What to eat to make positive changes and get in shape for swimsuit season

That winter comfort food isn't so comforting right now is it?

But don't despair: You can lose the pounds -- and the layers.

"No matter what kind of jiggly, wiggly or flabbiness you have over your six-pack, just know there are abs underneath all that," says L.A. celebrity nutritionist Rehan Jalali.

"It's up to you to bring them out. Now it may be harder for some of us ... but it can be done."

Jalali has worked with Sylvester Stallone, Ben Affleck, Debra Messing, Matthew Perry, Nicole Scherzinger, Joel Madden and others.

"Most of the singers and movie stars I work with generally have only a month or two to get super lean for a video shoot or movie, so having a whole three months is plenty of time to see great results."

By the time summer rolls around, you could be hot -- and healthy.

"Since spring symbolizes change, it also can translate into body change," says Jalali, of rehanjalali.com.

Pack up the potato chips and start immediately.

Set specific goals and an exact deadline to achieve those goals, like drop 15 pounds by July 1, so there is positive pressure to achieve that goal, advises Jalali, author of The Six-Pack Diet.
