We have all heard you shouldn’t eat right before a swim. Now there’s a new study that suggests you may not want to eat before exercising to get the most out of your workout.
The new trend is called fasted cardio and encourages working out first thing in the morning before breakfast. According to studies, the body will burn more fat. The body typically draws on carbs for energy. Without food, your body will only have existing fat to use for energy. Then, after your fasted workout, studies say that your body will be better able to absorb carbs and proteins. The idea is that your body will use the food to restore energy instead of storing it as fat.
The overnight fast should be 10 hours or more. Aerobic exercise that is low- or moderate-intensity is also recommended. Researchers caution using fasted cardio if the person feels weak and the feeling discourages the person from continuing with the workout. So fasted cardio may not be for everyone.
