so sometimes going on a fast has the potential to lower a thyroid hormone

called t3 and that’s the active form of the thyroid hormone t4 is the inactive

version so I’ll explain why that is we have the pituitary up here that

communicates of the thyroid through this hormone called thyroid stimulating

hormone and one of the main ways that hypothyroidism is diagnosed is by

looking at this hormone right here but when you fast for the ketogenic diet and

do it healthily you’re not going to see a change in this hormone right here so

you are not going to have a true hypothyroid condition or problem then

the thyroid releases t4 which is the inactive form of the thyroid hormone to

become activated it has to work through the liver into the kidney but it

converts from t4 to t3 and T is the active form of the thyroid hormone but

there’s something else over here called reverse t3 and the difference between t3

and reverse t3 is that t3 is active in Reverse t3 is an inactive version now

I’m not going to get into the technical part of this but I just simply want to

tell you that what determines the rate and ratio of this conversion to t3 or

reverse t3 is the metabolic need because this has to do with preserving energy

when you do a fast you may see a slight decrease in t3 and many times it’ll

still be within the normal range but you’re going to see an increase in the

reverse t3 your body is simply becoming more efficient with its fuel so the need

for the active thyroid hormone is going to be a little bit less the body will

then put some of that hormone into a little bit of a reserve until you need

it and it’ll be released once you are refeeding and you eat again there’s

several situations where you’ll see higher amounts of reverse t3 when you’re

doing fasting or when you’re recovering from a stroke or

injury or overtraining when you’re exercising or when you’re recovering

from an illness or surgery or when you just have lost a good amount of weight

reverse t3 will go up but one thing I wanna show you is t4 usually represents

90% of all the thyroid hormones t3 will represent about 9% of all the thyroid

hormones and reverse t3 usually represents about 0.9% there is a very

small amount at four months it’s like point one that is designated for

something else because fasting slows the conversion from t4 to t3 so it just

dumps out over here it’s not a disease state

you’re still gonna feel fine you’re still gonna lose weight you’re not gonna

have any of the symptoms but I think it’s important for you know what’s

happening sometimes to certain people when they do a fast as it relates to the

thyroid thanks for watching

hey we’re back with another amazing recipe no grains

no sugar totally keto there’s no suffering on keto absolutely not Karen and
