The first is to avoid overeating. We must eat a lot during the Spring Festival holiday, such as fish, fried food, hot pot beer and drinks. If we don't hold back, that year's efforts will be in vain, so you should subconsciously tell yourself to eat less or even not, try to restrain yourself, think about your own hard work and think about the beauty of losing weight.
Besides, I can divert my attention, chat with others or do something else. Don't just stare at food all day. When your attention is not on food, you can reduce your food intake.
If your self-control is really poor, I think you can tell your relatives and friends to give supervision and ask them to help supervise you. Once you eat too much or can't help it, come out and stop you.
Exercise is also very important at this time. Don't be lazy. Think about the beautiful appearance, and you must control it.
