You realize you're born endo right?  Forgive me for being so out-of-touch with whatever fat-logic-lingo these tubs are using this week, but I haven't heard "endo" yet. Is it similar to endothermic? Just endo, meaning "from within" doesn't sound applicable, except that they kill themselves from within.  An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat.  Have they seriously slipped so far from reality that they believe their body absorbs energy from their surroundings, as opposed to getting it from the Big Gulps and quadruple-bypass cheeseburgers?
