It intrigues me that he said he would poop a lot less. Most of the mass in poop is actually dead bacteria living off of the food that you can't process (and whose waste we reabsorb at times). We know from studies that the intestinal flora varies quickly depending on what you eat. I also know that my mood swings depending on what I eat. So his account of mood change (he said he felt very energetic) is very plausible. It looks to me that he reduced the numbers of intestinal bacteria by a dramatic amount with his diet. I wonder what potential side effects (good or bad) this could have. Scientist studying the intestine here? Something to look into I guess. :)
