Frequently asked questions
- What is a typical macro split?
- A common starting point is 30% protein / 45% carbs / 25% fat, but athletes or those following specific diets (keto, high-protein) will differ.
- Why must percentages sum to 100?
- Macros account for all caloric intake, so the three percentages must total exactly 100% to produce accurate gram targets.
