How's the saying go -- starve a fever? Feed a cold? I can never remember. But here's some interesting news: A common cold bug (AD-36) not only infects your respiratory system and makes you feel like hell, it also causes your fat cells to get hungry and suck up all the fat they can find.

Pretty wild, right?

Scientists found that up to 1/3 of obese people tested positive for the virus, compared to 11 percent of those who maintained a healthy weight. While these findings don't really apply to you and me -- because what can you do to avoid a common cold virus, beyond becoming Bubble Girl? -- it's one piece of the obesity puzzle for scientists.

So what should you do if you catch a cold? Take care of yourself by getting lots of rest and drinking plenty of fluids. And when you feel better, take care of yourself by eating a healthy diet and exercising regularly.

Oh, and wash your hands. It is cold and flu season, after all.
