Jonah Hill, 21 Jump Street – 36 Pounds

Jonah Hill is a crowd favorite who started in comedic projects like Superbad and This Is The End to serious ones like Maniac and True Story. You might not know this, but Hill was required to lose weight for 22 Jump Street and then put on 40 pounds for War Dogs.

After that, Hill made it his goal to be healthier, and his weight had dropped 40 pounds due to his newfound athleticism. He owes his success to the gym and a dietician. We hope the Oscar-nominated actor’s health consciousness inspires youngsters to do the same.
