I really feel like food is a drug, says Jessica Biel

Melbourne, July 24 (ANI): Jessica Biel believes that food is like a drug.

"I really feel like food is a drug. When I'm not eating properly, I have less energy - my body looks different, which means it looks different on film. I look different through my face. I think about those kinds of things and I want to feel more than it is the vanity part of it," the Daily Telegraph quoted her as telling the OK! magazine.

"I want to feel I can go 18 hours on set, if we have to, working, working, working, and feel confident about my health. So when I'm working, I'm really disciplined. When I'm not working, I'm very undisciplined," she added.

The 28-year-old beauty revealed that she loves tucking into her favourite foods, but is restricted to what she can eat.

"I love food, love it. But I'm really disciplined and boring most of the time. It's so true!" she added. (ANI)
