Weight loss supplements can be found in the health aisles of most grocery and drug stores, but do they really work? According to one recent, diet pills are a waste of money and could be dangerous. They’re marketed as being able to boost metabolism, burn fat and blunt appetite. However, there is “a lack of strong evidence” weight loss pills actually work, say scientists at the University of North Carolina. Perhaps more concerning is that misleading claims “have the potential to harm patients,” they warn. The findings may alarm millions of women hoping to get “beach body ready” for the summer. “Our findings are important for clinicians, researchers and industry alike. They suggest the need for rigorous evaluation of products for weight loss. Only then can we produce data that allows clinicians to provide input and advice with a higher degree of certainty to our patients,” says corresponding author John Batsis, a nutritionist at the university, in a statement.
