Losing weight is the standard for most dieters to measure the success of losing weight, but in fact, fat accumulation is the real reason. Scale masks the fact that everything happens in bait and switch. Diet pills containing "diuretics" will transfer 70% of the water in the body and lose weight quickly. The same principle applies to diet pills containing rhubarb, senna and other antidiarrheal effects. However, these two drugs can only take effect quickly. Once you stop using it, drink water and eat, your weight will rebound.
