The Importance of Sleep

Today, we are going to cut deeper into the leptin story. We need to look at the leptin receptor because its biology will explain why studying macronutients at a dietary level just becomes a confusing mess with seemingly multiple paradoxes. I recently commented on this in Paul Jaminet's blog on August 24th 2011. The comment was very detailed but not written well so I am going to lay out the reasoning in the next few blogs. As most of you know leptin is the lynchpin in my Quilt and sits at position two. Many people might not realize how important it is for health, in sickness, and for optimal endocrine function. It is the dominant factor in obesity and this series is out to show you why this is the case based upon the data coming out of some labs who specialize in this neurobiology. This series is going to be laser like biochemistry on a 30 foot level. When we talk about this type of lab science it is very easy to lose perspective of the larger story I am trying to unveil to you. I have previously called leptin the master hormone of the brain. Remember that the brain has two ways to control things, one is direct neural wiring and the second is the control over the hormonal secretions body wide. Given these two factors, I think I may have under called it, honestly. This hormone signals the entire body's nutritional status, metabolic status, and endocrine status to the brain at all times. The brain in turn uses leptin to regulate total glycemic control, energy balance, and all neuroendocrine function in all systems in humans. This means that energy regulation is centrally controlled by our neuroendocrine system. The brain uses this hormone as an afferent and efferent signaling hormone to know precisely what is going on in our 20 trillion cells body wide. The brain does not have direct wiring to all 20 million cells because of space limitations of our cranium and our mother's vaginas. So it uses hormones and cytokines to extend its power and reach to send signals to those 20 trillion cells.
