The biological principle of parallel pathways, where the brain and body act in concert, is fundamental to biological organization.

“So again, and again, we see this in biology and in neuroscience that your brain and your body are acting in concert. They're acting together through mechanisms that either are independent, so separately in the brain and separately in the body, but directed towards a common goal, or through communication between brain and body, and almost always that communication is going to be bidirectional, body to brain and brain to body. So I think these results are really interesting and really important for sake of weight loss, for sake of appetite suppression, and just generally for the way that they illustrate this very important theme of the way that we are constructed at a biological level which is parallel pathways.”
