Apple claims to be the healthiest fruit in the world. As the saying goes, "An apple a day keeps the doctor away." During fitness, apples can help the human body provide polyphenols and increase muscle strength. Moreover, the calcium content of apples is much richer than that of ordinary fruits, which helps to metabolize excess salt in the body. "Malic acid" can also metabolize calories and prevent thigh obesity.

Step 2: bananas

Bananas contain a lot of potassium. By eating bananas to supplement potassium, you can balance the acid and alkali in the body, so as to better digest the fat in the body. In addition, bananas can supplement the electrolytes consumed by the human body due to exercise, especially those who are prone to cramps during exercise, and can eat more bananas. Bananas are also low in calories. A banana with a net weight of about100g has only 87 calories, which is only about half as much as the amount of white rice in a meal (150g, 220 calories).

3. orange

Oranges are rich in vitamin C, which can help the human body to promote the synthesis of nitrous oxide, and because of its rich juice, eating them during exercise can effectively replenish the water lost by the body. It is recommended to eat oranges during low-intensity exercise, especially for women, which can make the skin more elastic.

4.grapefruit

Grapefruit is not only extremely low in calories, but also rich in special enzymes, which can affect the body's absorption of sugar and make it difficult to convert into fat. Many people find it particularly difficult to lose fat on the back and shoulders. In fact, the increase in back fat is mostly due to the absorption of excess sugar in the body, which is then converted into fat. Therefore, in order to eradicate back fat, grapefruit is the most suitable choice.

Thirty years ago, the diet using grapefruit was highly praised by women in western countries. A recent study in the United States found that adding grapefruit and grapefruit juice to the diet menu can effectively lose weight.

5.pineapple

Pineapple is rich in fruit acid, which can help the body recover and relieve muscle fatigue caused by fitness. Plus pineapple contains bromelain, which can eliminate inflammation or edema caused by exercise. In addition, the proteolytic enzyme of pineapple is quite powerful, which can help protein digestion of meat, but if eaten before meals, it is easy to cause stomach wall damage. Therefore, we must pay attention to the time problem when eating pineapple.
