Garcinia Cambogia Review: As Seen On Dr. Oz

When Oz called Garcinia cambogia “the newest fastest fat buster” I nearly fell out of my chair.

Since there’s a huge amount of interest in any weight loss supplement recommended on the Dr. Oz show, we do our best to feature most of them here on Accordingly, we’ve covered more than a handful already (including green coffee extract, raspberry ketones and Satiereal to name a few), so at this point, I really should not be surprised by anything Oz says.

And yet, I continue to be.

Because Garcinia is not new.

Not by a long shot.

And when I heard this..

“Thanks to brand new scientific research, I can tell you about a revolutionary fat buster. It just might be the most exciting breakthrough in natural weight loss to date. Revolutionary new research says it could be the magic ingredient that lets you lose weight without diet and exercise. Could Garcinia cambogia be the fat busting breakthrough you’ve been waiting for?”

I shook my head in disbelief.

See, a lot of people hang off every word of Oz’s – they respect him, and they turn to him for answers.

The guy has, after all, some pretty impressive medical credentials after all. He knows about science. He knows about clinical studies. He knows about methodological flaws and small sample sizes. He knows about the placebo effect. He knows about conflicts of interest and how they can impact study results. Yes, he knows ALL this stuff, but chooses to ignore it and instead, provide rosy, exaggerated “pictures” of the weight loss supplements he features on his show.

Truly, Dr. Oz has done more than drunk the Kool-Aid. He’s guzzled back the entire jug.

If you’re an Oz fan, you’re probably starting to get a little annoyed right now. I bet you’re thinking, “who the hell is this guy and why should I listen to him?”

Well, that’s understandable – Oz is a doctor and a celebrity.

But let’s make one thing clear; just because Dr. Oz says it is “so”, doesn’t make it any more “so” than me saying it is not so makes it not so.

The measure of Garcinia cambogia’s “effectiveness” can only be gleaned from reviewing the available clinical studies.

This review of garconia cambogia will take a closer look at those, so you can make up your mind.

What is Garcinia Cambogia?

As you probably already know, Garcinia cambogia is a fruit native to India. The ingredient to which the “fat burning” effects are attributed is something called “hydroxycitric acid” (or HCA), which is extracted from the rind, and can inhibit ATP citrate lyase, a key enzyme in the synthesis of fatty acids.

Garcinia cambogia, hydroxycitric acid, HCA and Citrimax all refer to the same thing: hydroxycitric acid.

On the face of it then, Garcinia cambogia – via its hydroxycitric acid content – may have some use for weight loss.

What do the Studies on Garcinia Say?

Well, one large scale study (performed on 135 people) published in the Journal of the American Medical Association in 1998 (so much for “newest”, huh?) concluded…

“Garcinia cambogia failed to produce significant weight loss and fat mass loss beyond that observed with placebo.”

Perhaps more damning is the systematic review of the clinical data supporting Garcina cambogia’s effects on weight loss, which was published in 2011 in the Journal of Obesity. It concluded…

“The evidence from RCTs (randomized clinical trials) suggests that Garcinia extracts/HCA generate weight loss on the short term. However, the magnitude of this effect is small, is no longer statistically significant when only rigorous RCTs are considered, and its clinical relevance seems questionable. Future trials should be more rigorous, longer in duration, and better reported.”

In other words, some studies show Garcinia extracts work to some small extent, but for those that do, methodological flaws and small sample sizes call the reliability of the data into question.

Even if you want to interpret this data in the most generous way possible, there’s nothing here to justify Oz’s “newest fastest fat buster” comment.

However, we’re not finished with Garcinia yet.

A Newer Form May be More Effective!

A newer form of HCA, called Super Citrimax, was trialled at the Georgetown University Medical Center in 2004 (you may recall seeing a clip of the study’s lead author, Dr. Preuss, highlighted on the Oz show).

This study demonstrated a 5.4% decrease in body weight over the 60 day trial period. For a 150-lbs woman, that equates to 7.8 pounds of weight loss in two months. For a 200-lbs man, 10.8 lbs.

The main issue with this study is that completely contradicts Oz’s statement, that Garcinia may be the “magic ingredient that lets you lose weight without diet and exercise”.

Because as you can see if you review the study abstract yourself, participants very clearly did both; “participated in a 30 min walking exercise program 5 days/week” and were restricted to a 2,000 calories per day diet.

The question then becomes…

“How much of that 5.4% loss of body weight is entirely attributable to the diet and exercise that accompanied the supplementation of Super Citrimax?”

Could you lose 8 pounds in 2 months simply by restricting your calories and exercising? I would say you could… without the aid of Garcinia. And even if it helps, well, at the risk of sounding like a broken record, there’s nothing here to justify any of the statements made by Oz.

It’s no miracle.

Affordable, But Not Cheap

The other thing Oz’s experts highlighted was Garcinia’s cheap cost.

Guess what?

It’s not THAT cheap.

For example, sells the 90 capsule Now brand Super Citrimax for just under $16. To duplicate the dose found helpful in the Georgetown clinical study (2800 mg of standardized extract divided into 3 doses) , you need to take 6 caps per day. So you need two bottles per month. That’s $30. Affordable maybe, but hardly cheap.

Bottom line on the Garcinia Review?

It’s far from new.

Initially it was pushed by the supplement retailers as a carb blocker and it did sell well for while, until customers found the promised results didn’t materialize. Then it stopped selling. I’m sure it will sell well now, due to Oz’s recommendations, until once again, the promised results fail to materialize.

If in doubt, review the clinical study results. They are what tell the tale.

Sorry to say, but…

This is an EPIC fail by Dr. Oz.

Try Garcinia for Free (Almost!)

In the period after Oz’s endorsement of Garcinia, I’ve seen a ton of unscrupulous people taking advantage of a desperate audience by selling garcinia products for anywhere from $40-$70.

This is ridiculous.

If you still want to experiment with Garcinia after reading this review, you don’t need to spend much. In fact, you can experiment for about $10.

  1. I am not happy with the fact that in order to read the whole article I have to SHARE or LIKE this page. I am in agreement that Dr. Oz is probably not up front and who knows getting a cut of the profits for these pills. But I could not even see a portion of the article presented here because the SHARE button kept getting over the sentences and then I couldn’t finish the article because I refuse to be held hostage by such a ploy

    • Jo Hanna,

      We’re sorry you feel that way. We feel it’s a small trade off in exchange for the high quality, free content that we provide. It takes a lot of work and a lot of time to do the writing and the research for the articles we post, and we feel it’s a small price of which to ask from our visitors. Social signals like the share and “like” buttons help tell both search engines and social media that our content is worthwhile and engaging. You’ll notice that the article is “locked” more than half way through, so you are always free to “not” share it, should you not think it’s worthwhile.

    • I agree with Jo Hanna. I have been coming to this site for more than a decade and to now be forced to share or like just to read is absurd and a big turnoff to a once beloved site. Facebook seems to manage just fine without holding its visitors hostage or forcing them to take some sort of reciprocal action if they want to read a page or a post. If they can do it, so can this little, tiny site. And if not, there are always paid banner ads!

      • AJ… um, Facebook has a somewhat different business model than we do, and I think the comparison is more than a little off-base. The fact that we’re a BILLION times smaller than Facebook means we’re less likely to be able to operate the same way they do. We were simply asking for people to share our content in return for reading it. Given the time it takes us to research and write an article, we thought that was pretty fair. Anyhow, the entire discussion is moot; we’ve completely removed this functionality so it’s no longer necessary to “share” or “like” anything in order to read it (you didn’t have to, so I’m a little unsure of what the issue is). We’d still love it if you did, of course. :-)

  2. I didn’t have to “share” to be able to read the whole article. I’m not sure what Jo Hanna is referring to but I get email notices about articles then click to read more. Anyways, I had already noticed something funny going on with Dr. Oz. I was more familiar with than with who he actually was & his credentials before he got popular with Oprah. I watched his show a couple of times recently & half the time the information sounded good with basic science to back it up but the other half of the time it felt almost like an advertisement. It scares me how people ooh & aaw over what he says, like it’s golden. I only trust people as far as I can throw them, lol.

  3. I didn’t have to “share” either. I just pressed the g+ button and read the whole article. Perhaps she should try again. No ploys here, Jo Hanna. Try again, sweetie.

    Anyway, I used to record the Dr. Oz show, but when he started advertising his miracle finds for weight loss, I stopped. I saw this show on the Garcinia last year and right away, sought Paul’s research on it and sure enough, it was not an effective product. I wish I had done that on the Sensa product. I got ripped off big time with that one.

    Nothing compares to diet and exercise. I have since started on the 5:2 diet with my husband and so far I’ve lost 14 lbs. and he’s lost 10 lbs. We eat whatever we want for 5 days and Mondays and Wednesdays, I eat 500 calories and he gets 600 calories. We’ve gotten so used to it, that we look forward to our “fast” days.

    Thanks for all you do, Paul.

    • I’ve lost around 11 poduns in a month with this product by combining with a low carb diet and exercise. I found that this product is excellent at suppressing my appetite when I take it anhour minutes before eating. I always take it with a big glass of water, which I think also helps me feel full. I get full very quickly which is exactly what I wanted from this product.

  4. I have used Vital Mend Garcinia Cambogia for about a month and a half and with exercise and eating healthy I have now lost 17 lbs – not a huge loss but I am thrilled with the results – they have worked for me – I worked out and ate healthy for a few months before taking the supplement and hardly lost anything – I am 42 so at that age, seems harder to lose weight! But using it along side of my exercising and eating well it has worked for me – I am on blood thinners and cholesterol pills, I had a Stroke last year and after checking with my Pharmacist I was given the okay – I have had no side effects and lots of success – the key to ANY weight loss success story – you NEED to exercise and you NEED to watch what goes in your mouth :)
