Generally, it is not recommended to work out on an empty stomach. Working out on an empty stomach can cause your body to break down muscle tissue for energy instead of relying on stored carbohydrates and fat, which can lead to fatigue and a decrease in performance during your workout. Additionally, exercising without eating can cause you to feel dizzy or lightheaded due to low blood sugar levels. For optimal performance and energy, it is best to eat a small snack or meal containing complex carbohydrates, protein, and healthy fats before exercising.

What happens if you exercise on an empty stomach?

Exercising on an empty stomach may lead to a decrease in performance and an increase in fatigue. When you exercise on an empty stomach, your body is forced to rely on its glycogen stores and muscle protein for energy, which can lead to an increased rate of muscle breakdown and an overall decrease in performance. Additionally, exercising on an empty stomach can also lead to a decrease in blood sugar levels, which can cause feelings of lightheadedness and fatigue. As such, it is generally recommended to have a light snack or meal before exercising, in order to ensure that your body has enough energy to perform at its peak.

Is it better to exercise before or after breakfast?

It is generally recommended to exercise before breakfast, as this can help to boost metabolism and burn more calories. Exercising after breakfast can also be beneficial, but may cause a spike in blood sugar levels, which can be uncomfortable for some people. It is important to listen to your body and experiment to figure out which time of day is best for you.
