Kelly Osbourne Weight Loss: Hungry People Are 'Miserable'

Kelly Osbourne has suggested that happiness is the quickest path to weight loss.

Osbourne, 28, has had her fair share of ups and downs. In the past, she struggled with an addiction to painkillers and was admitted into rehab twice. But Osbourne has since changed her life around.

Now 5'2" and only 112 pounds according to reports, Osbourne has lost five dress sizes since her 2009 appearance on "Dancing With The Stars." But when asked about her weight loss, the star has said that it is not losing weight that makes you happy.

"People think I lost weight and then got happy, but that's not how it works. You have to get happy first," the star said during a recent interview with InTouch magazine. "I made a life change, and the weight loss was an amazing perk."

Osbourne suggested that she never imagined she'd be the skinny girl that likes to work out, but now says that exercising is something that she looks forward to.

"[Working out] is something I really enjoy doing," she said. "I never thought I'd be that kind of girl."

Osbourne added that she also maintains a fairly healthy and consistent diet, which helps her to maintain her weight.

"For breakfast, I will eat either cereal or a little omelet thingy made with egg whites, mushrooms and spinach. Lunch is usually a salad or a turkey burger. And then for dinner, I'll have brown rice with vegetables and some kind of meat," she told InTouch.

The star's workout routine includes up to a half hour of cardio with a mix up of pilates, yoga, or circuit training. And while she tries to go up to five days a week, Osbourne also admitted that she had her "cheat" days.

"Never deprive yourself of anything, because then you get angry about it," she advised. "People who are hungry are miserable."
