Swimming is a sport that consumes a lot of energy. After swimming, you can eat some coarse grains, fruits and vegetables, bacteria and algae containing dietary fiber.

The reason for this is the following：

If you want to lose weight and keep fit by swimming, you must pay attention to the intake of dietary fiber. Dietary fiber itself has no calories and cannot be digested and absorbed by human body, but it can reduce the absorption of fat in food. Although dietary fiber can expand 80 ~ 100 times after absorbing water, it is helpful to enhance satiety and reduce calorie intake. Dietary fiber mainly exists in coarse grains, fruits and vegetables and bacteria and algae. Red beans, peas, sweet potatoes, celery, spinach, Chinese cabbage, apples and bananas are all foods rich in dietary fiber.
