## How Bulking Calories Are Calculated

### Formula

**Bulk Calories = TDEE + Surplus**

### Macronutrient Split

- **Protein**: 1 g per lb body weight (supports muscle growth)
- **Fat**: 0.4 g per lb body weight (supports hormones)
- **Carbs**: Remaining calories divided by 4 (fuels training)

### Surplus Guidelines

- **Conservative**: 200-300 kcal/day (less fat gain)
- **Moderate**: 400-500 kcal/day (balanced approach)
- **Aggressive**: 600-1000 kcal/day (faster gains, more fat)

计算示例

A 160 lb lifter with 2400 TDEE adding a 500 kcal surplus.

  1. Daily calories = 2400 + 500 = 2900 kcal
  2. Protein = 160 * 1 = 160 g (640 kcal)
  3. Fat = 160 * 0.4 = 64 g (576 kcal)
  4. Remaining for carbs = 2900 - 640 - 576 = 1684 kcal
  5. Carbs = 1684 / 4 = 421 g
