When people exercise for a long time, the heat provided by sugar in the body is far from meeting the needs, so the fat in the body is oxidized and decomposed to generate heat energy for human use.

Anaerobic exercise;

When people do strenuous exercise for a short time, the human body is in a state of temporary hypoxia, and a large amount of sugar in the body is broken down into muscles to generate energy. So anaerobic exercise does not consume fat.

The mechanism of exercise to lose weight is:

The main energy of human exercise comes from sugar and fat.

During aerobic exercise, the utilization of free fatty acids and glucose in blood is increased by muscles, which leads to the release of a large number of free fatty acids from adipocytes and makes them thinner. At the same time, excess blood sugar is consumed and cannot be converted into fat.

Precautions for reducing fat:

1, diet needs moderate control. In the week-long citrus weight-loss plan, you can drink green tea besides boiled water, but you can't touch all drinks containing sugar or carbonated water. In addition, try not to add salt, spices and sugar to your meals.

2. The implementation time should not be too long. In the week when citrus loses weight, the diet needs to be moderate, which is a bit like semi-fasting to lose weight. The same can't be carried out all the time. The cycle is one week, and the first six days are carried out according to the above menu, and then 1 day is resumed.

3. eat with white tendons. Pectin in citrus can inhibit the absorption of sugar. Pectin is stored in white gluten, and vitamin P in white gluten helps you strengthen blood vessels and improve immunity. Don't worry about resistance decline during weight loss.

4, you can't eat too much to lose weight. Citrus, which is beneficial to weight loss, beauty and health, feels sweeter and more watery in winter, because the concentration of sugar is higher in this rich season, so it is delicious.
