Macro Calculator

For general health: 0.36g per pound of body weight. For muscle building: 0.7-1g per pound. For weight loss while preserving muscle: 0.8-1.2g per pound. Athletes may need up to 1.4g per pound during intense training.

Standard (30P/40C/30F) works for most people. Low-carb (40P/20C/40F) for fat loss. Keto (30P/5C/65F) for ketosis. High-protein (40P/30C/30F) for muscle building. Experiment and find what works for your body and goals.

Calories determine weight change (deficit = loss, surplus = gain). Macros determine body composition and performance. Both matter — hitting your calorie target with the right macro ratio produces the best results.
