hey I’m back today we’re going to talk about internment of fasting lower carbohydrates and your thyroid many times I’ll hear from someone that it’s dangerous for your thyroid to do low carbohydrates or fasting that’s what destroys the thyroid okay that is absolutely not true let me first kind of give you the basics you have this thing called the pituitary it’s a small gland in your brain by the size of a pea and it sends a message down to the thyroid it controls the thyroid thyroid at the base of the neck right here it’s about two and a half inches wide it comes from the Latin word which means shield because it looks like a shield so this gland that’s triggering the main thyroid hormone is being controlled by the pituitary through something called the thyroid stimulating hormone pretty much describes what it is right so then the thyroid releases its main hormone called t4 the four represents the number of iodine molecules so t4 is an inactive thyroid hormone it has to be activated to make it work and eighty percent of the activation happens to the liver and 20% happens to your kidney so what happens when it gets activated through certain enzymes it strips off an iodine and it becomes t3 okay so t3 is the active form of the thyroid hormone so t3 does its job and it does has everything to do with metabolism and speeding things up and making things work through pretty much all the cells so when it does its job it sends a signal back up to the pituitary complying with this order completing the action and then this can turn off so we have this whole feedback system that’s dependent on a lot of different things the environment food etc now it is true there are certain things that will influence these hormones like a low carbohydrate diet and fasting can cause a low normal t3 okay that’s active form it’s not necessarily abnormal but it could be low normal ok still within the range okay why would it be low normal simply because T 3 is constant getting feedback from the environment if you eat a lot of food it has to speed up to keep up with the metabolism if you eat less food or less frequent food it can slow down what you’re gonna find is the thyroid stimulating hormone is going to be normal and this is how they diagnose a hypothyroid problem okay so it’s going to be normal and t4 is probably gonna be normal too you may just see a slight dip in t3 and that is because you’re not consuming the frequent meals and the quantities of sugar that you did before and this is totally okay because your body just doesn’t need to produce the quantities of t3 you may also see another thing okay higher reverse t3 now what is that what what happens is if the body doesn’t necessarily need is much t3 it can put it in an inactive form okay it’s called reverse t3 so t3 is kind of similar to t4 it’s just an inactive form of t3 now why would this be higher because the body is just adapting to the environment it doesn’t need as much t3 so it puts it into an inactive form because if it did keep going and you produce more and more t3 when you didn’t need it you can end up with a hyperthyroidism okay if you didn’t have this and it kept going and you produce too much t3 you can end up with a hyper state the hyper thyroid state now what happens when you go on a little calorie diet okay and you don’t change your carbohydrates you have higher months of carbohydrates like most calorie diets do or even go through stress or infection you could actually have an alteration in the thyroid stimulating hormone right here and you can have low t3 and even low t4 but if you’re doing this if you’re doing in a minute fasting and you’re losing weight and you’re on a low carbohydrate diet and you’re having energy and you’re feeling good and you’re not hungry and your hair is not falling out okay and you find out that you have a low normal but you have a normal thyroid stimulating hormone just realize that this is this is a totally okay situation it’s not gonna be a problem so one more point I want to bring up about iodine okay this is an iodine deficiency can very easily create a hypothyroid state but if you’re taking a high quality seek help that will protect the thyroid iodine is very very good for women and then it helps balance the estrogen out also good for men their prostate so it’s a very vital trace mineral alright guys thanks for listening talk to you later so I hope you’re coming to the keto health summit coming up in October so I want to quickly comment on what we’re gonna do that’s different from other conventions okay the problem with these other conventions is they give you information over a load okay it’s so much data that you’re basically swimming in a sea of information we’re going to do things very differently we’re only going to cover the most important things that make a huge difference now there are three very powerful strategies that we’re going to be talking about at the summit that you will not find and any of my youtube videos number one is on memory I’m going to be showing you something very cool to dramatically increase your memory and concentration that’s going to blow you away and number two I’m going to show you how to increase your stress tolerance so you are completely calm all the time alright and number three and most importantly if you have a slow metabolism if you’ve died it for a long time and everything is kind of just really slow I’m going to show you how to get complete control over your metabolism so you can literally turn up the dial as high as you want and control as much weight as you want to lose and these three things are just a tiny bit of what you’re going to learn in the summit so click the link below get signed up and I will see you in October
