LATEST DIET CRAZE: AIR DIETING..WTF?

This is nuts ... Apparently the new French diet craze is "L'Air Fooding." It's where you pretend to eat ... but don't actually put any food in your mouth. Huh?

The rules are simple: eat nothing, except for water and salt soup.

But wait, there is added torture ... You get to go through all the motions of eating -- putting the food on your plate, cutting it, putting it on your fork, holding it up to your lips. You just don't get to eat it.

Apparently the diet was made popular by a Dolce & Gabbana campaign, which featured Madonna and other celebrities holding food up to their mouths, but not eating it.
