Jason Segel showed off his drastic weight-loss transformation while out and about in Boston on Oct. 17. The How I Met Your Mother actor is barely recognizable after shedding pounds for his upcoming flick, Sex Tape.
"I've just been living healthy, exercising, eating right -- no more midnight pizzas," he told Us Weekly. "This time when I take my shirt off, I've made a promise to myself: It doesn't have to be funny."
Good for Jason for wanting to be fit and healthy, but we hope he is dieting safely. See his dramatic transformation below:
