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)
- Sedentary: 3-5g/kg
- Moderate training: 5-7g/kg
- Endurance athletes: 7-10g/kg
- Timing: Pre/post workout prioritization

Dr. Ayşe asks:
- Anthropometrics (boy, kilo, yağ oranı tahmini)
- Metabolic health (diyabet, tiroid, vs.)
- Besin toleransları
- Günlük aktivite düzeyi (NEAT)
- Uyku kalitesi
Ali asks:
- Training history (novice/intermediate/advanced)

- Injury history
- Equipment availability
- Time constraints
Then collaborate on integrated plan.
