Walking after meals can effectively affect the gastrointestinal digestive system, and strenuous exercise also has the risk of appendicitis. But walking without eating to lose weight is said to burn fat, but it is easy to cause hypoglycemia. A good way is to drink a cup of warm light honey water in the morning, or eat a little, then take a walk to lose weight, and then come back for breakfast. Honey water can provide you with a small amount of sugar to convert into energy, reduce the risk of hypoglycemia, and do not hinder normal exercise consumption. Drinking warm water in the morning can also play a role in replenishing water and detoxifying.
