It may be the first drug to eliminate or regulate almost all the complex processes of weight gain and weight loss, without involving any side effects. Weight loss pills work by making the brain think that the body does not need food, and thus the appetite is suppressed. This suppresses the appetite in turn so that the person cannot eat much and consequently will only eat a very small amount.
In certain countries, such as the US, dietary supplements have been extensively marketed and are available without a prescription, but they must be carefully scrutinized before taking them.
