Oprah Winfrey dubbed Dr. Oz “America’s Doctor.” well, “America’s Doctor” just appeared before a Senate Hearing Committee to discuss his endorsements of diet supplements and their supposed “miraculous” benefits. And what came out will shock you.

It seems there is a Dr. oz effect. Apparently, once Dr. oz discusses a new miraculous (and yet scientifically unresearched) diet supplement, scammers come out of the woodwork offering the supplements and raking in the money. We Americans trust “America’s Doctor” and his opinions. But according to Dr. oz himself, these miraculous results are more hyped fiction than truth.

“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.”

Dr. Oz considers himself a “cheerleader for his viewers. But we are expecting more than a cheerleader. We are expecting a well- researched, medical opinion with foundation. Weight loss products like green coffee beans and Garcinia Cambogia have been researched and found to have less than stellar results. Garcinia Cambogia is shown to have only a placebo effect and while some drinkers of green coffee beans have been found to lose 5 lbs., which is less than miraculous, it has been found to have no weight loss effect on mice.

So, “America’s Doctor” or not, it is clear that Dr. oz should be promoting the only proven effective way to lose weight, watch what you eat and exercise. Want to lose weight? Burn more calories than you take in. Any other no exercise, easy weight loss methods are likely to only lighten your wallet.
