Bulking vs Cutting: How Your Protein Intake Should Change
Bulking and cutting are two sides of the same cycle — but your protein strategy shifts slightly for each.
Bulking (Gaining Muscle)
Goal: Calorie surplus + muscle growth
Protein: 1.6-2.0g per kg of body weight Calories: Maintenance + 300-500
The extra calories come from carbs and fats, not from excessive protein. More than 2g/kg doesn’t build more muscle — it just turns into expensive fuel.
Sample for a 70kg person:
- 120-140g protein
- 2500-2700 calories
- Carbs: 300-350g
- Fats: 60-70g
Best foods: whole eggs, full-fat milk, paneer, peanuts, banana shakes, ghee in daal
Cutting (Losing Fat)
Goal: Calorie deficit while preserving muscle
Protein: 2.0-2.4g per kg of body weight Calories: Maintenance - 300-500
Protein goes up during a cut — it keeps you full, preserves muscle, and has a higher thermic effect (burns more calories during digestion).
Sample for a 70kg person:
- 150-170g protein
- 1800-2000 calories
- Carbs: 150-180g
- Fats: 40-50g
Best foods: egg whites, soya chunks, whey protein, grilled chicken/fish, low-fat paneer, curd
Key Differences
| Bulking | Cutting | |
|---|---|---|
| Protein | 1.6-2.0g/kg | 2.0-2.4g/kg |
| Carbs | High | Moderate |
| Fats | Moderate | Low-moderate |
| Calorie surplus | +300-500 | -300-500 |
| Meal frequency | 3-4 meals | 4-5 meals (to manage hunger) |
The Golden Rule
Never cut protein to save calories. Drop carbs and fats first. Protein is the last macro you reduce — it protects your muscle while you lose fat.
