First off, yes you should eat before you workout! The thought that you shouldn’t eat before you workout in order to burn more fat is a myth. Working out takes up a lot of energy, meaning you have to eat in order to have that energy to expend. Depending on your type of workout, you should eat between 30 minutes to 2 hours prior to your workout. But what does that meal or snack look like?
Low glycemic index (GI) carbohydrates and some protein. Carbs break down into glucose in your body, which is the main energy source that your body will use during working out. The glycemic index measures what affect carbs will have on your blood glucose level. Low GI carbs are released slower into your system and therefore are better for sustained energy in the body. All that to say fruit is your friend before a workout. Bananas are especially great because they are also packed with potassium to prevent muscle cramps.
The phrase carbo loading is also something that you might have heard. This is the idea that if you load up on carbs prior to a workout, usually a run or swim or endurance exercise, that the carbs with hold you over and release the energy you need when you need it. This is a proven theory, but with an important asterisk. Carbo loading shouldn’t be a pre workout meal, it should be a night before a big race with plenty of time to digest meal.
