let’s talk about the hypothalamus what is  the hypothalamus well it only represents  

one percent of your entire brain but it’s  one of the most active parts of your brain  

it’s half gland and half nervous system it’s half  endocrine system and half autonomic nervous system  

the endocrine system makes actual hormones  as its communication and then the autonomic  

nervous system uses neurotransmitters as  its communication and this includes both the  

flight or fight sympathetic nervous system  and the parasympathetic or rest and digest  

you can kind of look at the autonomic nervous  system as not necessarily an on off switch  

but a dimmer switch because so it turns up  gradually certain functions and turns them  

down like in blood pressure right you just kind  of go up a little bit or come back down and so the  

hypothalamus controls a lot of things urination  appetite temperature stress reproduction fluid  

salt glucose levels sleep cycles metabolism  smell blood pressure thirst growth and sex so  

the hypothalamus really is all about homeostasis  because here you have all these sensors on the  

surface of your body you have sensors in your  blood vessels to measure blood pressure so you  

have these little sensors in your tongue that will  tell the rest of the digestion what’s coming down  

to be able to prepare for that enzymes acids bile  salts things like that you have also sensors in  

your in your cells to monitor how much fluid that  you need inside and outside so there’s a lot of  

this sensory information going into the body and  then it’s causing this gland to make adjustments  

so basically this gland is part of homeostasis  it’s like a thermostat that either increases or  

decreases the function but the overall goal is to  keep things at a constant okay so it’s all about  

balance it’s all about energy balance and when  i’m talking about that balance i’m talking about  

you know your temperature being 98.6 also  there’s certain amounts of electrolytes  

inside and outside the cell your glucose should  be at a certain constant level you should sleep  

for a period of time blood pressure 180 over  60 so the goal of hypothalamus is to respond  

to sensory information that’s coming in from the  environment to make adjustments to the entire body  

and adapt to what’s happening out here for the  goal of creating homeostasis or balance so let’s  

say it’s hot outside right your body’s going to  start sweating to adapt to that temperature so  

we’re not overheated so we can do a cool down like  let’s say for example we’re going to run up a hill  

well we need to quickly increase the blood  pressure to make sure that we have oxygen up to  

our brain because if our blood pressure doesn’t  go up there’s not enough oxygen to run to our  

certain parts of our body and will collapse and so  the hypothalamus is really a mini computer and it  

sends its information down to the pituitary out  to other glands and that’s the endocrine system  

as well as through the autonomic nervous system  now what’s interesting about hypothalamus is that  

you can develop inflammation in the hypothalamus  and that comes from what they call over nutrition  

i like that word over nutrition you have too  much nutrition too many calories i don’t know  

why they’re calling it over nutrition when in fact  those calories are probably too many carbohydrate  

calories that’s kind of a weird name for over  nutrition too many carbohydrates right because  

if you have over nutrition you get obese and  you develop something called metabolic syndrome  

that comes from inflammation  so too many carbohydrates  

will cause the hypothalamus to become inflamed and  then cause you to get metabolic syndrome which is  

high blood pressure a slower metabolism  you get a gut you start retaining fluid  

your glucose starts going up you get sleep apnea  you become a pre-diabetic so you’re going to be  

thirsty all the time right you’re going to urinate  excessively especially five or six times a night  

you’re going to be always hungry you have a  decrease in testosterone which lowers your sex  

drive you lose your growth hormone which is your  fat burning hormone and you may find that your  

metabolic set point is too high so let’s say for  example um you’re trying to lose weight and you  

just cannot get down below 180. your goal is to  get down to 130 but your set point is 180 and your  

body just fights it this is exactly where your  body is going to stay and if you try to get below  

that your body’s going to fight it so your set  point really is all about having this right here  

the metabox syndrome and that it really is high  levels of insulin and what’s really behind that is  

insulin resistance so how do you get rid of this  right here you get rid of inflammation you simply  

stop consuming the excessive amount of  carbohydrates you get on a healthy keto plan  

you do intermittent fasting you start to lose  weight you reverse this and then things start  

becoming back into balance so by getting on the  right diet you can create huge effects not just  

on your endocrine system but the autonomic nervous  system and hypothalamus is simply a combination  

of both of those systems hey before you go  real quick i have a course entitled how to  

bulletproof your immune system it’s a free  course i want you to take it and here’s why  

here’s you here is your environment everyone  is focused on this over here avoiding  

your environment but what about here what about  strengthening your immune system that’s what’s  

missing this course will show you how to  bulletproof yourself and so you can tolerate  

and resist your environment much better by  strengthening your own immune system i put
