You probably remember when Jonah Hill broke onto the movie scene.
He had fleeting appearances in 40-Year-Old Virgin and Click, before having a more prevalent role in Knocked Up and starring in Superbad.
The latter shot him into to stardom and everyone became accustomed to his comedy, though there was a particular physical feature people noticed.
It's been no secret that Hill has gone up and down in weight over the years, seemingly losing it at will.
Once again he's shredded a huge amount of weight, with his 21 Jump Street co-star Channing Tatum to thank for the motivation.
Tatum, once upon a time, was that cheesy rom-com, heartthrob type and had the annoyingly chiseled body to go with it. Because of that, Hill rang him up to ask for advice, to which he got a very frank and straight-to-the-point reply.
"I wanted to get in better shape, so I called Channing Tatum and said, 'Hey, if I ate less and go to a trainer, will I get in better shape?'." Hill said during an interview on The Tonight Show. "Yes, you dumb motherfucker, of course you will. It's the simplest thing in the entire world."

For his role in the 2016 film War Dogs, the 33-year-old gained a reported 40 pounds, but now after being pictured at the weekend it looks like he's lost it all and more.
Bit of motivation to get the summer body? Or are you still going to carry on eating unhealthy food, drinking beer and not exercising?
I'm with the latter, to be honest.
