What Fasting Does To Your Brain

This is something that I figured in my own life noted in the workplace (Walmart)
where I am busy working 10,000 LBS of pallets a night.
(The LBS are labeled on the pallets) If I eat a lot of food before I go to work or a
big dinner I get sluggish. Also if I get hungry and shaky it goes away in time.
I view it as like a detox but really it's your body burning fat for fuel. 
It's a good thing vs heading toward Diabetes by eating and eating more than 
you can burn. But I also know it's my brain changing for the better to adapt 
to my body's environment.

There is real research pointing to why that is. And points to a light of how we are 
and where we are going. Diabetes popping up it's head more than it should.
Ever thought why? Are we eating too much too often?

Well the research is pointing that way! *But I have to note if you are Diabetic you 
do need to eat small but often being you need to keep yourself in check with the
blood / sugar! It helps to eat better and in that helps you in being less dependent
on the insulin.

It's not about why "Big Pharma" won't study it. It's just they are way behind.
Food has changed from the past years and has gotten bigger and bigger as many
fast food places have been pushing for better sales from poor consumers.
They are trying to be healthy but it's the confine of low payed consumers running 
things. Healthy tends to cost too much!

But also to that there is a big push by Doctors in medicating people getting the 
Pharmaceutical money coming. Yes I do see that people are over medicated. 
As in elderly people being on three types of blood pressure medicines etc. 
And about the medicines for ADD, ADHD, they might not need them.
It might be boredom in the classroom smarter kids surrounded by stupidly they would be 
labeled ADD, ADHD. I'm not making fun of the stupid but facts are facts! Think about it!
The kids are trying to get from point A to point B with people wanting to stay at point A.

~~~~~Neuroscientist Shows What Fasting Does To Your Brain & 
Why Big Pharma Won’t Study It
Fasting is a challenge to your brain, and your brain responds to that challenge by adapting
stress response pathways which help your brain cope with stress and risk for disease. 
The same changes that occur in the brain during fasting mimic the changes that occur 
with regular exercise. They both increase the production of protein in the brain 
(neurotrophic factors), which in turn promotes the growth of neurons, the connection 
between neurons, and the strength of synapses.

“Challenges to your brain, whether it’s intermittent fasting [or] vigorous exercise 
is cognitive challenges. When this happens neuro-circuits are activated, levels 
of neurotrophic factors increase, that promotes the growth of neurons [and] 
the formation and strengthening of synapses. . . .” 

Fasting can also stimulate the production of new nerve cells from stem cells in the 
hippocampus. He also mentions ketones (an energy source for neurons), and how 
fasting stimulates the production of ketones and that it may also increase the number 
of mitochondria in neurons. Fasting also increases the number of mitochondria in nerve 
cells; this comes as a result of the neurons adapting to the stress of fasting 
(by producing more mitochondria).

By increasing the number of mitochondria in the neurons, the ability for nerons to form 
and maintain the connections between each other also increases, thereby improving 
learning and memory ability.

“Intermittent fasting enhances the ability of nerve cells to repair DNA.” 
He also goes into the evolutionary aspect of this theory – how our ancestors adapted 
and were built for going long periods of time without food.

A study published in the June 5 issue of Cell Stem Cell by researchers from the 
University of Southern California showed that cycles of prolonged fasting protect 
against immune system damage and, moreover, induce immune system regeneration. 
They concluded that fasting shifts stem cells from a dormant state to a state of 
self-renewal. It triggers stem cell based regeneration of an organ or system.

Human clinical trials were conducted using patients who were receiving chemotherapy. 
For long periods of time, patients did not eat, which significantly lowered their white 
blood cell counts. In mice, fasting cycles “flipped a regenerative switch, changing the 
signalling pathways for hematopoietic stem cells, which are responsible for the 
generation of blood and immune systems.”

This means that fasting kills off old and damaged immune cells, and when the body 
rebounds it uses stem cells to create brand new, completely healthy cells.

“We could not predict that prolonged fasting would have such a remarkable 
effect in promoting stem cell-based regeneration of the heatopoietic system. 
When you starve, the system tries to save energy, and one of the things it can do 
to save energy is to recycle a lot of the immune cells that are not needed, 
especially those that may be damaged.  What we started noticing in both our 
human work and animal work is that the white blood cell count goes down with 
prolonged fasting. Then when you re-feed, the blood cells come back. ” 

Valter Longo, corresponding author A scientific review of multiple scientific studies 
regarding fasting was published in The American Journal of Clinical Nutrition in 2007. 
It examined a multitude of both human and animal studies and determined that fasting is 
an effective way to reduce the risk of cardiovascular disease and cancer. 
It also showed significant potential in treating diabetes.
