Raspberry Ketone Diet Pills Reviews
Recently dozens of markets have been touting Raspberry Ketone as the all new diet pill many making reference to the Dr. Oz show and its coverage of Raspberry Ketone. However, Raspberry Ketone has not been scientifically shown to be a Fat Burner of any kind.
To begin with we all know that there are no fat-burning miracles. Any responsible medical professional knows that fat-burning miracles just do not exist and such statements can be wrongful. And while, America’s epidemic of obesity finds us willing to try almost anything to lose weight, is Raspberry ketone the answer?
What is Raspberry ketone?
Raspberry ketone has long been used as a chemical additive in perfumes and cosmetics. Its chemical name is 4(-4-Hydroxyphenyl)butan-2-one and also called Frambinone, Oxyphenylon, Rheosmin and Rasketone. It is used as an additive due to its sweet, fruity aroma. It is only found in trace amounts in raspberries (less than 0.1%), which likely makes the natural material from raspberries too costly for use in supplements. As a result, raspberry ketone rarely comes from raspberries and is instead artificially synthesized. Synthetic raspberry ketone is very cheap. It only costs a couple of dollars per pound, which means that despite the high selling price, even a large bottle contains just pennies of raspberry ketone. Clearly then, the real benefits from raspberry ketone are experienced by those who sell it and not those who use it. In any event, it is important to note that regardless of its cost or source (natural or synthetic), I cannot find any research that proves it provides weight-loss benefits in humans.
What is the medical research on raspberry ketone and weight-loss?
We could find virtually no medical research showing fat buring nor weight loss. You can do the research at the National Institutes of Health website (www.pubmed.gov) by typing “raspberry ketone” in the search box. You will find about 35 studies, but only two are remotely relevant to weight-loss. I could not find a single human weight-loss study. Of the two studies I found, one was a mouse study and the other looked at fat cells in a dish. The first study was not blinded (not controlled for bias) and it examined weight-gain in a few male mice fed a high fat diet plus high dose raspberry ketone. It also analyzed some rat liver cells exposed to raspberry ketone. The second study was also not blinded (not controlled for bias) and did not involve humans or any other animal, but instead, just looked at fat cells exposed to raspberry ketone in a petri dish. Neither study specifically showed weight-loss. I also do not recall Dr. Oz mentioning that the level of raspberry ketone given these mice was quite high (0.5% to 2% of food intake). This is equivalent to a human dose of thousands of mgs daily – far higher than the 200 – 400 mgs many Raspberry Ketone diet pills come in. But, the Raspberry Ketone likely used in most diet pills is generally a synthetic chemical additive that to we could not find if it has even been tested for safety at these levels and/or for weight-loss in humans.
Conclusion
Raspberry Ketone diet pills seem like nothing more than the latest fad diet pill that while are well marketed have virtually no scientic studies to show their effectiveness as fat burners. Nor do virtually all of the Raspberry Ketone diet pills contain large enough quantities of the natural Raspberry Ketone to matter when considering the limited mice studies. Perhaps dieters may want to consider other more popular diet pill options on the market with potent ingredients in large enough quantities to make a difference.
