How to Calculate Macro Split
What is Macro Split?
Allocates daily macronutrient targets (protein, carbs, fats) based on dietary goals and activity level. Optimizes nutrition for performance.
Step-by-Step Guide
- 1Determine caloric needs (BMR × activity factor)
- 2Allocate by goal: muscle gain 40/40/20 (P/C/F), fat loss 40/35/25, endurance 20/60/20
- 3Convert to grams: protein 4 cal/g, carbs 4 cal/g, fat 9 cal/g
- 4Adjust weekly based on progress
Worked Examples
Input
2000 cal/day, 40/30/30
Result
800/600/600
Common Mistakes to Avoid
- ✕Not accounting for activity when setting macros
- ✕Treating all carbs equally (timing and type matter)
