The only research on the effect of raspberry ketones on fat are a handful of animal studies. The studies were done over the last 1. Researchers looked at the effect of raspberry ketones on rats, mice and rabbits. One 2. 00. 5 Japanese study looked into the effects of raspberry ketones on obese male mice fed a high fat diet. They wanted to see if these compounds could prevent obesity and reduce overall body fat and visceral fat stored around organs. One of the results of this study concluded that the addition of raspberry ketone helped: Reduce body weight by speeding up processing of fat. Reduce fatty tissue, especially liver fat stores. However, this was a small study of six mice and the same effects have not been tested or observed in humans. A Korean study carried out in 2. Researchers concluded that by stimulating lipolysis (the breakdown of fats) and other chemical processes, raspberry ketones suppress fat accumulation and improve fat metabolism. In this case, the effects of raspberry ketones were documented but the underlying mechanism of how this worked was not confirmed. Also, the research conducted only involved isolated cells in test tubes. There is no way to know whether the same results would be produced in people. The unknown potential for harm. Raspberry ketones in food and cosmetics are generally considered safe but no one knows what short or long- term effect raspberry ketone supplements could have on your overall health. That's because there has been no study to document potential side effects. There are also no studies that look at potential drug or food interactions.
