all right guys i’m chipping  away at all your questions  

on the youtube channel and facebook  and this next video is based on a  

kind of a comment not a question it’s basically  a disagreement someone said dr berg you don’t  

know what you’re talking about because our bodies  were meant to run on glucose especially the brain  

and i wanted to do a video on this topic  because i think it’s important it is true  

that a certain part of your body can only run on  glucose okay but a greater portion of your body  

can also run on ketones and fatty acids i  mean if you just think about this logically  

most people in america especially are overweight  they’re carrying a lot of fat around their body  

now the question is what is the purpose of fat  is it just an insulator is it just to protect  

you against the cold or act as a cushion if you  fall down or could it be that that fat that you  

have is a fuel storage to survive between meals  our bodies only store roughly about 1700 calories  

of stored sugar but a thin person has about  a hundred thousand calories of stored fat  

so based on logics our bodies were meant to run on  fat more than glucose but it is true that certain  

parts of our body only can live on glucose and  that would be the red blood cells your liver  

yeah your liver actually cannot run on ketones  30 of your brain especially certain parts of your  

pituitary and hypothalamus need glucose certain  parts of the kidney can only run on glucose and  

the lens of the eye needs glucose but here’s the  key thing there’s something called gluconeogenesis  

that is a condition where your body is actually  making glucose from non-carbohydrate sources  

like fat and ketones that’s right if  your body needs glucose it can make it  

from ketones so you do not need from your diet any  glucose to survive at all in fact when you start  

putting your body into a state of ketosis and you  start feeding the brain ketones and your heart  

ketones you see all sorts of amazing things that  occur improvements in focus memory ability to  

learn and your overall mood and just because  i’m on the topic of brain physiology there’s  

a structure in the brain called a hippocampus  and that structure if damaged leads to dementia  

and alzheimer’s and your hippocampus thrives it  improves when you feed it ketones and it worsens  

when you feed it glucose so both the hippocampus  and the prefrontal cortex thrives on ketones and  

this is exactly why when you get into ketosis your  focus is better your memory gets better and your  

concentration improves and so if you’re new to  my channel and this is all new to you definitely  

watch some videos down below so you can experience  the massive benefits before you go if you have a  

question about a product or you’re new to keto  and you want to know how to begin keto or you’re  

on keto and you need a debug because it’s not  going as smooth i have a keto consultant standing
