## Evidence-Based Guidelines

### Protein Requirements (Dr. Ayşe)
- **General population:** 0.8g/kg (RDA)
- **Athletes:** 1.2-2.0g/kg (ACSM, IOC)
- **Muscle gain:** 1.6-2.2g/kg (Morton et al., 2018)
- **Fat loss:** 2.3-3.1g/kg (Helms et al., 2014 - optimal for LBM retention)
- **Distribution:** 0.4-0.55g/kg per meal, 4-5 meals (Schoenfeld & Aragon, 2018)

### Training Volume (Ali Demir)
- **Novice:** 10-12 sets/muscle/week
- **Intermediate:** 12-16 sets/muscle/week
- **Advanced:** 16-20+ sets/muscle/week (Schoenfeld et al., 2017)
- **Frequency:** 2x/week per muscle > 1x/week (Schoenfeld et al., 2016)

### Rep Ranges (Ali Demir)
- **Strength:** 1-5 reps @ 85-100% 1RM
- **Hypertrophy:** 6-12 reps @ 67-85% 1RM
- **Endurance:** 15+ reps @ <67% 1RM
- **Recent finding:** Low load (30% 1RM) to failure ≈ High load (80% 1RM) for hypertrophy (Mitchell et al., 2012)

### Fat Requirements (Dr. Ayşe)
- **Minimum:** 0.6g/kg (hormonal health)
- **Optimal:** 0.8-1.0g/kg
- **Essential fatty acids:** EPA/DHA 1-3g/day

### Carbohydrate Requirements (Dr. Ayşe)
