Top swimsuit model Marissa Miller revealed how she keeps her body in shape - eat naked!

Marissa Miller is known as a great swimsuit model and one of the models in yearly Victoria's Secret fashion shows. Miller also graced a lot of magazine covers like Sports Illustrated where she flaunts her beautiful body. She revealed her diet regimen in the January/February 2012 issue of Women's Health magazine.

"Eating smart is all about having an awareness of your body. The most obvious way to do that is by seeing it," said Marissa who is casted in the latest movie R.I.P.D. with Ryan Reynolds. She also added, "So when you're trying to lose weight, spend more time wearing less. I don't think I could eat a plate of nachos naked - could you?"

Miller's other tips are more run of the mill; have brown rice and quinoa in the fridge to eat with vegetables and get small, individually wrapped chocolates to eat when a craving calls instead of large desserts.

Unbelievably, the top model gained weight when she married music producer Griffin Guess. She said that when she's in love, she tend to eat more.

Currently, the swimsuit model is filming her first movie, R.I.P.D., opposite Jeff Bridges and Ryan Reynolds in Boston, and despite her ability to bare nearly all, she says she's shy.

"I'm very shy. ... I know it's weird for a person who models lingerie and swimsuits, but I don't like to be the center of attention!" she said.
