Jennifer Love Hewitt may be rockin' a bikini on our cover, but she has the same insecurities as every woman.

"I'm a girl, after all!" says the 30-year-old actress. "For the most part, yeah, I'm happy with my body, but there are days when I'm like, 'Ugh! Really? Why is it so hard to fit into my jeans?' That's when I say to myself, 'I look this way because I'm supposed to. If we all looked the same, we'd be boring.'" Here, she reveals her stay-healthy-and-happy strategies as well as her work out that she uses to stay slim and confident.

Healthy eating tips # 1: Put your fridge on a diet To keep her food choices healthy and fresh, Jennifer hits the super-market every two days. "Instead of piling up food in my fridge that says 'Come eat me!' I keep enough for only a couple of days. And I rarely have treats around that might tempt me late at night, which is when I usually crave something really fattening. What am I going to do? Drive out at 11 at night just to satisfy a craving? No, that's crazy."

Healthy eating tips # 2: Always eat lunch It's no secret that over the last few years, young actresses have become fixated on being super thin, a trend Jennifer finds really disturbing. "Hollywood used to revolve around women with curves, like Liz Taylor and Marilyn Monroe," she says. "But now it's so different. Not that long ago, I went to this celebrity luncheon, and I was the only person in the room eating. The other girls looked at me like I hadn't gotten the memo, but I was hungry! All of these girls were afraid that if someone saw them eating, it would be a disaster. It makes no sense at all."
