Sure, but have a reasonable diet. Breakfast should be rich every day, including soybean milk, pasta, red tofu and fruit juice to supplement vitamins. Eat more coarse grains for lunch. For example, when steaming rice, put half rice and half millet (or brown rice), not just flour and rice. Just drink a little glutinous rice or glutinous rice porridge and eat pickles for dinner. Just eat 80% full for lunch, and remember not to eat too much for dinner. Eat less snacks, such as puffed food, less meat and animal offal (fat intestines, pig liver, etc.). ).

When swimming, you need to swim back and forth in the pool in a standard posture, and the rest time should not exceed 2 minutes. It is recommended to give priority to freestyle. If you are too tired to swim, you can swim slowly with breaststroke. Don't chat with people in the swimming pool. This is a taboo for exercise. Every time you feel tired after swimming, don't delay going to work or have a normal rest the next day. Stick to it for a month, I believe I can lose at least 3 kilograms.
