What to Eat Before a Workout (Without Overcomplicating It)
Knowing what to eat before a workout shouldn't require a sports science degree.
For most people training a few times a week around a busy life, a handful of simple principles cover almost everything you actually need to know, and get it right more often than the complicated advice does.
Why Pre-Workout Nutrition Matters
What you eat before a workout affects how the session actually feels.
Whether you've got the energy to push through it, or you're running on empty by the halfway point.
This matters most for longer or harder sessions, less so for a light, short workout, which is worth knowing before you overthink a 30-minute session that doesn't need much preparation at all.
What to Eat Before a Workout: The Practical Rules
For longer or harder training sessions, a useful starting point is roughly 0.75g of carbohydrate per kg of bodyweight, eaten 60-90 minutes before you train.
That's enough time for it to digest properly without still sitting heavy in your stomach when you start.
In terms of what to eat before a workout specifically, simple, easy-to-digest carbohydrates work best:
A banana
Bagel thins with jam or honey
Toast with honey
A small bowl of low-fibre cereal
Why Fat Should Be Kept Low Pre-Workout
One detail that trips a lot of people up: fat slows digestion.
This means high-carb, high-fat combinations, things like pastries, croissants, most baked goods, aren't ideal choices for what to eat before a workout, even though they seem like a reasonable "carb-heavy" option.
They'll likely still be sitting in your stomach when you start training, which can make a session feel worse, not better.
Should You Train Fasted?
Some people train fasted, particularly for lighter sessions, without any noticeable downside.
For harder or longer sessions specifically, though, having something beforehand tends to make a real difference to how the session feels and how well you can push through it.
If you're unsure, it's worth simply testing both approaches on similar sessions and noticing the difference for yourself.
What About Timing If You're Short on Time?
Not everyone has a clean 60-90 minute window before training, which is understandable for most busy schedules.
If you're training sooner than that, lean towards something smaller and even easier to digest (half a banana, a small amount of honey) rather than skipping it altogether or eating a full meal too close to your session.
The High/Low Method: Matching Your Whole Day to Training
What to eat before a workout is really just one piece of a bigger idea: matching your intake to what your day actually needs. Training days can reasonably carry a bit more food than rest days.
I call this the "High/Low" approach, and it means you're not eating identically on a heavy training day and a completely sedentary one.
Common Questions About Pre-Workout Nutrition
What should I eat before a workout if I'm training first thing in the morning? Something small and fast-digesting, half a banana or a small amount of honey on toast, eaten as early as your schedule allows before training.
Do I need a specific pre-workout supplement? No. Food covers what most people need. Pre-workout supplements are optional and not required for a good session. The main boost you'll get from them is from caffeine, which you're probably already ticking the box for if you're being honest.
What if I don't feel hungry before training? That's fine for lighter sessions. For harder or longer ones, even a small amount of easily digestible carbohydrate tends to help performance, regardless of hunger levels.
The Bottom Line on What to Eat Before a Workout
What to eat before a workout doesn't need to be complicated: simple carbs, low fat, roughly 60-90 minutes beforehand for harder sessions.
Get this right and your training sessions will consistently feel better, which matters, because how a session feels affects whether you actually want to do the next one.
