A new dietary supplement containing an extract from red raspberries is currently the hottest diet product in the U.S. — but not without controversy.
Critics say the compound — called raspberry ketone — causes such a significant amount of weight loss that it runs the risk of being abused by non-dieters. Proponents argue that research shows the nutrient to be both safe and effective and that banning the natural compound would be akin to banning vitamins.
One thing people on both sides can agree on is the controversial new supplement works.
Several recent studies from Japan show that raspberry ketones — which are chemically similar tocapsaicin, the heat compound from chile peppers — significantly increases fat oxidation (burning), especially the fat that builds up in the liver.
In 2010, Korean researchers reported that raspberry ketone increased fat cells’ secretion of a hormone called adiponectin that regulates the processing of sugars and fats in the blood. The reported benefits are impressive: Increased total weight loss, including a significant reduction of abdominal fat — with zero side effects.
In fact, not only were there not any side effects, but a 2012 study from China found that raspberry ketones had several health benefits — including improved cholesterol levels, insulin sensitivity, and reduced fat in the liver.
And if all that weren’t reason enough to have desperate slimmers stocking up, one of America’s leading medical doctors is a fan, recently calling raspberry ketones a “miracle weight loss supplement” on his Emmy-winning daytime TV show.Click here to watch the episode.
