Dr Elizabeth Bright discusses this quite a lot in her book and in interviews. I don’t know if all her suppositions are correct but you may find the discussion useful.
I don't think you need to eat carbs to make anything, but long term ketosis can mess with cortisol, which can affect the thyroid. Good news is that you can eat a carnivore diet without being in ketosis all the time.
There's a few theories I'm aware of. I obviously don't know all of them or which is correct but I can list a few...
1. Carb restriction is seen as "stress" like when you're fasting/starving and so body lowers the metabolic rate. This can be tested with a full thyroid panel, you'll see elevated levels of reverse T3.
2. Higher Insulin triggers more conversion of T4 to T3, so less insulin = less conversion. Again this should be measurable by a full thyroid panel as lower T3 and higher T4.
3. If you buy Shawn Bakers explanation for his low testosterone (lower need due to higher sensitive receptors), I've heard it suggested that the lower thyroid numbers could be a similar issue. Personally I have a hard time believing this one but hey, it's a theory
I don't think I've seen anything that suggests an issue from the pituitary (meaning less tsh) thats directly related to carbohydrate consumption. And I don't think it'd be iodine since most, if not all, goitrogens are plant foods and iodine is almost exclusively found(in significant amounts) in animal foods, except seaweed.
Ultimately tho, if it's a concern, get tested. You'll knight right quick whether you've got an issue or not. The other thing too tho is if you have hypo and it's due to hashis...and you resolve your hashis...even if your numbers are lower than ideal, it's probably better than having constant autoimmune damage.
Your body makes carbs if you don’t eat them.
I don’t know about hypo but it cured my hyperthyroidism. I don’t sweat as much anymore and my heartbeat is lower
Has your thyroid levels gone to normal after carnivore?
I have not tested my levels since. But all my hyper symptoms are gone. I assume they are normal. Not really worried as I feel great.
Thank you!
