Kelly Osbourne is an "emotional eater".
The 'Fashion Police' host - who is known for her fluctuating weight but is now a small UK size 8 (US size 4) - admits she turns to food whenever she is upset by something but has gradually learned to take control of her diet and exercise regime and food urges.
She said: "I'm an emotional eater. When I get upset, my diet goes out the window. Now, I've finally learned how to eat properly and I've found ways to make working out a fun part of my life, like getting my friends to do it with me."
Though the 28-year-old star - who is dating vegan chef Matthew Mosshart - watches what she eats, she has a "cheat day" every week and knows depriving herself when she craves a particular food would only make her miserable.
She added to Closer magazine: "I have one 'cheat' day a week where I eat whatever I want. I usually indulge with pizza and cheese - I love brie - and cookies. But when I'm full, I stop eating.
"I've put a lot of hard work into my body over the years and, in the process, I've learnt to love myself. Never deprive yourself of anything because they you get angry about it. People who are always hungry are miserable."
