If you’re a lover of intelligence, then it’s reasonable to assume that you’ve got some high regard for the brain. How many people would argue against the supremacy of one of our favorite and most useful organs? Modern medicine understands the head-brain to be “command central” – the place from which our entire life receives its marching orders. But there’s another kind of intelligence that’s an equally potent metabolic force, and it’s found in the belly. Some call it the “gut-brain,” others proclaim it to be the “brain in the belly.” However you choose to name it, it’s way smarter than you might have ever imagined. And putting this extra brainpower to work can forever change your metabolism, and your life.
