It is not suitable to exercise on an empty stomach

Many people exercise on an empty stomach. Doing exercise on an empty stomach is like driving a tank without oil. Your body needs energy to keep running. Healthy snacks, such as oatmeal or bananas, can be easily digested and provide you with the extra energy you need for your next workout. You should especially not go on an empty stomach when exercising in the morning, because after a night, your stomach is already empty and the calories have been consumed, so you need to add some "fuel" to your body.
