Jamie Kennedy helps girlfriend Jennifer Love Hewitt with her diet by setting a good example, the actress told Shape magazine.

"He's inspired me to improve my diet," she says. "He has a salad with every meal, plus lots of fruit, fish, and vegetables."

Jennifer says she returns the favor by setting a good example for him, too.

"Last summer we were in Monaco. Every morning we ran for 40 minutes through the streets of Monte Carlo," she says. "It was an amazing way to see the city. Now when we travel, we try to explore the places by running."

"I fall asleep feeling beautiful," she says. "Then, in the morning, before I leave the house, I say five things I love about myself, like 'You have really pretty eyes.' That way I can go out into the world with that little bit of extra confidence. It's a feel-good protein shake in my back pocket in case someone messes with me that day."

Good for her! Yet Jennifer admits she still deals with insecurities.

"I'm a girl, after all! 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.' "

Now that is a great philosophy.
