Recently, a popular physician and host of a well-known talk show touted raspberry ketone as a "miracle fat burner." Since then, suppliers of the product have had a difficult time keeping raspberry ketone supplements on the shelves. Most of us are aware of how trying the weight loss process is, which is why new information about products which can help in the journey is always received with excitement. Unlike fad diets or diet pills, however, raspberry ketone is a natural substance and can be used by most anyone.

Though many diet pills may already contain raspberry ketone extract, they also contain a host of other substances, some of which may be harmful. Pure raspberry ketone supplements contain only an extract from the raspberry plant. Raspberry ketones occur naturally in the berry, and have been used for some time to add aroma to cosmetics and certain foods (such as sodas). Only recently have raspberry ketone supplements started to draw attention, but the FDA has already declared this extract safe. In fact, raspberries have been known for some time to be beneficial for the body because of their high levels of antioxidants. The only potential for harm would occur if you have an allergy to raspberries.

Though naturally occurring in raspberries, this ketone occurs at very small levels. To obtain the level of raspberries found in a 100 mg pure raspberry ketone supplement would mean eating nearly one hundred pounds of berries. Of course, the amount of sugar and calories consumed would obviously cancel out any weight loss benefit of the ketones. For those seeking the weight loss benefits of raspberry ketones, a pure supplement is the best option.

So how does it work? Raspberry ketones are similar in structure to capsaicin, which has been known for years to increase fat metabolism. Raspberry ketones do this by stimulating the secretion of the hormone adiponectin. Adiponectin is normally found in fatty tissue and increases the body's insulin sensitivity and fat metabolism. Both of these actions help reduce fat cell mass and activate weight loss. When used in conjunction with a healthy diet and exercise, pure raspberry ketone supplements will only supercharge weight loss.

There is scientific evidence to back up the claims of pure raspberry ketones as a "miracle fat burner." A 2005 study found subjects on a high-fat diet which also consumed raspberry ketone supplements were prevented from gaining weight, increasing fat around the liver, and higher triglyceride levels, all of which are negative effects of a high-fat diet. A similar 2010 study also showed increased levels of adiponectin in subjects consuming pure raspberry ketones, which may have also played a part in the reduced fat storage and increased metabolism of fatty acids seen in the study.

Though exhaustive clinical studies have yet to be done, the results seen by those already taking pure raspberry ketone supplements speak for themselves. To buy garcinia cambogia (or Raspberry Ketones) simply take a look around online. There are now dozens of competent manufacturers offering this product. The ideal dosage, according to "The Doctor Oz Show" is 800 milligrams.
