Yo-Yo dieting may not be as bad as you think.

FOX's Colleen Cappon reports in today's "Housecall for Health"...

Are you a yo-yo dieter?  Does your weight go up and down?

Research says yo-yo dieting is better for overweight people than not dieting at all.  Scientists from Ohio University placed mice on alternating high-fat and low-fat diets, and they lived 25% longer than those on a steady diet that kept them obese.

The yo-yo dieting mice had better blood glucose levels and fewer harmful protein molecules linked to diseases like diabetes, heart disease and cancer.
