Macro Timing Strategy
Pre-Workout (1-2 hours before)
High carbs, moderate protein, low fat
- • 30-40g fast-digesting carbs
- • 15-20g protein
- • <5g fat
Post-Workout (within 30 min)
High protein, high carbs, low fat
- • 25-35g fast-absorbing protein
- • 40-60g simple carbs
- • <5g fat
Evening/Night
High protein, low carbs, moderate fat
- • 20-30g slow-digesting protein
- • <20g complex carbs
- • 10-15g healthy fats

Macro Nutrition Science
PROTEIN
4 cal/g
- • Muscle protein synthesis
- • Tissue repair & recovery
- • Enzyme & hormone production
- • Immune system support
- • Satiety & appetite control
Daily Needs: 0.8-2.2g per kg body weight
CARBOHYDRATES
4 cal/g
- • Primary energy source
- • Brain & nervous system fuel
- • Muscle glycogen storage
- • Exercise performance
- • Protein-sparing effect
Daily Needs: 45-65% of total calories
FATS
9 cal/g
- • Hormone production
- • Fat-soluble vitamin absorption

- • Long-term energy storage
- • Satiety & meal satisfaction
Daily Needs: 20-35% of total calories
Goal-Specific Macro Guidelines
Weight Loss (Fat Loss)
Macro Distribution:
- • Protein: 30-40% (1.6-2.2g/kg)
- • Carbs: 25-35% (2-4g/kg)
- • Fats: 25-35% (0.8-1.2g/kg)
Key Strategies:
- • Higher protein preserves muscle
- • Moderate carbs around workouts
- • Caloric deficit of 300-500 calories
- • Focus on nutrient density
Muscle Gain (Lean Bulk)
Macro Distribution:
- • Protein: 25-30% (1.6-2.0g/kg)
- • Carbs: 40-50% (4-7g/kg)
- • Fats: 20-30% (1.0-1.5g/kg)
Key Strategies:
- • Adequate protein for synthesis
- • Higher carbs fuel workouts
- • Caloric surplus of 200-500 calories
- • Time carbs around training
Athletic Performance
Macro Distribution:
- • Protein: 20-25% (1.4-1.8g/kg)
- • Carbs: 50-60% (5-10g/kg)
- • Fats: 20-30% (1.0-2.0g/kg)
Key Strategies:
- • High carbs for glycogen
- • Strategic nutrient timing
- • Match calories to training load
- • Recovery nutrition priority
Carb Cycling Protocols
Weekly Carb Cycling Schedule
Monday - Low Day
0.5-1g/kg carbs
Tuesday - Low Day
0.5-1g/kg carbs
Wednesday - Moderate
2-3g/kg carbs
Thursday - Low Day
0.5-1g/kg carbs
Friday - Low Day
0.5-1g/kg carbs
Saturday - High Day

Carb Cycling Benefits
- Metabolic Flexibility: Improves ability to switch between fuel sources
- Fat Loss: Low carb days enhance fat oxidation
- Performance: High carb days fuel intense training
- Hormonal Balance: Prevents metabolic adaptation
- Psychological: Reduces deprivation feelings
Implementation Tips:
- • Schedule high days on hardest training days
- • Keep protein and fat consistent
- • Monitor energy and performance
- • Adjust based on individual response
