Dr Oz. on Raspberry Ketones

Trust me…I’m a Doctor!

We all know even the blind squirrel gets a nut every once in a while, and Dr. Oz supports this grandparent-wisdom by actually making the theoretically sound suggestion of using Raspberry Ketones for fat loss, albeit buried amidst a pile of nutritional quackery per usual.

Instead of me handing the good doctor his own ass, I want to make this interesting. I’d like to hear the readers of this blog chime in and respond to the statements made by Dr. Oz. I know you’re an educated bunch. For me to tear his nonsense apart kind of feels like going hunting with an AK-47…at a zoo.  So respond in the comments section with your thoughts on his points (respond to one, two, or all of them, whichever ones strike your fancy), let’s see who gives the best responses.

If RK’s are the needle, here are some recent gems from the haystack of Oz:

#1- If you have a large bottom, your diet should be high in complex carbs and protein and low in fat. Oz says this type of diet makes it harder for our body to store unwanted fat on our behind.

#2- Raspberry ketone, a natural compound found in red raspberries, helps your body to burn fat by breaking up fats within our cells. It contains the hormone adiponectin that boosts metabolism. Dr. Oz recommends raspberry ketone because we’d have to eat 90 pounds of raspberries to get the same effect.

#3- Dr. Oz went on to say that by taking the raspberry ketone supplements it tricks your body into thinking it’s thin, so hopefully these supplements will get you over the hump.

#4- Just like big bellies, people who carry weight in their upper body do well on a diet that emphasizes dairy says Dr. Oz. This Tex Mex Salad recipe has a decadent sour cream topping. Pair up the salad up with 500mg of L-carnitine, which will stimulate growth hormone and help turn on the mechanism that burns off fat in those specific areas. Eat with an orange since vitamin C activates L-carnitine.

(editors hint: Let’s think about this…a growth hormone boost while eating corn, beans, and oranges…or eating anything for that matter? Anyone want to tackle Endocrinology 101?)

#5- Bonus Fat Buster: Yoga. Do the Downward Dog pose: Get down on your hands and knees and put your bottom toward the sky. Hold yourself up like this as you lift your body up. This pose can help selectively burn fat in the upper bar of your body. Oz says to do for two minutes each day.

#6- Dr. Oz’s protein drink has a secret fat-busting ingredient: white kidney bean extract, it is shown to help prevent carbs from being broken down into sugars and converted into fat in our thighs.


For some good info on the science of RK’s see the H.E.A.T. Stack write up, penned by the former author of this blog quite some time ago.

The short version of RK’s, unapproved by Dr. Oz:

Raspberry Ketones

Enhances fat loss through activation of the TRPV1 receptor, potential mood elevator, positively modulates norepinephrine and hormone sensitive lipase (HSL), aids in reduction of hepatic and visceral fat, helps prevents fat gain, potential pain reducer.

    Ok, I’ll take #1 to get this started.

    Dr. Oz says a diet high in “complex carbs” and low in fat will prevent further fat storage in our large asses.

    And he’s kind of right.

    This high carb/low fat diet will encourage excessive insulin release and promote fat storage in the suprailiac (love handle), abdomen (fat you can pinch, not the deep stuff), and to some degree, although more genetically controlled than the previous sites, the subscapular region (mid back).

    So yes, Doctor O, it’s certainly possible to minimize additional fat storage in the butt region (a safe place to store fat) by corralling it into the midsection which encourages the progression of type II diabetes and Cardiovascular Disease.

    General advice, if a doctor tells you to eat a high carb, low fat diet…for any reason, do it. But do us a favor and get a VAP test done before you start. Then 3 months into your high carb/low fat diet, get another VAP test done.

    Then go on a Paleo diet for 3 months, and re-test the VAP. Compare. Can you guess what you will find? If you can’t guess, I’ll give you my predictions:

    Total cholesterol: Higher, Lower, who cares? Irrelevant**

    Total HDL cholesterol: Increase
    HDL2: Increase
    HDL3: Decrease or no change

    Total LDL cholesterol: Irrelevant**
    LDL1 (pattern A): Increase
    LDL2 (pattern A): Increase
    LDL3 (pattern B): Decrease
    LDL4 (pattern B): Decrease

    IDL: Decrease
    VLDL3: Decrease
    Triglycerides: Decrease
    Lp(a): Decrease
    Apo-b: decrease

    If you ask your doctor for a VAP so you can accurately track the effect of his dietary prescriptions and he/she dismisses/refuses…find a new doctor. If you find a doctor that actually recommends a VAP from the start, you have just found a doctor that will not be asking you to go on a high carb/low fat diet, and you are probably in good hands.

    **Unless you still believe “The Lipid Hypothesis” of high cholesterol causing heart disease, and if you do, fear not…just take a few minutes and relieve yourself of that archaic burden–> http://www.cholesterol-and-health.com/Does-Cholesterol-Cause-Heart-Disease-Myth.html

    And as for #2…

    Fats are not “broken up” within our cells by raspberry ketones. But let’s say that they were, for fun. Fats flux into our fat cells with the help of insulin and Lipoprotein Lipase (LPL). Raspberry Ketones can stimulate Hormone Sensitive Lipase (HSL) which can break down stored triglycerides inside the fat cell into free fatty acids (FFAs) and glycerol. These FFAs could theoretically then be released from the fat cell, transported through circulation, and delivered to the mitochondria of muscle cells where beta-oxidation occurs, or “fat burning”. Which would be great. However, these FFAs could also be re-esterified, which means they are taken right back up by the fat cell to be “re-stored”…and it turns out the overweight body is actually very efficient at this unless instructed otherwise.

    That brings us to the quote “it contains the hormone adiponectin that boosts metabolism”. For anyone familiar with basic biology, it is not only implausible that a fruit contains a unique human adipocytokine manufactured by our fat cells in response to specific hormonal signaling, but it is actually so outlandish to make this claim that I have to question whether Dr. Oz actually said this or if it was a misinterpretation of the columnist summarizing his points. I’m hoping the latter, as I really don’t want Dr. Oz to make it this easy.

    What he and or the columnist may have meant to imply is that raspberry ketones can increase the secretion and expression of adiponectin, which can be verified by at least one study:
    PMID: 20425690. However this was in mice, and while an increase in adiponectin generally appears to be a good thing…a recent study in females linked this hormone’s elevation to alzheimers disease…in humans. Studies implicating negative effects from adiponectin elevation need to be replicated, but this does tell us the jury may still be out on the specifics of WHY adiponectin elevates. Adipocytokines are tricky, most of them are bad news and are pumped into circulation in response to cellular dysfunction…but even the theoretically “protective” ones can have paridoxical effects, another obvious one being leptin. We must also consider receptor/cellular resistance to adipocytokines, it could be that certain “unhealthy” increases in release of adiponectin may bombard the cells in such a way that they become adiponectin resistant.

    Ok, somebody else take over. This post has been viewed about 50x more than a bunch of other posts that have a ton of responses, so stop being shy and dive in. Unless the extra few thousand viewers are all Dr Oz’s lawyers who are patiently waiting and gathering enough data to sue my balls off.

    dr oz doesnt no whate he is talking about weight loss

    what people forget about Dr Oz is he is a surgeon, (maybe was even), hes specialty is cutting and stitching, now turned into a media celebrity, he has endorsed everything and anything, I seldom see him recommending against a product,

    • Your point about Dr Oz is probably valid Anounymous. However it’s worth mentioning many top supplement companies and researchers have praised Raspberry Ketones for well over a decade. RK are in vouge right now but they aren’t new to those of us involved involved in health and fitness.

  4. Reblogged this on thejessewilliams and commented:
    Sorry for the typos, replying on a tiny iPhone while doing cardio is not optimal.

  5. naturally like your web-site but you have to take a look at the spelling on quite a
    few of your posts. Many of them are rife with spelling issues and I
    to find it very bothersome to tell the reality on the other hand I will definitely come back again.
