Brindeberry comes from the rind of an exotic citris fruit (Malabar Tamarind) and has the active ingredient Hydroxycitric Acid (HCA). Products include 'Slim Life', 'Brindeslim', 'Medislim' and 'Beer Belly Busters'. It's commonly claimed that brindleberry reduces the conversion of carbohydrate into fat (de novo lipogenesis) and reduces appetite.
But the conversion of carbohydrate into fat is not the basis of most fat storage in humans and to say that it works on appetite is an oversimplification. Six peer-reviewed studies have examined HCA and weight loss in humans. Of these, five reported some positive results, but all had problems with their experiments. A recent randomised-control study found no differences in weight loss between 1500mg of HCA a day and another given an HCA-free placebo over a 12-week period.
Thumbs down! The theory of how brindleberry could work is questionable and there isn't any strong support for it in weight loss.
