Doing a good job in several aspects can reduce a lot in a summer vacation. First, eat high-quality protein and fruits and vegetables (not fruit and vegetable juice) with high dietary fiber and low calorie, and then develop exercise habits. Any exercise that is a little tired but can be exercised for more than half an hour at a time, such as jogging, walking, skipping rope and strength training, can be done every day. At first, it must be difficult for me to know the happiness of sports after I get used to it for a few days, because sports will make my brain produce more dopamine, which will make me feel happy and even have the pleasure of sports addiction. Later, if you don't exercise for a day, it will be very uncomfortable, thus forming a virtuous circle. However, exercise once or twice a day can be more effective, but you should also do what you can and not be too tired. In addition, exercise should pay attention to safety, warm up well, and learn correct movements and postures. Don't get hurt. Finally, getting enough regular sleep every day has a great influence on losing weight. Many people lose weight because they don't pay attention to sleep and often stay up late.
