"Within 24 hours of curtailing food intake, enzymes stop entering the stomach and travel instead into the intestines and into the bloodstream, where they circulate and gobble up all sorts of waste matter, including dead and damaged cells, unwelcome microbes, metabolic wastes, and pollutants." [cite] Could this possibly be true? I know that eventually the body will start metabolizing itself, but is the process selective in its initial stages to only metabolize "waste matter" and not healthy tissue?

I’m looking for ways to increase my appetite. I’ve always had a fast metabolism, and now that I run 30+ miles a week, I know I’m not consistently getting the calories I need. Developing an appetite would certainly help me get the necessary intake. In addition to appetite boosters, I’d also be interested in (vegetarian) foods that are particularly calorie / nutrient rich so I can get more out of each meal. Protein shakes help, but I wouldn't mind actually wanting food more often.

Reading, watching TV, and surfing the web. All three of these involve equal levels of inactivity -- so why is it that I only think of TV watchers and computer users as "at risk" for sedentary-lifestyle health issues, but not avid readers? Why is it that I feel like I'm burning more calories when I'm curled up with a book than when I'm clicking with my mouse?
