Serious diet pills are intended for people who are overweight to the point of being considered obese . Therefore , they are known as anti - obesity drugs ; and should not be used for quick , temporary weight loss . Diet medications and supplements will not simply " melt " away all your unwanted fat and permanently solve any weight problem you might have .
