RaspberriesIf you read magazines or surf at the Internet, you’re going to be bombarded by ads and other promotional listings for the raspberry diet, the new “miracle fat-burner in a bottle” ingredient that is promoted to melt away flab while you change absolutely nothing else in your life. There’s just one tiny problem: Raspberry ketone shows absolutely no efficacy for weight loss, and there isn’t even one tiny study demonstrating that anybody ever lost weight taking the the raspberry diet.


A natural antioxidant compound found in cranberries and other plants, raspberry ketone has become the rage for dieters despite vapor-thin science conducted in test tubes using mice. Also known as rheosmin, the raspberry diet has been used as a flavoring agent for almost 100 years. In the cosmetic sector it is an expensive smelling agent.

In the Japanese rat study, rats given a high fat diet and raspberry ketone extract did not become obese. The study results were reported in February 2005 in the journal Life Sciences. The Korean mouse study was reported in the journal Planta Medica in April 2010. In male rats, administration of high doses of the raspberry diet prevented an increase in body weight when the rats were fed a high fat diet.


To start, rats are not people. While  rats are often used as precursors to human studies, we only share approximately 85 percent of the same DNA as rats, but we also do not share 15 percent. The rats in the two studies lived in cages, not in the real world. And the rodents were fed controlled diets. They had no access to fat-producing snacks. They could not get up in the middle of the night to raid the refrigerator. In other words, there is no valid connection of any sort between these two rodent studies and your likelihood of losing weight.


According to proponents, the raspberry diet supposedly helps to enhance activity of the human hormone adiponectin, which plays a role in regulating blood glucose and body weight. Adiponectin works in the body to modify blood glucose and insulin. So it sounds as though raspberry ketone extract would be a weight loss aid, right? However, to date there is not even one human study proving any weight loss at all as a result of consuming raspberry ketone extract. Marketers of the raspberry diet rely on the rapid repetition of pseudo-science to produce the impression that using this pill for weight loss is valid. Since many people do not understand that much about human biochemistry, the pseudo-science that is spouted for this supplement can sound impressive, but proceed with caution. People may buy a couple of bottles of raspberry ketone extract, take the product, fail to lose weight, and move on to the next illegitimate diet craze.


As obesity rates soar in the U.S. and more people become desperate for help to lose weight, we will continue to see an endless number of diet crazes, most based on agents that do not actually perform so marginally that no significant weight reduction can be achieved. The science of weight loss is very well established. Reduce calories, eat cleaner types of foods, exercise regularly to burn calories, and you can ultimately lose weight steadily. Fail to engage in these fundamentals, and nothing happens. The the raspberry diet craze may help you lose weight, but there isn't enough studies conducted.
