One of the biggest mistakes athletes make?

Eating the right foods… at the wrong time.

Your pre-training nutrition can directly impact:
• energy levels
• performance output
• digestion
• recovery
• how strong and fast you feel during sessions

The closer you get to training, the simpler and easier to digest your carbs should become.

This guide breaks down exactly what to eat based on how far out you are from your workout so you can fuel smarter instead of guessing 👇

Travel doesn’t have to turn into a week of feeling bloated, under-fueled, and completely off track.

Most people struggle while traveling because they rely on convenience foods that are low in protein, low in fiber, and easy to overeat.

A few simple swaps can make a massive difference:
• prioritize easy protein sources
• pack snacks ahead of time
• stay on top of hydration + electrolytes
• keep fiber intake consistent
• include healthy fats in moderation

You do NOT need to eat perfectly while traveling.

You just need better systems.

These are some of my favorite realistic travel nutrition hacks that help support fat loss, energy, digestion, and recovery without overcomplicating things.
