Years ago I've read studies that show that both very
low calorie and very low carb diets reduce T3 output.

In most cases, this is nothing to be concerned about.

"Other things equal, lower levels of dietary carbohydrate mean lower
levels of blood sugar. The simplest and most plausible explanation for
the lower levels of T3 that accompany low-carb diets is that the
amount of T3 required to perform all of its functions is now less."

Which also suggests that "treating to the number" is the wrong thing
to do. Doctors should treat to the patient, and then only if there
are obvious physical symptoms.

Decades of eating the Standard American Diet can play havoc with our
metabolisms. Transitioning to a low carb (or even a calory restricted
diet, as you mentioned above) way of eating requires less T3, so the
body adjusts.

The person who asked about T3 levels and low-carb diets should
elaborate further on why he's inquiring about this subject.
