Circadian Cycle

Cold Thermogenesis 4: The Holy Trinity

I just want to thank Sean Croxton for asking me to present at Paleo Summit today. The ideas discussed began with a podcast I did with Jimmy Moore, #474. Before I begin here today, I strongly suggest you listen to the Jimmy Moore podcast I did in May of 2011 as a primer for this blog post. It’s going to be a long one, so open a glass of wine as the sun sets tonight. However, I think you need to hear it all tonight since I have your attention from the Paleo Summit. I have planned for this day for some time. I am humbled to share this with you all. It was hard for me to write. If any of you remember when I first gave my initial thoughts on leptin publicly, it was on a podcast I did with Jimmy Moore in May 2011. I discussed the things that transformed my thinking back then. Most of the time I spent with Jimmy, we talked about leptin. In the beginning of the podcast, I mentioned a person who saw me injure myself as I stood up to give a lecture, and told me she knew precisely why I hurt my knee. At the time, I thought I had a good handle on these modern medicine principles she mentioned so I was a skeptical of her thoughts. She told me when I got home she was going to send me a few papers and a book to read. The book was called “The Monk Who Sold his Ferrari.” She was emphatic that I read the book before the papers. Then, she told me to read six specific papers in the order they were numbered and then reflect on what I had just read.

Cold Thermogenesis 3

Evolutionary strategy is based upon finding an environmental niche and exploiting it. Evolution is based upon change and the natural adaptations to it. Today, we are going to explore how some environmental triggers might open a “biochemical trap door.” Why is circadian biology critical? For evolution to work, a cell first must adapt to its environment. So the first thing any living cell would see in an earth day is a period of day and night. It also has to find food to make energy (ATP). In addition, it has to control its own cellular division. The epic battle for the cell is the circadian cycle has to “yoke” the metabolic cycle to its growth cycle. Most people know that the suprachiasmatic nucleus (SCN), is the circadian pacemaker that monitors this dance between darkness and light and the seasonal cold and hot temperatures in our environment. Evolution apparently agreed with this assessment, because we now know it to be true. What most people do not know is how leptin plays a massive role in regulating it. Research has revealed that leptin can induce expression of a neuropeptide gene called vasoactive intestinal peptide (VIP) through the VIP cytokine response element. VIP actually is what sets the circadian pacemaker to light. Leptin yokes metabolism and sleep to the light and dark cycle. When temperature becomes the dominant environmental trigger and not light cycles, leptin induces endothelial nitric oxide synthetase (eNOS), that shuts down the photic effects of VIP on the SCN. This means that leptin forces the SCN not to be able to use light any longer to yoke circadian cycles! Once temperature begins to yoke the circadian rhythms, some very special things happen to our biochemistry that normally does not occur in other environments. These are ancient epigenetic programs that are hardwired into the DNA of every descendant of a eutherian mammal. We are descended from these animals.

Cold Thermogensis 2

Now that you understand that I believe cold environments were how life first evolved, what implications does this hold for all life and humans today? I think with this thought experiment we need to begin to talk about another aspect of evolution to fully conceptualize how cold works for biology. Let’s talk about sleep for 4 short minutes. First, I want you to watch this video before you proceed. Recently, one of my readers pointed out he was confused by Dr. Gamble when she said the normal pattern of sleep in a natural environment had two cycles. He wanted to know why her version and my version for sleep as written in my post “Rx for the Leptin Rx” were not congruent. It was a great question that really opens the discussion to the idea of evolutionary mismatches. These mismatches occur in many modern systems of biology, and they are actually increasing in frequency and severity as time elapses. The reason is quite simple. Evolution is constantly getting faster as time goes on, relative to the current state of our genome. This is really how the “cellular theory of relativity” is currently affecting our own genome today. The speed of evolutionary change has far out stripped the ability of our paleolithic genes to catch up. This mismatch causes major problems for modern humans. When they further exacerbate the system with choices not congruent with our biology, the results are magnified in disease incidence and prevalence. She also mentioned in passing, early in her talk, that people who went deep into the ground have been found to be “very productive” while in a cold dark environment. She did not expand on this concept at all, but I would strongly suggest you remember this as the cold thermogenesis series progresses on. There is a deep biologic reason this occurs. As we use this pathway, lots of things improve that we do not expect.

The Cold Thermogenesis Protocol

The Cold Thermogenesis Protocol should be added gradually to the Leptin Rx rest protocol. This blog post is additive to the Leptin Rx, and is an evolution extension of it for those who need it. I hope you all realize that not everyone will need it. Some will need it because they have special needs that they face. This blog is designed for those who have been previously left out of the reset protocol. Those people are gastric bypass patients, HCG users, those on exogenous steroids, chronic pain patients, and those with T2D and metabolic syndrome, as a few examples. Prolonged and controlled local peripheral skin cooling can induce selective “damage,” and increased hypothalamic signaling by forcing adipocyte apoptosis and subsequent loss of subcutaneous fat without damaging the overlying skin or the underlying muscle layers. This means that acute cold cause rapid leptin sensitivity! It means that fat is forced to liberate leptin from fat cells to slowly lower its serum levels as long as the cold stimulus is applied safely. This is new scientific information that was first carried out in pigs in 2008, and subsequently tested in humans and found to be quite effective for fat removal in certain selected areas of the body.

Rewiring The Leptin Rx Reset

Evolutionary strategy is based upon finding an environmental niche and exploiting it. Evolution is based upon change and the natural adaptations to it. Today, we are going to explore how some environmental triggers might open a “biochemical trap door” that will allow me to add a new recommendation for you to consider adding to the Leptin Rx reset protocol for those who are LR. I am beginning a series on circadian biology to show you how this all ties in together. Today, I will give you a very cursory review of why circadian biology, leptin, and environment are critical to using the Quilt to obtain your Optimal life. Why is circadian biology critical to humans? For evolution to work Optimally, a cell first must adapt to its environment. The first situation any living cell would be subjected to in an earth day is a period of day and night. Over time it would also be subject to the seasons in our environment because of the earth’s revolution, tilt, and angulations of the sun. As time continued on, further life would have been subjected to solar variations and would have had to account for it. It also has to find food to make energy (ATP) to survive, and it also has to control its own cellular division. The epic battle for the cell is to have the regularly expected circadian cycles found in our environment and ”yoke” those signals to its metabolic cycle and to its growth cycle. Most people know that the suprachiasmatic nucleus (SCN) in the brain is where the circadian pacemaker lies in humans. It monitors this dance between darkness and light, and the seasonal cold and hot temperatures in our environment to help control and monitor our own growth and development. Evolution apparently agreed to use these signals in all living things because this is what it uses for all life on earth today. What most people do not know is how leptin plays a massive role in regulating it. Many people and physicians think it plays a small role. Recent research has revealed that leptin can induce expression of a neuropeptide called vasoactive intestinal peptide (VIP) through the VIP cytokine response element. This is an epigenetic modification from our environment directly signaling the master hormone in our body. So what does VIP actually do?

Cortisol Response

Cortisol is a glucocorticoid hormone. It is the most important one in humans, produced by the adrenal cortex and participates in the body's homeostasis and stress responses. Cortisol concentrations also follow a circadian rhythm. It is a more complex rhythm than the human melatonin rhythm. Unlike the melatonin rhythm, human cortisol rhythms do not seem to be totally associated with day and night per se, but seem to be more closely tied to the "transition periods" from dark to light and to a lesser extent, from light to dark. Transitioning light levels play a tremendous role in cortisol rhythms in humans. In addition to its circadian rhythm exhibiting a predictable peak in the morning, cortisol levels typically elevate sharply in the morning, 30 minutes to an hour after awakening. The glucocorticoid levels synthesized by the adrenal gland across the 24 hour day appear to be under the control of two distinct systems, one governed by the hypothalamic-pituitary-adrenal (HPA) axis, and one controlled by the autonomic nervous system through the adrenal medulla. Evidence supports that cortisol production can be uncoupled from the HPA axis controller of its release (ACTH). Night time light stimulates the suprachiasmatic nucleus (SCN) and this sends a neural signal to the autonomic systems to increase cortisol production from the adrenal gland, but not the brain. This is not coupled to pulsatile ACTH release in the pituitary, and has separate neural pathways. Studies have shown that exposure to high levels of polychromatic (white) light (80lux at the cornea) in the morning, but not in the evening, could increase cortisol levels in humans. It appears the intensity of light is critical to the real effect on cortisol levels. Studies have also shown that morning light can increase heart rate, suggesting an impact of light on the autonomic nervous system that modulates cortisol release from the adrenal gland. More recent studies have shown bright light to dramatically reduces cortisol levels in humans.

So You Completed The Leptin Rx? What’s Next?

Once you have added the Leptin Rx to your paleo/primal template and you have successfully experienced all the "small wins" that I mentioned in the Leptin FAQ's blog, what should you do next? If you recall reading the blog on how the leptin Rx works, it basically is a plan to make your gastrointestinal tract perform visceral exercises that it is not accustomed to performing, in order to cause neuroplastic changes in your hypothalamus' arcuate nucleus. It uses the vagus nerve as the "stimulator" to send these new messages to the brain. After a period of time, the inflammation will slowly dissipate at the median eminence, and these afferent signals will force expression of certain genes that have been repressed since we were in utero. These genes and pathways are hardwired into our DNA at conception, and used until the child is 12-24 months old. After this time, they are not expressed any longer, because transgenerational epigenetics favors instead the use of the leptin receptor from an evolutionary perspective. This occurs because the leptin receptor in the arcuate nucleus is far more sensitive and accurate in accounting for electrons from food than was using older circadian and ultradian cycles that we used in uteri during morphogenesis. The human brain learns "what neural circuits" to use by repetitive firing. We have a saying in brain surgery, nerves that fire together wire together. This is the basis of the theory of Hebbian learning. These exercises I told you about in the Leptin Rx signal hypothalamic neurons to adapt to these visceral responses to food in a new way, to sensitize the leptin receptor in order to account for electrons from food in precisely how it was designed to do by evolution. In essence, we are altering the genetic expression of the genes in our arcuate nucleus. I describe it to my patients as "performing brain surgery on them without using a blade." The visceral responses to the Leptin Rx are transcribed by the vagus nerve, and this information is sent to the brain. This message is dramatically different than the one the patient is used to giving the leptin receptor, and the new message induces changes to the neuropeptides in the brainstem. After some time, (6-8 weeks for most) changes will be induced. These can be followed by the clinician or the patient. Those clinical signs are outlined in the Leptin FAQ blog post. In doing this, we force the neurons to see neurochemical signals that radically confuse the leptin receptor and the brain. The brain's response to a signal it does not understand is to revert to an older known pathway or to learn a new way to tackle on old problem. I would suggest you watch How your brain re-learns from 2007 by Dr. VS Ramachandran in a TED talk. He exquisitely explains how this type of learning is stimulated in the brain for phantom limb pain and its treatment. One need not use expensive technology to induce gene expression. It is possible to do without an NIH grant too. It requires some synthesis of thought and experience. When you understand the essence of how the brain works, you just need to design a program and force it upon the brain to decipher what to do. That is the essence of the Leptin Rx reset.

How Does The Leptin Rx Work?

Many people have contacted me about "why" the leptin Rx works and "how" does it work. Many people in the blogosphere have made some claims that much of what is in the leptin Rx is a rehash of the work found in some diet books. Well, today's post is being done to show you the science underneath my recommendations were formulated and made. None of the underlying science I will mention to you about neuroplasticity will be found in any diet book mentioned in any blog post that I know of. Most of you know I am a neurosurgeon, and as such, I was dramatically influenced by two world famous neurosurgeons named Wilder Penfield and David Kline. Dr. Penfield was the first neurosurgeon to use electrodes on the brain to map it prior to surgeries to avoid neurologic damage during tumor removal. Dr. Kline was and still is the pre eminent world expert in peripheral nerve surgery. I happened to train with Dr. Kline in New Orleans, and got turned on to his work, Dr. Penfield's work and the work of Dr. Merzenich in the early 1990's before leptin was even discovered. Dr. Michael Merzenich work on sectioning the median nerve in the hand and seeing how the brain remapped its sensory territory in the cortex via micro-electrodes was brought to my attention by Dr. Kline while I was a resident.
