The effect of losing weight in summer should be the most significant. I think it's best to control diet if you want to lose weight. It's not that you don't eat anything, but eat less and don't consume too many calories. Losing weight is a slow process. You need the right method+perseverance+hard work+confidence. You should eat less, don't eat too much ice cream, don't eat too much meat, do more exercise, such as playing ball games, running, skipping rope ~ ~ ~ ~ eat more fruits and drink more water, go out for a walk after meals, and go.
