Ethan Suplee – 300 Pounds

Actor Ethan Suplee might have the most incredible celebrity weight loss story of all time. After the former Boy Meet World actor hit 550 pounds, and doctors needed to use a special scale to weigh him, Suplee knew he had to turn his life around. “I was utterly horrified,” Suplee told The Today Show.

Although he’s now lost 300 pounds and started a weight loss podcast, American Glutton, Suplee says the formula is simple: diet, exercise, and determination win the day. “The main thing I had to do was make sure I didn’t eat more calories than I expended each day. And guess what? Foods that were nutritious — dark leafy greens, chicken, salmon — also tended to be much lower in calories than, say, a two-patty Super Star,” Suplee explained.
