The demand for a weight loss trim-fast is high, so the supply is high. We live with a free-enterprise economy in this society. People wish to be thin. People want products to help them in this endeavor. Therefore, manufacturers find and produce a weight loss diet pill. Whereas pharmaceutical companies are regulated, the weight loss diet supplement industry is not.
And isn't that the real problem? How would a person feel if they purchased Amoxicillin for their child at the local pharmacy and found out that it was nothing more than sugar water? This doesn't happen with pharmaceuticals or the prescription weight loss pill because these are regulated by the Food and Drug Administration.
In the end, though, a person duped by a fake weight loss trim fast pills, whether it's Hoodia or something else, do not suffer anything more than a bit of disappointment and loss of money. The damage done by a patient receiving a placebo when they needed a life-saving drug is far worse.
