There are more nerves in the gut than the brain.

Do You Know You Have a Second Brain?

Overview
There are more nerve cells in the enteric nervous system than in the central nervous system. That's right, there are more nerve cells in your digestive system than in your brain and they are just as busy and important. Further, other than consciousness, the enteric nervous system conducts almost all of the same complex command and control functions as the brain. That's why it's called the second brain.
From the moment you put something in your mouth, and it signals to activate the digestive system, until the food bolus enters the colon, and the bioreactor shuts down, it is at most 6 hours later. Therefore, the enteric nervous system is in full processing mode, doing everything it does for 6 hours after putting any food in your mouth. That's right, even one mouthful activates and requires the full processing and operation of the enteric nervous system for the full 6 hours.
Eating before sleeping has the same effect on the second brain as drinking a caffeinated beverage before bed has on the brain. If you eat a snack before bed at 10 p.m., your second brain's nerve cells don't get to start their Rest, Repair, and Recovery, or "sleep," until 6 hours later at 4 a.m. If you eat again at 8 a.m., your second brain only gets four hours of sleep. So how good do you think you'd feel and how healthy would you be only getting four hours sleep every night?
As the adverse effects of lack of sleep, overwork, and toxins accumulate, gastrointestinal motility generally slows down, further damaging the bioreactor and causing dysbiosis. The additional bioreactor damage and dysbiosis contribute to metabolic syndrome, obesity, and metabolic disease. Over the last few decades, we have steadily reduced the sleep (by late eating), increased the workload (by snacking), and increased the exposure to toxins (by factory food) of the enteric nervous system, bioreactor, and microbiome. It's a small wonder we have an epidemic of bioreactor dysfunction and dysbiosis leading to a metabolic syndrome, obesity, and metabolic disease crisis.
Actionable Knowledge
  • There are more nerve cells in the enteric nervous system than in the central nervous system. Further, other than consciousness, the enteric nervous system conducts almost all of the same complex command and control functions as the brain. For example, the enteric nervous system senses the position of the food bolus based on the extension or pressure on the wall of the bioreactor. Then, the enteric neuro networks issue the correct location, extent, and timing of the muscle contraction through the peripheral system to squeeze the bolus forward. The electromechanics of food movement through the bioreactor works best with a large, concentrated bolus, preferably two or three times daily, associated with meals, rather than eating constantly by snacking.
  • Virtually all living cells thrive and survive under the 5Rs: Response, Rest, Repair, Recovery, and Repeat. Nerve cells are no different, wherever they appear in the body (although only for nerve cells, Repair is debatable). There is a reason eight hours of quality sleep is unquestionably critical to brain health, and therefore the rest of the body. What we call sleep is simply the time it takes for the nerve cells of the brain to complete the three middle steps: Rest, Repair, and Recovery of their 5Rs cycle.
  • Yet, if you eat a snack before bed at 10 p.m., your second brain's nerve cells don't get to start their Rest, Repair, and Recovery, or "sleep," until 6 hours later at 4 a.m. If you eat again at 8 a.m., your second brain only gets four hours of sleep. So how good do you think you'd feel and how healthy would you be only getting four hours sleep every night?
  • Over the last few decades, we have steadily reduced sleep (by late eating), increased the workload (by snacking), and increased exposure to toxins (by factory food) in the enteric nervous system and bioreactor. It's a small wonder we have an epidemic of bioreactor dysfunction and dysbiosis leading to a metabolic syndrome, obesity, and metabolic disease crisis.

Gut dysfunction causes the body to attack itself.
Systemic inflammation, the root cause of many diseases, is the body attacking its own cells. A major cause is a failing gut membrane that allows microbes out of the gut, triggering an immune response. Once the immune system identifies one of your cells as a threat, it may attack it for the remainder of your life.

The liver removes the bad stuff, and so much more.
A Presidential Candidate's advisor famously said “It's the Economy... Stupid.” Yeah, it's the same with the liver. Alcohol and complex sugars cause liver cells to be replaced by fat cells, undermining regulation of the body's biochemistry. As this worsens, organs are damaged, metabolic disease begins, and you feel lousy making you sedentary.
