength training.
