Losing weight while you're a celebrity has its pluses and minuses. You have access to trainers, chefs, and expensive treatments. However, you always have the unforgiving glare of the media on you...

Jonah Hill rose to fame in Superbad. He reminded us all of that chubby class clown in high school. The funnyman, however, turned heads after his appearance at the Toronto International Film Festival, where he strutted down the red carpet looking sleek and trim in a fitted black suit! Though everyone agrees that women are more heavily scrutinized than men for their appearance, Jonah said he was shocked how many more roles he was offered after the weight loss.

Keely Shaye Smith always seems to have lived in the shadow of her much more famous husband, Pierce Brosnan. Over the years though, fans have noticed that her weight has fluctuated a tremendous amount. In recent times, the loyal wife of the former Bond man changed her lifestyle and diet drastically and lost a whopping 120 pounds in the process. She was dedicated to exercise and eating well. Brosnan has always stuck by his wife's side, through thick and thin.

Ever since she captured America's heart on the show Newlyweds: Nick and Jessica, Jessica Simpson has been considered a blonde bombshell. She showed off her killer curves when she sported iconic Daisy Dukes for her role in The Dukes Of Hazzard reboot movie. But like most women, after two pregnancies, she gained a little bit of baby weight. With the help of Weight Watchers (and a trainer), Jess dropped 80 pounds and got back into fighting shape.

Love her or hate her, one thing everyone can agree on is that Rosie O'Donnell is an open book! She came out very publicly on her eponymous talk show Rosie back in 2002, in order to raise public awareness about challenges facing LGBT couples who wish to adopt. She has spoken about always struggling with her weight, but in 2013 took the drastic step of deciding to go under the knife for gastric bypass surgery. She lost 70 pounds in two years!
