Mehmet Oz's controversial health claims, from the HCG diet to green coffee extract

It was a surprising pick among many surprising picks. This week, President-elect Donald Trump announced his choice to head the Centers for Medicare and Medicaid Services: Dr. Mehmet Oz, who is as famous for the “America’s Doctor” moniker as he is for the number of dubious health claims he’s made from that perch over the years. 

Perhaps it shouldn’t have been surprising. After all, Trump endorsed Oz in his unsuccessful Senate bid in 2022, and in 2016 Trump appeared on Oz’s show to undergo a “surreal” on-air physical in lieu of sharing his medical records with the public. Plus, Melania Trump likes him.
