A question that is often asked: why do some people (few) lose weight even if the weight-loss product is a scam?
For example, if we claim that Herbex products have no evidence to back up their claim to be effective in weight-loss, and indeed, as we argue, there is no proof the ingredients contribute to weight-loss and particularly at the dose being used.
