Dieters are shedding pounds with the help of a herb cocktail, says a study. It enables them to lose weight without adjusting their diet. They eat less because, after a meal, they feel fuller for longer. Research shows that those taking Zotrim - a combination of three South American herbs - shed around five pounds in a month. Nutritionist Dr Carrie Ruxton, who conducted the study, says the preparation could provide extra motivation for slimmers plagued by hunger pangs.
