Do You Need to Eat Before a Workout? A Simple Guide to Fuelling Your Exercise

With the surge in popularity of run clubs, HYROX, CrossFit, Pilates, and so many other forms of movement, a common question we hear is:

“Do I actually need to eat before I exercise?”

and if so, what should I have?

For many people, this question isn’t just practical. It can also bring up uncertainty, mixed messages, or even anxiety around eating.

What does it mean to “fuel” your workout?

When we talk about fuelling your workout, we mean eating or drinking something that provides energy (calories) before you begin.

Things like black coffee, pre-workout supplements, or electrolytes might feel helpful, but they don’t provide meaningful energy. So they don’t count as fuel.

Why fuelling matters

Fuelling your movement can make a real difference, both during your session and afterwards:

  • Improved performance: you can move faster, lift heavier, and go for longer

  • Better recovery: supporting your muscles to repair and rebuild

  • Increased focus and coordination: helping you stay alert and reduce injury risk

  • More stable energy: both during your workout and across the rest of your day

So when should you fuel your workout?

It’s common to wonder if you really need to eat before movement, especially when there’s so much messaging around fasted training or “not needing” food.

The reality is, you don’t need to meet strict criteria to fuel your body.
 But there are some situations where fuelling beforehand can be especially helpful:

  • If your session will last longer than 60 minutes

  • If you’re training at a higher intensity

  • If it’s been more than 2–3 hours since you last ate

  • If you’re noticing low energy, fatigue, or difficulty concentrating

  • If you have rules about needing to exercise on an empty stomach

If any of these apply, your body will likely benefit from having some fuel beforehand.

But just as importantly - even if none of these apply, you can still benefit from fuelling.

Hunger isn’t always a reliable cue, particularly with early morning training, busy routines, or when you’re navigating an eating disorder. You don’t have to feel hungry to justify eating.

If fuelling before movement feels uncomfortable or goes against your usual rules, this can be a gentle place to start challenging them. Fuelling isn’t about doing things perfectly. It’s about supporting your body so it has access to the energy it needs.

Closing

Fuelling your body before movement isn’t about getting it “right” or following perfect guidelines. It’s about offering your body support, even when it feels unfamiliar or uncomfortable.

If this is something you’re working on, you don’t have to figure it out alone.
