master cleanse
n.— «When Teron Beal, a songwriter and aspiring actor in Manhattan, was looking to drop weight quickly for a photo shoot, he didn’t double up on gym visits, gulp metabolic boosting pills or limit his diet to leafy greens and lean protein. Instead, he took a more drastic approach: he tried the “master cleanse,” a fast that requires subsisting for 10 or more days solely on an elixir of fresh-squeezed lemon juice, cayenne pepper, maple syrup and water.» —“I Heard It Through the Diet Grapevine” by Lola Ogunnaike New York Times Dec. 10, 2006.
