If you want to stay in shape or lose weight, you can't rush for success. Usually eat fruit if you want, and eat some fruit and drink some water or hot soup half an hour before dinner. The initial loss of appetite will make you feel less sad. For example, if you usually eat two bowls of rice, eat one and a half bowls first, then eat more vegetables, and then reduce the amount every once in a while. It's a good idea to eat less and more vegetables when eating. A friend of mine lost a lot of weight in this way before she got married, but she is so cruel that I can't stand eating only vegetables at every meal. After all, she is motivated. For once in her life, she is the center of the world, and it is worth suffering. Losing weight is mainly suitable for you, and the most important thing is to pay attention to your health.
Try yoga. I used to practice yoga for 3-4 hours after dinner to lose weight. It's not difficult, but I always sweat after I finish. Of course, you should have an early dinner and eat less. The most important thing is persistence.
