I suggest you don't use this. It's bad for your health and will have side effects. In fact, losing weight is also very simple. First, you must get up early every day, and you must get up before 7 o'clock. The food in a day should be light, and it is best to give priority to 95% vegetables, such as bean sprouts, cucumbers, bitter melons, peppers, fungus and tomatoes. Don't eat meat if you can. Even if you eat meat, you'd better eat fish and eat three meals a day on time. Try not to eat too much, just 70% full. Never eat snacks even if you are hungry on the way. Don't eat anything after 8 pm, and try to drink less water. Stick to this cycle and live a regular life, and the result will come. Remember to refuse all kinds of temptations, and you must be self-disciplined if you want to lose weight. I wish you get thinner and thinner!
