Sisyphus and his endless task
My BMI is 21, but my e-mail and Facebook accounts must think I’m fat. I am constantly bombarded with messages about miracle weight loss solutions, and most of them are diet supplements featured on the Dr. Oz show. Back in December I wrote an article about Garcinia cambogia, Dr. Oz’s “newest, fastest fat buster.” I made this prediction: “I confidently expect another “miracle” to supplant Garcinia in the Land of Oz in the not-too-distant future.” I was right. The e-mails about Garcinia have recently been outnumbered by e-mails about a new Dr. Oz miracle weight loss supplement, forskolin. Actually, I think he discovered forskolin before he discovered Garcinia, but the forskolin propaganda seems to have reached a critical mass in the last few weeks.
The Land of Oz
A Dr. Oz episode on the “Rapid Belly Melt” aired a month ago, on May 5. He set fire to a paper representation of a fat belly to show how forskolin “works like a furnace inside your body.” The paper ignited, went up in flames, and revealed a non-flammable model of muscle tissue inside to show how forskolin burns fat, not muscle, and to illustrate how quickly it works.

Women make up a majority of Dr. Oz’s audience. The majority of women would like to lose weight. That is a match made in heaven, a marketer’s dream. And Oz has never hesitated to exploit that fact to increase audience share, playing fast and loose with sensationalized evidence instead of giving his viewers science-based advice.
Garcinia cambogia extract (GCE) comes from a tropical fruit from India and Southeast Asia. The active ingredient, hydroxycitric acid (HCA), is said to block fat and suppress the appetite.
Dr. Oz has promoted a series of weight loss supplements on his show. Raspberry ketones were presented as a fat-busting miracle, then green coffee bean extract was touted as “magic,” “staggering,” and “unprecedented.” And now both of those miracles have apparently been superseded by an even greater miracle: Garcinia cambogia extract.
Dr. Oz calls it “The newest, fastest fat buster.” A way to lose weight without “spending every waking moment exercising and dieting.” “Triples your weight loss.” “The most exciting breakthrough in natural weight loss to date.” “The Holy Grail.” Oz claims that “Revolutionary new research says it could be the magic ingredient that lets you lose weight without diet or exercise.”
All that sounds too good to be true, and it is. Garcinia probably does work to some extent to improve weight loss, but the evidence doesn’t begin to justify such grandiose claims. (more…)
I’m frequently asked, “Is what that ad says really true?” Three recent inquiries have been about products advertised in Scientific American. An ad may acquire a certain cachet by appearing in a prestigious science magazine, but that doesn’t mean much. Scientific American’s editorial standards apparently don’t extend to its advertising department. I remain skeptical about the claims for all three of these: Juvenon, the StressEraser, and the ROM exercise machine. I discussed the ROM machine last week.
This product is advertised as “The Supplement That Can Slow Down the Clock on Aging Cells.” Andrew Weil also sells this on his website. It supposedly helps keep your mitochondria from decaying, promotes brain cell function, sustains energy levels, and is a powerful antioxidant.
The first time I noticed an ad for Juvenon in Scientific American I wrote the following letter to the editor: (more…)
