In order to maximize the efforts and results of your workout, it is important that you fuel your body with the right nutrients beforehand to keep you going. In addition to drinking water before a workout to keep you hydrated, you should also have an adequate meal to keep energy levels high.
What should you eat?
A pre-exercise meal should ideally consist mostly of slow-burning complex carbs, such as those found in vegetables, fruits, and whole-grain bread. The reason you should choose foods that are high in complex carbs is because these carbs take longer to convert to glucose than simple carbs. Eating complex carbs rather than simple carbs before a workout will keep your blood sugar levels consistent and prevent you from having an energy crash in the middle of your workout.
How much should you eat?
When it comes knowing how much you should eat, be sure to follow this one simple rule: the less time there is before your workout, the less you should eat. Bigger meals take longer to digest, so if you are going to work out in 4 hours or more, go right ahead and eat that big breakfast. But, if you are working out in just an hour or so, it is best to keep your pre-workout meal to a snack that is 300 calories or less so that it can be digested within the hour.
The most important thing is to listen to your body and do what is right for you! Maybe your body will be more energized if you have a light snack before the workout, and maybe your body will work better with a big meal that you consumed a few hours beforehand. Either way, providing your body with the right foods to fuel your activity will help you to get the most out of your workout!
