Why are we FAT?

In ten years, Americans put on a  billion pounds.  The step-up in weight started in the 1980s.  Why are we turning into a plus-size nation?

The New Yorker gives a good overview of recent books on the subject, calling out the usual suspects - evolutionary forces, psychology, financial motivation and corporate manipulation.

Meanwhile, progress is being made on two fronts.

Scientists have made "brown" fat from mice and human cells.  Brown fat is good fat - it turns our bodies into heat producing machines and burns white fat.

And common allergy drugs have been found to reduce obesity in mice, by modulating inflammation in fat tissue.
