Why Has Science Just Now Realized Raspberry Ketones Role In Fat Burning and Weight Loss?
It’s all about the smell. Researchers had previously tested other aroma compounds like capsacin in red peppers and synephrine in citrus peel on rats consuming a fatty diet. They discovered that each led to significant lipolytic activity, and concluded that these compounds had the ability to break down fat.
This opened the door for the study of raspberry ketone as well, since it was another compound noted for its odor and shares a similar chemical structure to capsacin and synephrine. Research was soon underway to determine if raspberry ketone had the same anti-obesity potential and the ability to alter lipid metabolism as the other compounds.
Lab Studies Confirm Anti-Obesity And Weight Loss Benefits Of Raspberry Ketone
The most notable studies on raspberry ketone have been performed on mice to test the effect of raspberry ketone on obesity. Skeptics of the weight loss benefits of raspberry ketone will often point out that human clinical trials are lacking. And, yes, more human clinical studies would be ideal. That said raspberry ketones have been deemed generally safe for human consumption by the FDA since 1965, and humans share very similar genetic makeups to mice, which is why mice are used so often in biomedical research.
For a ten-week period, mice were fed a fatty diet, while simultaneously being given raspberry ketone each day. Researchers observing the mice saw fewer instances of fatty livers and a decrease in visceral adipose, or abdominal fat if you don’t speak geek, despite the consumption of a high-fat diet. An increase in norepinephrine-induced lipolysis, the break down and decomposition of fat, was also observed in several rat fat cells.
In another experiment, mice were fed only a high-fat diet for six weeks. Needless to say, it was observed that the mice gained considerable weight. For the next five weeks, they continued with the same diet, but were also given raspberry ketones.
Despite consuming the same high-fat diet, researchers observed that the raspberry ketone prevented any further weight gain. Not only was this amazing, but many of mice that had gained weight during those first six weeks with no raspberry ketone, had actually lost some weight once raspberry ketones were added to the mix. This is again with THE SAME EXACT FATTY DIET! This is why Dr. Oz is so enthusiastic about the potential of raspberry ketones as a potent fat burner.
In Vitro Fat Cell Study Confirms Raspberry Ketone Can Boost Adiponectin
Adiponectin is a protein that the body utilizes to regulate its metabolism. Higher levels of this hormone help boost the body’s metabolism. Fat is broken up more effectively and we are able to more efficiently burn fat. Stored body fat is commonly associated with lower levels of apiponectin.
Researchers examined how raspberry ketones affected in vitro fat cells. They found an increase in fatty acid oxidation and suppressed lipid accumulation in 3T3-L1 adipocytes – a higher secretion of adiponectin than controls indicated and an enhanced ability to break down body fat.
The Rag-Tag Research Geeks Conclude…
While we would like to see more clinical trials performed to confirm results on humans, not mice, we share Dr. Oz’s enthusiasm over the discoveries made in laboratory testing. We are also encouraged by testimonials we’ve received from real people. We thereby believe that a high quality, pure, all-natural raspberry ketone supplement can help burn fat when combined with a sensible diet and exercise. We don’t necessarily subscribe to a lot of the hype of people losing 30 to 40 pounds in a week or two, but raspberry ketone seems to be effective in shedding unwanted body fat in a short amount of time, in modest 7-10 pound increments, and an aid in keeping weight off.
