I don't understand the post, but I have a "fast metabolism" according to my team of gastroenterologists trying to figure out what's wrong with me. Normal people apparently don't take a huge dump 8 hours after a colonosopy. Food isn't supposed to be processed that fast, and it's incredibly difficult for me to gain weight just by eating, I couldn't eat that much if I tried. Weight training and lots of supplemental protein is the only way for me.
