For anyone in the comments arguing it's not a big deal that Oz -- widely considered a top cardiothoracic surgeon -- promotes dishonest weight-loss miracles ...
He's correct in that it would be miraculous if this nonsense worked.
... or that his bad diet advice doesn't negate his ability as a heart surgeon, here's why you're wrong: Diet and exercise play an enormous role in heart surgery, both pre- and post-op, as well as the overall health and function of your heart. Heart doctors like Oz know this and typically recommend very specific dietary and exercise guidelines for their patients to follow. That being said, if one of the top cardio docs in the country is recommending diet advice in the form of a pill (which he loves to do), then even some smart people are bound to follow said advice solely based on the giver's credentials, no matter how bogus the science is behind it.
I think we need some quotes around the word "science" here.
