The choice of exercise time is not empty stomach or after meals. But your blood sugar, that is, whether you are hungry or ready to feel hungry, the choice between eating and not eating.
& lt2 & gt
An empty stomach means that your blood sugar begins to drop and your energy begins to be insufficient. For example, after lunch, I will go to exercise at 5 or 6 o'clock after work. That kind of high-intensity exercise makes your blood sugar run out at once, and your liver sugar consumption is not enough, forcing your body to enter a state of compensation.
If exercise is mainly anaerobic exercise, it will definitely decompose the body protein. If it is mainly aerobic exercise, it mainly decomposes fat, and at the same time it will destroy the protein of the body.
When the body provides energy without glycolysis, it will produce a large number of intermediate products, such as lactic acid, pyruvate, purine, pyrimidine, uric acid and so on.
Therefore, it is not recommended to exercise on an empty stomach and hypoglycemia. Good time is 3: 00, 4: 00, 5: 00, and have dinner together after exercise and fitness.

Exercise after meals is not good either. It is not recommended. Just after eating, the whole body blood flows to the stomach to help digest food and absorb nutrients.
At this time, if you go to exercise and fitness, the blood will be forced to be diverted and concentrated in the limbs, hands and feet, and the blood flowing to the stomach will be reduced, which will seriously affect digestion. Can cause indigestion, food nutrition malabsorption, leading to gastrointestinal diseases.
It's best to rest for an hour after dinner before going to exercise.
Exercise and fitness are conditional. The so-called fitness exercise, in physical and physiological performance, is the expenditure of energy and nutrients. If energy and nutrition can't keep up, the consumption of the body will become loss.
Lack of protein's fitness exercise will consume human muscle tissue. Without calcium and magnesium, the body is prone to osteoporosis and the muscles are hard. Without vitamin B exercise, the body will produce a lot of acidic substances, and the body's metabolism will slow down. Without vitamin C exercise, human ligaments and muscles are easily brittle.
