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."
