[QUOTE="mcs, post: 166747, member: 12"] I am dealing with a similar dilemma being on a LCHF diet for some time now, although I haven't been able to ascertain any difference in markers since my carb intake has remained static @ ~ 75g daily. Your numbers are characteristic of Subclinical Hypothyroidism (see chart below) in which TSH is mildly elevated and FT3/FT4 are normal. To get a better overall clinical picture, you also need to check antibodies (TgAb and TPO). Some questions: 1) Do you have thyroid labs before you started going LC and CR? 2) Are you on TRT? 3) What do your avg macros look like? 4) What are your symptoms, if any? I didn't see you post that, just that you feel your metabolism slows down. It's long been known that low carb diet can definitely downregulate T3 (as well as testosterone). And LC + CR is like a double whammy! Studies are mixed as to whether such restriction directly affects TSH which is a pituitary hormone.[ATTACH=full]8867[/ATTACH] If what you say is true - that your TSH is still mildly elevated (high normal) + your frees are normal when you're not restricting cals or doing LC - then it seems such baseline levels are dead ringers for classic subclinical hypothyroidism and you should be on thyroid replacement. I would start with 1 grain NDT (not Armour; it has too many crappy fillers that can cause reactions and absorption problems) and monitor rT3 levels before jumping on the T3 monotherapy bandwagon as others have suggested. If no problems, the titrate slowly 1/4 to 1/2 grain every 2-4 weeks. Just because rT3 is elevated doesn't always equate to exogenous T3 as being the panacea. In fact, Barbara Lougheed's Tired Thyroid blog suggests a contrarian opinion: that too much T3 will be just as much a problem in shunting to rT3 as too much T4. It's all very individualized and the science is hazy when it comes to how valid rT3 is in the first place. We really don't know enough to suggest any real clinical significance, not to mention actionable protocols. [/QUOTE]
