Does paleo lower thyroid function?

Answered on August 19, 2014
Created June 27, 2011 at 4:34 AM

Hi all. I have Hashimoto's and have been dabbling in paleo for a few months and doing it strictly for a few weeks.

As I've been cheating less, I've begun to feel a bit worse in a specific way. I have muscle pain in both arms. I had this before when I was trying to get the thyroid drugs worked out and my sense is that I get this odd muscle pain when the thyroid meds (Levoxyl) are too low or when for some reason I'm not metabolizing the meds properly. I went for quite a while without this pain but it has reappeared with a vengeance over the last couple weeks.

So, is there any reason to think that a paleo low-carb diet lowers T4 or T3? If so, why?

Thanks for your help.

I would check with the thyroid board but if memory serves me the very minimum suggested is 35g and many eat higher (65-75g). I still would not do fruit or starch. If weight's still not budging I would play with lowering fat a bit. Not low fat obviously but cutting out a little fat to lower calories so the extra carbs aren't as much of an impact. But if you are comfortable I'd ask over there and see what they recommend. You might read through old threads first and see what you find. Pretty sure this has come up before. Don't worry. You'll find your answer.

Thanks, Shari. I'll check out that board. I am low-carb to lose weight. It's really the only thing that has worked for me in the past, but it's hard to say it's workign at this point if I feel this bad.

Thanks, Ben. I have read Kresser's stuff--though it was a while ago. I don't recall a discussion of low-carb and thyroid function. I'll double-check.

Thanks ben. Glad you got a great rec that is helping. I hesitate to rec this particular board in general as the main site is a huge mess (the blind leading the blind) but the thyroid board has some people on it who really know they stuff. I have watched them help scores of people get their own tests run and properly interpreted and then find a doc in their area who can work with them. Life changing stuff indeed. Just a really great group for thyroid issues.

I think you're spot on with the liver being overly taxed thinking. Also the starvation-like response some people get from prolonged LC. After a life time of high-carb processed food eating, a sudden and prolonged LC approach will result in a shock to the system and a starvation-like stress-response n

There is definite reason to think that eating very low carbohydrate adversely effects thyroid health, yes.

LC people, who have consistenly done LC for extended periods like upwards of 3 months, etc, routinely have low thyroid function. How that relates to Hashimoto's is beyond me.

Tons of stuff online if you search. Chris Kresser, not that I am a sworn follower, has a lot to say bout that on his site.

Stay paleo of course, as food quality has nothing to do with your thyroid function, but eat more carbohydrate routinely.

I will echo what the other guys said.

T3 is converted from T4 in the liver. From what I understand, too few carbs forces your liver to make glucose to feed your brain. Perhaps when your liver is taxed by doing this too much, for too long a time the conversion of T4 to T3 is reduced. The result would be lower metabolism.

Also, I have read that low carb reduces TSH in order to slow metabolism which further lowers T3. I think this ends up being called the "starvation" response. I also think T3 is needed to build new muscle which is key to well functioning metabolism as well.

So, it's not the Paleo part that's the problem. It's the too low carb part.

Paleo carbs are good.The Hashi's is autoimmune and I think has been linked to gluten among other things (NOT AN EXPERT ALERT). Keep Paleo and eat some carbs and see what happens. :)

Are you low carb because you are trying to lose weight? If not then I would definitely raise the carbs and see what happens. Even if weight loss is the goal you may want to raise carbs slightly. Now some do absolutely fine on LC or even VLC but I know that some have had to raise their carb levels to optimize thyroid.

This thyroid board has some excellent voices who can help guide you if you want specific help from other low carber with thyroid issuses. A few of them are genius really. They are NOT paleo though so they can't help you on that front but still a great resource for you in figuring this out.

Some say eating low carb lowers the conversion of t4 to t3 so maybe try upping the carb content a little via fruits/tubers.
