Normal exercise needs energy to maintain, and we mainly get energy from food. If we run on an empty stomach, the energy to maintain exercise can only be achieved by burning fat. In addition, fasting exercise leads to a significant increase in free fatty acids in human blood. If there are too many free fatty acids, there will be "poisons" that damage the myocardium. This "poison" often leads to abnormal heart rhythm and even sudden death.
Exercise after eating too much will do great harm to the stomach. Drink a glass of milk before exercise, with some eggs, coarse grains and cakes.
