Low carbs and T3/RT3 levels

Answered on August 19, 2014
Created September 19, 2011 at 11:12 PM

Is it true that eating VLC or Zero Carb will cause my T3 levels to plummet and raise my Reverse T3 levels?

And if so, will this bring weight loss to a screeching halt?

Again, if so, what do I do about it? Eat 50 grams of carbs per day? 25? None?

Cody, I've started a thread about low carb and lowered T3 here: http://paleohacks.com/questions/78343/is-lowered-t3-resulting-from-a-low-carb-diet-problematic

Yes, Dr. K, thanks for chiming in. Cody, it was the last 40, and I'm still ZC, or very close to it, and more or less at my optimal weight (being female, I never quite feel my weight is optimal, lol). Increasing my plant food intake (I've tried it twice in the last two years) results in rapid return of joint pain and weight gain, so it's meat for me.

Maybe I should look into an Iodine supplement. I take selenium now. What about the various cofactors?

Dr. Kruse, thanks for weighing in here. So following the leptin reset protocol, and getting good sleep will keep my thyroid humming along? Rose, was that the last 40 or the first 40? Did ZC get you where you wnated to go?

Light exposure and circadian rythmn dysfunction play a lot bigger role than carbohydrates do to the pineal and pituitary axis.

Rose your response is often seen in clinical medicine. Many of the recommendations made in this situation just don't match my own clinical experience.

I've heard many times that LC/ZC "causes" hypothyroidism, or at least thyroid problems. In my case, my weight loss thudded to a halt on VLC, and picked waaaay back up on ZC -- I lost 40 of the 70+ I had to lose only after going ZC. So, mileage varies.

Some folks seem to really do okay on VLC diets. A few anyway. Not all though - not even most.

I think Paul Jaminet makes a good case for ingesting around 100g of starch per day. At first I couldn't do it - triggered binge-y behavior. I kept trying though, occasionally, and now I can do it without issue. Every day.

Per the PHD's version of paleo, I don't count non-starchy veggie carbs, just the starchy ones. I eat lots of veggies, organs (not just liver), fish etc.

If you supply your body with sufficient nutrients, your thyroid will have the substrate to get the job done. If you are short on substrate (iodine, selenium, various cofactors), problems ensue.

It's called Euthyroid Sick Syndrome, and I highly recommend checking out Paul Jaminet's posts on it over at the Perfect Health Diet website.
