Before a workout, the human body may need an energy source so that the body does not feel drained while exercising. You do not want to eat a 3-course meal, but you also want to make sure you have something at least. Here are some guidelines to keep in mind when deciding whether or not to consume a snack.
Keep it Simple
Your pre-workout snack should not be very complex. Simple carbohydrates are what you should be aiming for when deciding what to eat, as they break down into glucose for instant energy for your muscles to use. Good examples of this would be a piece of toast or a piece of dried fruit. Protein is not bad for your nutrition before a workout either. These help repair your muscles as you attempt to become stronger. A good example of this would be a few cashews or a peanut butter sandwich.
Give Time for Digestion
You want to keep in mind when you are eating a snack as well before entering a workout. The general rule-of-thumb for eating a workout is thirty to sixty minutes before. This should give your body just enough time to digest some nutrients. As everyone’s body is different though, you have to experiment to see what your body can handle before trying something too big nutrition-wise.
If you have not been eating snacks before a workout before, you want to make sure that you are not overwhelming your body with a routine that it is not used to. Start with a few crackers before a workout, and build up to what you can handle over time as to not cause you discomfort. Eventually, your body will become accustomed to being supplemented with energy and will be able to absorb nutrients easier.
