I thought it was a joke. Silly Mary.
When I first read about this on 15 minute lunch, I didn't take it seriously. But Back in skinny jeans pointed me to an article in the NY Times that gave more information. (They've done scientific tests. Well then.)
It still sounds like some kind of elaborate leg-pull. As one of the scientists said, "It is almost too good to be true."
The idea is one that my inner slug devoutly subscribes to: it should be possible to get thin-and-fit without having to do anything. If this burns fat and builds bone density, that's good enough, right? Maybe it'll work my heart and lungs too, without my having to bother.
Yeah, right. I'm off to aerobics now.
