I am also thinking about this problem, and I want to use my summer vacation to lose weight. I've been using this method these days: drink 250 ml of oolong tea with rock sugar before and after breakfast and lunch every day (this tea tastes good, don't put too much rock sugar, it's just slightly sweet). This method is persistent and must be adhered to. If the effect is good, you can lose 5 pounds a week! However, you should pay attention to eating less snacks, just eat enough, don't be greedy, eat less greasy meat, eat more light food, and the weather is hot, you can go swimming and play badminton ... so you can definitely fight a battle to lose weight! Let's cheer together!
