Just discovered dermadoc, and wanted to give him a shout-out:

Sounds boring, I know, but he's funny, knowledgeable and to the point.

Quote from the "coffee grounds against cellulite?"-post:
"Massaging the cellulite (with coffee, tea, grapes, cream cheese, or chocolate frosting) pushes the fat back into the skin, temporarly improving the appearance. There is no science behind using coffee to treat this normal condition.

Scientific studies have shown, however, that carrying a wet coffee filter filled with grounds into your bathroom will burn more calories because you’ll spend 20 minutes later cleaning up the mess in your shower."
