The Energy Equation: Science of Outdoor Nutrition
Macronutrient Ratios for Activity
| Activity | Carb:Fats:Protein | Calories/Hour | Hydration |
|---|---|---|---|
| Hiking (Moderate) | 60:25:15 | 200-250 | 500ml water + electrolytes |
| Climbing/Tech Terrain | 70:20:10 | 300-350 | 750ml + sodium |
| Cold Weather | 50:40:10 | 350-400 | Warm fluids |
Key Insight: Carbs = immediate energy, Fats = sustained fuel, Protein = muscle repair.
