Could there be a 'skinny' gene?

A study in mice reveals a gene that could explain why some people quickly pack on pounds -- and others can eat what they want without consequence.

Researchers at Boston Children's hospital identified a gene that controls how quickly calories are burned. They found mice without the gene gained more weight than those that had the gene intact -- even though they ate the same amount of food.

The only way to keep those mice at a normal weight was to feed them ten to fifteen percent less than the other mice.

As adults, the mice with the deleted gene developed monstrous appetites.

So far one human, a severely obese child, has been found to have the same gene mutation.
