What to eat before a workout (without overthinking it)

Pre-workout eating has been over-engineered into a science project. The honest version: carbs are your muscles' preferred fuel, a bit of protein helps, and consistency beats optimisation.

The one principle

Working muscles run mostly on carbohydrate stored in the muscle and liver. For anything over an easy stroll, a meal containing carbs in the hours before training is the simplest performance upgrade available - more than any powder, patch or potion on the shelf.

Timing, in three tiers

Two to three hours out: a normal meal - carbs plus protein, easy on heavy fat and fibre, which digest slowly and can sit like a stone. Rice and chicken, pasta, oats, a sandwich. This is the ideal most people can hit for evening sessions.

Thirty to sixty minutes out: something small and mostly-carb - a banana, toast with honey, a few dates. Enough to top the tank without giving your stomach a project.

Training fasted (early mornings, before breakfast): fine for easy and moderate sessions. Fat loss is not meaningfully better fasted - the body balances over the whole day - so eat by preference and schedule, not myth. If the session is long or hard, eat first; the post-workout window matters less than the total day anyway.

Water, always

Arrive hydrated rather than chugging at the door - fluid is doing more jobs in there than the meal is. For sessions past the hour mark in heat, electrolytes start earning their place.

The honest caveats

Stomachs are personal: the runner who can eat oats at 6:00 and sprint at 6:30 exists next to the one who needs three clear hours. Experiment on easy days, lock in what works, and stop shopping for magic - real food covers almost everything, and showing up consistently outperforms any pre-workout ritual.
