If you lose weight, it is not recommended to believe and take any diet pills. Some people will have side effects instead of losing weight. Whether you are fat or not is related to your own physique. Some people eat a little fat, while others eat a lot but are not fat, which is determined by nature. Then we can lose weight and strengthen our resistance through exercise, which is the healthiest and most effective way. Obesity is considered to be the result of environmental factors that lead to obesity, and it is also the adaptive response of human beings to intermittent satiety and hunger in the process of evolution. Drugs are used to increase energy consumption and suppress appetite. The function of diet pills can not be simply considered as "losing weight", but "keeping weight in a state of losing weight for a long time"
