Optimal Carbohydrate Timing Strategies

• Pre-Workout (1-3 hours before): 30-60g complex carbs for sustained energy
• Intra-Workout (during exercise): 15-30g fast-acting carbs for sessions over 60 minutes
• Post-Workout (within 30 minutes): 0.5-1.2g per kg body weight for glycogen replenishment
• Evening Carbs: Complex carbs support sleep quality and recovery

Age-Specific Carbohydrate Requirements

Carbohydrate needs vary significantly across different life stages due to changing metabolic rates, activity levels, and physiological demands. The National Institute on Aging provides age-specific nutritional guidance showing how carbohydrate requirements evolve throughout life. Use our Age Calculator for precise age determination and combine with our Pregnancy Calculator for expecting mothers' changing nutritional needs.
