so I wanted to answer the question is

keto low-carb actually safe for the

thyroid or is it gonna end up ruining

your thyroid and creating damage let’s

take a look at that here we have the

thyroid it’s in the base of the neck

right down here about two and a half

inches wide the thyroid makes t4 it’s

controlled by the pituitary a hormone

called thyroid stimulating hormone so

this basically is what causes the

thyroid to make tea for now t4 is

actually a pre hormone or inactive

hormone it doesn’t really do much it has

to be converted to t3 the 4 and a 3 are

the number of iodine molecules so what

it strips off an iodine molecule becomes

t3 becomes active this happens through

the liver and the kidneys 80% of the

conversion happens to the liver and 20%

happens to the kidney so when you go in

a keto or low carb eating plan it is

actually true that t4 will decrease up

to 40% now that’s pretty scary if you’re

only focusing on this one factor but

we’re gonna take a look at the whole

picture so many people take this out of

context and they end up giving you the

wrong information so here’s the facts

there are no studies out there that show

any negative effects on the thyroid when

you go on a ketogenic plan or a low carb

diet 0 studies in fact and this is

interesting despite this drop by 40%

there is no drop in actual metabolism

and the way that someone is diagnosed

with hypothyroidism which is a slow

thyroid is through thyroid stimulating

hormone but guess what when people do

keto or low carb diets this does not

change so this is 0 also t4 doesn’t

change only t3 and this is with all

types of populations athletes super

athletes overweight people so how do we

explain this well here’s what’s really

happening

t3 is becoming more sensitive I mean

think about insulin when you do a key to

a plan or you’re doing low carb you’re

fixing insulin resistance you are making

insulin more sensitive what does that

mean it means that that hormone is

working more efficiently it’s working

better instead of getting 25 miles a

gallon you’re now getting 40 miles of a

gallon so you’re actually getting better

gas mileage with this t3 becoming more

sensitive I believe what’s really

happening is that high carbohydrate

diets increase the need for a more

thyroid hormone and that’s why it’s

higher and then you go to ketogenic

low-carb diet which I believe really is

a normal way of eating it’s a healthy

way of eating this goes down 40% which

is not abnormal that number is actually

normal on what our bodies were designed

to use so in summary when you do a low

carb keto plan you’re actually improving

the efficiency of the thyroid you’re not

making it worse this is not worse you’re

just not needing so much t3 does that

make sense
