# Nutrition for Athletes

## When to use this skill
Use when the user says things like:
- "How should I fuel for a workout?"
- "I need a pre-training meal plan."
- "What should I eat after training?"
- "How do I hydrate for hot days of training?"
- "How can I adjust macros during different training phases?"


## Core Philosophy

Nutrition is training's partner — it provides the fuel for performance and the raw materials
for recovery and adaptation. An athlete can train perfectly and still underperform if
nutrition does not support the demands placed on the body. Sports nutrition is not about
restriction but about intentional fueling — giving the body what it needs, when it needs it,
in the amounts that support both performance and health.

## Key Techniques

- **Energy availability**: Ensure caloric intake meets the demands of training volume and intensity.
- **Macronutrient periodization**: Adjust carbohydrate, protein, and fat intake based on training phase.
- **Pre-training fueling**: Consume easily digestible carbohydrates 1-3 hours before training.
- **Post-training recovery**: Combine protein (20-40g) and carbohydrates within 1-2 hours of training.
- **Hydration strategy**: Develop individualized hydration plans based on sweat rate and conditions.
- **Competition nutrition**: Practice competition-day nutrition in training before using it in events.

## Best Practices

1. Never try new foods or supplements on competition day. Practice all nutrition strategies in training.
2. Prioritize whole foods over supplements. Supplements supplement good nutrition — they do not replace it.
3. Eat enough. Under-fueling is more common than overeating among serious athletes.
4. Time carbohydrate intake around training — before for fuel, after for recovery.
5. Consume protein throughout the day in regular intervals rather than in one or two large meals.
6. Monitor hydration by tracking urine color (pale yellow is optimal) and body weight changes.
7. Individualize. What works for one athlete may not work for another — experiment and track.

## Common Patterns

- **Training day template**: Pre-training meal → intra-training hydration → post-training recovery meal.
- **Carb loading**: Increasing carbohydrate intake 2-3 days before endurance competition.
- **Weight-class management**: Gradual weight adjustment through nutrition over weeks, not rapid cuts.
- **Travel nutrition**: Planning portable, familiar food options for competition travel.

## Anti-Patterns

- Severely restricting calories during heavy training periods, causing relative energy deficiency.
- Relying on supplements instead of addressing fundamental dietary patterns.
- Eliminating entire food groups (carbohydrates, fats) without medical or evidence-based reason.
- Using dehydration for weight management — this impairs performance and risks health.
