Rasberry Ketones may be the newest blockbuster fat loss supplement. Or, maybe not…
I always try to keep up with the latest research on fat loss, and am just as curious as the next trainer about what supplements can assist with reducing body fat. I am especially interested in nutritional supplements that not only help with improving body composition but also have other anti-oxidant or life-extension properties.
The truth is that most of the “new” blockbuster fat loss (or muscle building) supplements aren’t new at all. Most of the time they’re just obscure products that have been around for a long time that somehow fall back into the limelight. They get “recycled” because people randomly decide to try them again, or new research comes out supporting their efficacy. Other times things are a little more suspect. Believe it or not, the supplement companies have some serious pull and can spend money to get their products out their in our faces – and pretty damn fast at that.
In this case the new kid on the block is Rasberry Ketones…
This strange “new” supplement caught my eye after I read an article about how it was promoted by Dr. Oz on his TV program The Dr. Oz Show…
Now, just to make it clear, I didn’t see it on his show because I don’t watch his show. Not because I don’t think he’s a good guy, but because half (yes, literally about 50%) of the info he shells out on the program is recycled, unoriginal crap. For instance, the guy pushes whole grain bread like it’s actually a great diet staple that should be consumed in large quantities for weight loss. He also seems to promote unoriginal “safe” experts on his show. Keep in mind that Dr. Oz got his start on TV through Oprah – the woman who used to make people instantly rich and famous by merely mentioning their books, products, etc. on her show. So, sure, maybe he has a vested interest in keeping things pretty “vanilla”.
But what’s interesting is that this isn’t the first time he’s recommended one of these more unusual dietary aids. He typically touts them as a that “one miracle weight loss pill that you have to start consuming” (or something to that effect) and he probably gets a lot of viewers that way. To his credit (or not?) at the end of all of his shows – even after he’s pushed one of these awesomely powerful nutritional products – he emphasizes that you have to diet and exercise to lose weight. And while I would say the same thing, it makes you wonder, what’s the story? Do the pills work?
While I won’t go into some of the other products he’s recommended, I will drop some knowledge about Rasberry Ketones. Here’s the lowdown.
First of all, Rasberry Ketones aren’t new at all. They’ve been around for a while. They’re just one of those “out there” pills that you wouldn’t have otherwise seen unless you went exploring in the back of a health store. But lately they’ve received a little more attention. Here’s the deal: Rasberry Ketones are compounds found in red raspberries and are on the USDA’s list of ingredients that are generally recognized as safe. They give rasberries their aroma, but are typically present in very low amounts.
As stated on The Dr. Oz Show, it would take 90 pounds of fresh berries to get the same amount of ketone that’s found in the pill form. What the show failed to mention is that due to this natural scarcity, the raspberry ketone found in supplements is usually synthesized industrially.
Raspberry ketones “turn up” the metabolism through two mechanisms: increasing the levels of norepinerphrine and adiponectin. Increasing the norepinephrine levels causes the body’s temperature to rise, which in turns makes the body turn up lipolysis (fat burning). Additionally, Raspberry ketones also increase levels of adiponectin, which is a hormone that helps the body decrease glucose levels. When you keep glucose levels down, you decrease the chance that the body will store any unused glucose as fat. That’s why lower levels of Adiponectin are found in people with insulin resistance and diabetes – than in others.
So, to put it simply, Rasberry Ketone is a stimulant, just like many of the other weight loss supplements out there. And, because of this, it can affect things like blood pressure, heart rate, and even thyroid function. Other side effects probably include insomnia and agitation.
But the ultimate question is still the most important one: are Rasberry Ketones effective for fat loss? The truth is that the research is scant: two small studies on mice show that the supplement makes them less likely to gain weight, but there are no placebo-controlled studies on humans.
Remember, it takes 90lbs of berries to synthesize the ketones that you put into your body with one pill. All things considered, it might be safer to just polish off a bowl of Rasberries every so often…
