It is very difficult to find peer review studies on thyroid function and the effects of a low carbohydrate diet. I've found a few short term studies, but nothing long term. It would be nice to have longer term studies on VLC, but there's just not a lot of people going to be willing to follow such a diet for a matter of years in a study. So if anyone is aware of any studies that might be relevant, please do provide links in comments. What I'm particularly interested in is the second half of the first year - e.g. months 7-12 - and beyond. Because anecdotally, this is the time frame when hypothyroids seem to react rather poorly to a VLC diet. Far more material is available on health and nutrition related sites. While I prefer not to rely on such sources, I think the information available from reasonably reliable sources demonstrate that carbohydrate restriction reduces T3, reduces T4-to-T3 conversion and increases reverse T3 (rT3). The latter happens with all diets but the T4-to-T3 conversion differences I've seen reported are reductions in the 25-35% range with VLC diets.
