It doesn't work very well. I saw it used on a cat, but now I have stopped using it. I switched to another product, and now I have lost 8 kg a month. Pay attention to the diet structure, what to eat and what not to eat is very important! I read about how to lose weight in Zhou Xinlei's diet diary. I can read it. For example, I paid attention to my diet yesterday. Breakfast: a corn/a vegetable bag/a glass of low-fat milk! Lunch: a bowl of rice, two vegetarian dishes and a meat dish! Vegetarian dishes suggest leafy vegetables, and meat dishes suggest fish and shrimp first, followed by chickens and ducks, followed by cattle and sheep. It's best not to use heavy spices in cooking, such as grilled fish, barbecue and stir-fry. I usually eat a coarse grain and a vegetable for dinner! Or two servings, for example, I had dinner yesterday: a purple potato/bean sprouts and oily wheat dishes!
