There is a new rumor that has raspberry ketones in the spotlight as a weight loss supplement.

Affirming that raspberry ketone supplements can burn fat and prevent weight gain, even despite a high fat diet. But can they really do that?

Raspberry Ketones - Raspberry Ketone - are chemical compounds that give raspberries their tempting aroma. When ketones are extracted from raspberries, that can be used to give fragrance, taste or color to things like soft drinks, ice cream and cosmetics. Now with dietary boom, we want to know if these benefits are really effective.
Properties attributed to

Raspberry Ketones have thermogenic effects that occur in the body with important fat burning because the heat makes the body causing it to raise the temperature basal metabolism is altered, requiring more energy, shows that reserves fat, making kilos was lost, according to Lisa Lynn said, personal trainer and fitness expert on “The Dr. Oz Show.”

Stimulate the production of adiponectin, a hormone present in fat tissue and acts on the way for the body to metabolize fats. ” They make you fat within cells break more effectively, helping the body to burn more quickly… to get the same benefit from the fruit, you would have to consume 40 kilos of raspberries,” he says on the website U.S. program.
The science says

So far the scientific collection of its effects on weight loss data from the last 10 to 15 years and have been tested only in animals - rats, mice and rabbits.

In 2005, a Japanese study looked at the effects of raspberry ketones in obese male mice fed a high-fat diet. They wanted to see if these compounds could prevent obesity and reduce total body fat and visceral fat that is stored around the organs. The result of the study concluded that the addition of raspberry ketone helped :

• Reduce body weight by accelerating the processing of fat

• Reduce fat, especially the fat reserves of the liver

In 2010, a Korean study took a closer look at how raspberry ketones can work to prevent obesity. The researchers concluded that by stimulation of lipolysis ( fat breakdown ) and other chemical processes, raspberry ketones suppress fat accumulation and improve fat metabolism. In this case, the effects of raspberry ketones but the underlying mechanism of how this worked documented not confirmed.

Also, research conducted involved only isolated cells in test tubes.

Until further clinical studies showing such results in humans, experts say it’s best to wait. Instead of that, focus on a healthy, balanced diet and regular exercise. Raspberry Ketones in foods and cosmetics are generally considered safe.
