Why did Rebel Wilson decide to lose weight?
Rebel’s weight loss was kick-started when she shed eight pounds in just a few days while learning the tough dance routines for the film Cats.
She was then spurred on to "avoid the sugar and junk food" after a particularly festive season.
But her decision to further improve her health and combat her "overeating" was steered by her career too.
She told The Mirror: "I literally feel as if I have to physically transform because it's very difficult for people to imagine [me in serious roles] for some reason – even though we're in a very imaginative industry.
"I feel that I physically have to show you that I am different and I am transformed in order to help transform my career."
Adding: "I still love comedy, but I did train originally as a dramatic actress which people forget."

How often does Rebel Wilson workout?
Her personal trainer does put Rebel through her paces. Jono Castana Acero commended her for "putting in the yards seven days a week" on Instagram, although Rebel admits she does take days off.
When she's not crushing HIIT workouts and resistance training she gets her steps in.
So whether it's hiking, running, or walking Rebel makes sure she hits the 10,000 step mark by the end of the day.
Oh, and did we mention she loves TRX, boxing, and flipping tyres too?

It hasn't been easy
She may look incredible but it's not been a simple journey for Rebel.
She summed it up in an inspiring Instagram post when she wrote: "Even if you have to crawl towards your goals, keep going x it will be worth it.
Try and give a little bit of effort each day... I know some days are frustrating as hell, you feel like giving up, you get annoyed at the lack of progress...but good things are coming your way."
