Muscle gain & bulking
Best macros for bulking (without turning it into a dirty bulk)
Great bulking macros respect training volume: enough protein, enough carbs to perform, enough fat for taste and hormones—not random “40/40/20” worship.
Calories first, macros second
Surplus size drives weight trend; macros tune performance and adherence. Start from muscle calories.
Protein: anchor the bulk
Distribute protein across meals to support muscle repair; extremely low fat or carb extremes can hurt adherence or training quality.
Carbs: fuel for volume
Higher training loads often tolerate higher carb intakes; low-carb bulking works for some but can blunt performance for others.
Fats: calorie density + absorption
Fats make surpluses easier to hit and support fat-soluble vitamins—going too low long term can backfire.
Sample macro emphasis (illustrative % kcal)
Not prescriptions.
| Food / context | Typical serving | Approx. kcal |
|---|---|---|
| Performance bulk | conceptual | protein moderate-high, carbs higher |
| Low-appetite bulk | conceptual | fats slightly higher for density |
Values are rounded planning estimates—check labels for your brand.
Macro mistakes
- Chasing ratios while missing total calories.
- Avoiding carbs despite high training volume.
- All protein shakes, no fiber.
