Type 3 Diabetes – The What and How

 In Asheville, Durango, Farmington, Greenville, Weight Loss

Many people currently believe that we must eat a fairly high load of carbohydrates in order for our brain to function optimally.  This is actually not a true statement.  Did you know that the one macronutrient we actually do not need to eat to survive 

The brain must have glucose for energy, and thus we must have carbohydrates in order for our brain to function.  This is not a true statement.  Studies have shown that the brain can utilize ketones produced on a low carb diet and create the glucose it needs from protein or fat. (1) There has also been research that shows that excessive carbohydrate consumption can actually damage the brain. 

Alzeimhers has been dubbed the type 3 diabetes because of the damage done to the brain by too many carbs. (2)  Blood sugar spikes, even in the normal range, can cause brain shrinkage.  In  a study published in the journal Neurology, it showed elevated hemoglobin A1C (a test that shows average blood sugar levels over a period of 3-4 months) correlated with brain atrophy.  (3)  So basically the more carbs and sugar we eat, the smaller our brain gets.  

High A1C results also affect the brain in the form of depression.  There is now documented evidence showing a direct correlation between hemoglobin A1C and depressive symptoms. (2).  Even in cases of insulin resistance where the blood sugar levels aren’t high, but the pancreas is working overtime to deal with the extra glucose in the blood causes problems with cognitive impairment. (2)

Brain shrinking, alzeimhers, depression, brain fog ; sounds like a bad place for your brain to be,  but the fact is the percentage of people afflicted with these symptoms is on a huge upward trend.   Health authorities project 115 million new cases of alzeimhers in just the next 40 years.  The good news is that a diet that includes minimal carbs and generous amounts of healthy fat, like the PHD program, can prevent and in many cases reverse the damage done to the body.
