How the macro calculation works
Calories drive the overall direction of weight change. Protein supports muscle retention and growth, dietary fat supports normal nutrition, and carbohydrates fill the remaining energy budget. The exact split is less important than a calorie target and protein intake you can sustain.
Adjusting your macro plan
Keep the plan steady long enough to observe a trend—usually two to three weeks. If progress is not moving in the intended direction, adjust calories modestly and recalculate rather than constantly changing every macro.
Frequently asked questions
- How are macros calculated?
- Protein and carbohydrate each provide about 4 calories per gram; fat provides about 9. This tool reserves protein and fat first, then assigns remaining calories to carbohydrates.
- Are the targets exact?
- No. They are a practical starting point. Track your trend and adjust calories before making large macro changes.
