1. Never trust those slimming products, because they are harmful to your health. Even if you can lose weight with those things, it is unhealthy. If you stop using it or use it for a long time, it will definitely rebound.
2. Losing weight can only be achieved through a reasonable diet, a combination of aerobic and anaerobic exercise, and a good life schedule. It will only be effective if it lasts for more than half a year, and it is not easy to rebound.
