So you've got everything you need to workout – gym clothes, gym bag, bottle of water – but are you possibly forgetting something? Have you eaten? You may think it best to not eat before a workout, thinking you're burning or saving more calories, but the truth is that skipping food beforehand will actually hurt you instead of help. Not eating enough before a workout can make you dizzy, lightheaded, nauseated, or lethargic. It can also make you more likely to injure yourself.

Read on to learn more about what exactly you should be eating – and when – pre-workout.
