How much fat endurance athletes need and which sources work best around training.
Why it matters
Fat helps endurance athletes cover total energy and protect health
- Fats support hormone function, nervous system health, and absorption of fat-soluble vitamins.
- They also help athletes stay full enough on lighter days and eat enough on heavy days.
Best sources
Choose fats that make meals better instead of heavier by accident
- Nuts, seeds, nut butter, olive oil, avocado, salmon, eggs, and dairy all do useful work.
- These foods are easiest to tolerate when paired with carbs and protein, not used alone.
Timing
High-fat meals are usually wrong right before key sessions
- Large fat loads can slow digestion and increase gut risk before harder or longer training.
- Move the richer foods farther from the session and keep pre-workout meals simpler.
