8. Graham Elliot
They say you should never trust a skinny chef—but that old saying doesn’t quite apply to celebrity chef Graham Eliot. As one of the well-known hosts of MasterChef, he stunned audiences when he dramatically slimmed down, dropping a remarkable 150 pounds. In 2013, Graham underwent weight-loss surgery, but his transformation didn’t stop there. He’s managed to keep the weight off through regular exercise, with jogging playing a big part in his routine.
