Thyroid and Low-Carb: What Do Thyroid Hormones Do?

There's much too-ing and fro-ing over thyroid hormones and low-carb diets on the interwebs, in the paleo and now endurance communities, as low-carb or ketogenic diets have become popular.

Typical was this post by Anthony Colpo from a few years ago: "Is a Low Carb Diet Diet Bad For Your Thyroid?"

"Over the years, an abundance of research has gathered to indicate that, for those who wish to maintain optimal thyroid function, very low-carbohydrate diets aren’t a wise idea."

He then goes through a bunch of studies which all, pretty much, detail that thyroid hormones go down on a low-carb diet.
