The hCG Diet. This diet is insane, and scarily it's the most popular diet search on AOL these days. In addition to limiting yourself to about 500 calories a day, you also inject yourself with hCG—the same hormone that's (a) found in human placentas and (b) that lots of Major League Baseball players got in trouble for using. Eek. People who do this can lose 1 to 3 pounds a day. Which can't be healthy. [AOL]
