Vegetable Fiber

Jen Kersey (Season 2) isn't afraid to say she has a problem. Yes, it's true. She can't put down the fiber.

Morning, noon, and night, she's snacking away on foods that fill up her stomach and help keep the pounds off, post-show.

Sitting down for a chat, she confessed that her biggest secret to losing weight was, "vegetables, vegetables, and vegetables."

But she didn't stop there.

"Make your sandwiches with high-fiber bread," she says. "It contains about 45 calories a slice. That way, you can have two slices of bread."

When it comes to treats, Jen goes for the fruity fiber. "If you have a sweet tooth, eat fresh pineapple. Its sweetness is unbelievable!"

So next time, you're shopping, do it Jen's way. Fill your cart with foods that can keep you on the weight-loss track: fruits, vegetable, and multi-grains.

But remember, we warned you. Too much of a good thing…is a good thing.
