Personally, proper diet and exercise are the most effective. Dieting is not eating nothing or just a little, but eating in moderation. The amount of food eaten every day is a little less than that of the day before yesterday, and gradually reaches the amount that you think can be reduced and maintained, and it has been maintained. Exercise, in fact, an hour's brisk walking every day can achieve the effect of slimming. These are all things that need persistence.
