Before & After: 16 Amazing Celebrity Weight Loss Transformations

4. Jonah Hill – 30+ pounds

The Superbad actor is enjoying his new super slim figure, which was something he did for another one of his projects, 21 Jump Street. According to a close source, he did so with the help of a nutritionist and a trainer, Us Weekly reported in 2011.

That may have been a while back, but Hill has only continued to lose weight throughout the years. Just last year, he flaunted his trimmer figure and looked quite dapper walking down the red carpet at the 2018 Met Gala.
