Host of “The Dr. Oz Show”, Dr. Mehmet Oz was scolded by the senators on Capitol Hill for his promotion of bogus weight loss products. Products that do not have a lot of scientific evidence such as green coffee beans were regarded as magic diet pills on the show.
“A small study published in 2012 found chlorogenic acid, the main ingredient in green coffee beans, helped 16 human participants lose, on average, 18 pounds over 22 weeks. But another study on chlorogenic acid in mice found that the acid did not help mice lose weight and in fact, increased their insulin resistance.”
“In 2011 meta-analysis of three studies on green coffee extract found that on average a five-pound loss among study participants. But the three studies were short term and has a small number of subjects. The authors of the study, “More rigorous trials are needed to assess the usefulness of GCE as a weight loss tool.”
Oz says he uses “flowery language” to sell and market products on the show but he believes in them so much he has given them to his family.
Thanks to brand new scientific research, I can tell you about a revolutionary fat buster,” Oz said on his show in November 2012 with the words “No Exercise. No Diet. No Effort” on the screen behind him. “It’s called Garcinia cambogia.”
A 1998 study of 135 participants found Garcinia cambogia did not result in weight loss besides the placebo effect. But a 2013 meta-analysis of Garcinia cambogia studies emphasized on its inability to result in weight loss, saying its benefits “remain to be proven in larger-scale and longer-term clinical trials.” T
Oz testified Tuesday that he could not be held responsible for what certain companies say online about the products. He said he’s toned down some of his language and will publish a list of products he thinks really can help people lose weight.
“To not have the conversation about supplements at all however would be a disservice to the viewer,” Oz said in a prepared statement after the hearing. “In addition to exercising an abundance of caution in discussing promising research and products in the future, I look forward to working with all those present today in finding a way to deal with the problems of weight loss scams.”
