Lessons from the dubious rise and inevitable fall of green coffee beans

Green-Coffee-Bean-BOGUS

News this week that a randomized controlled trial of green coffee bean (GCB) has been officially retracted from the medical literature signals what is hopefully the end to one of the most questionable diet products to appear on the market in years. Plucked from obscurity and then subjected to bogus research, it’s now clear that the only people that actually benefited from GCB were those that profited from its sale. GCB had some powerful boosters, too. Once it became one of Dr. Oz’s “miracle” weight loss cures, sales exploded following two hype-filled episodes. Oz even did a made-for TV clinical trial with GCB, ignoring the requirements for researchers to obtain ethical approvals before conducting human subject research. Oz’s promotion of GCB was so breathless and detached from the actual evidence that his actions were subsequently eviscerated by Senator Clair McCaskill during televised hearings on weight loss scams. It’s a long, sordid, ugly and yet entirely predictable story. (more…)

Dr. Oz and the Terrible, Horrible, No Good, Very Bad Day

Not Dr. Oz's usual television audience

Not Dr. Oz’s usual television audience

Dr. Mehmet Oz is one of the most well-known, and possibly the most influential medical doctor in America. The Dr. Oz Show is broadcast in 118 countries and reaches over 3 million viewers in the USA alone. When Oz profiles a product or supplement on his show, sales explode – it’s called “The Dr. Oz Effect”. Regrettably, Oz routinely and consistently gives questionable health advice, particularly when it comes to weight loss products, where Oz regularly uses hyperbolic terms like “miracle” for the products he profiles:

  • (On green coffee extract) — “You may think magic is make-believe, but this little bean has scientists saying they found the magic weight-loss for every body type.”
  • (On raspberry ketone) — “I’ve got the number one miracle in a bottle to burn your fat”
  • (On Garcinia cambogia) — “It may be the simple solution you’ve been looking for to bust your body fat for good.”

Dr. Oz has profiled so many dubious health strategies that “The Dr. Oz Effect” more accurately refers to the wasted time, effort and finances of any consumer that actually follows his health advice and purchases the steady stream of “miracles” that Oz endorses on his television show. Not surprisingly, Science-Based Medicine is probably Oz’s most persistent and tenacious critic. It’s not just that he’s high profile – it’s that Dr. Oz is a bona fide physician who ought to know better, but chooses to ignore science in favour of hyperbole. It’s the antithesis of what a health professional should be doing. And this is the root of the Oz problem: Oz can give good advice, but he regularly combines it with questionable statements and pseudoscience in a way that the casual viewer can’t distinguish between the science and the fiction. So when Oz calls something a miracle – people listen. Even when miracles show up several times per year. (more…)
