Celebs May 12, 2016 By Vincent

Although we sometimes forget it, celebrities are humans just like us and their weight, body size and shape can fluctuate depending on lifestyle, health or personal habits. Here, we take a positive look at those stars who altered their habits to undergo dramatic changes and have managed to get themselves in better shape.

Whether through better diet or increased exercise, these guys offer up inspiration for those of us who struggle with keeping the pounds off.

1. Chris Pratt

Superstar actor who became part of the Marvel film universe when he took on the role of Starlord in Guardians of The Galaxy but it was as the chubby, playful Andy Dwyer in Parks and Recreation that he first really caught the public's attention.


When deciding to go up for a role in The Hurt Locker, Chris thought he needed to get in shape to land it and when producers of the aforementioned Marvel flick asked if he could do it again, he went one better. Now a fully fledged action star who fronts the reboot of the Jurassic Park franchise Pratt keeps himself fit and healthy.

2. Jonah Hill

Since bursting into public consciousness as the rude, crude teen in Superbad, Jonah Hill has transformed into an Oscar-nominated actor who has worked with the likes of Martin Scorsese.
