Does eating LC/VLC induce hypothyroidism?

Answered on August 19, 2014
Created June 04, 2012 at 5:15 PM

My family has a history of hypothyroidism. For the last 6 months I would say I have eaten pretty low carb except on workout days where I would add in a sweet potato or 2. I also intermittent fast and when I started that I would get horrible bouts of feeling cold to the bone even though I still had body fat. I am thin except for fat around my stomach, which I can't seem to lose (though that may also be because I overeat). Also, I may add when I was intermittent fasting then it was like 18 hours every day. Now I do 16 every day and 24 hours twice a week at most. I take my temperature regularly and this may not seem too irregular, but it is somewhere between 95-97 degrees. It never gets to 98, even when I have a high carb day. Should I be concerned I am giving myself this horrible disease? If so, what should I do to fix this?

i seriously don't understand why anyone would fast for 24hours TWICE a week. VLC for the rest of the week, and still think you eat to much. Sounds like a eating disorder to me.

Scottts seems on the right path.Go to perfecthealthdiet and devour all the information you can. I am no expert, but maybe try a week of light fasting. For breakfast eat some fat, protein and safe starch. Maybe do small fast until dinner and eat more fat, protein and starch. Monitor your body temperature at morning and night and record it to a chart. Try it for a week to see if anything changes. Look into MCT oil as well. I have this with coffee in the morning and I am sweating shortly after. I am not an expert, but this information isn't anything too dangerous. Give it a shot and report back.

What do you get iodine and selenium from offal? Because I don't eat it.

If you want to do any 24 hour fasts you should do them only once per week. The rest of your eating for the entire week should not be IF style with excessively long durations between. So do that OR you can doyour daily IF with that 16 hour window etc. pick one.

The lowered t3 levels is a pretty big indicator to me that low carb diets are adversely affecting thyroid. I personally think you can be hypothyroid with no apparent symptoms, not to mention the many little things that can go unnoticed that could indicate a thyroid issue.

Temperature is a little low, I would avoid IF. Raising temperature doesn't only depend on carbs, but also on salt, thyroid hormone, protein ingestion, ...

Your excessive fasting seems to be an issue to me. IF can be a useful tool if it is done correctly,but it is not magic nor is it for everyone.

If you believe you are eating too much,then you should start a food log along with a calorie count to get a better idea.

Dieting in general may be the real culprit.

I'm hypothyroid as well. I found over the last year that VLC (less than 40 gm carb/day in my case) causes my TSH to rise a lot and I feel horible and cold.

I found that raising my carbs to about 80 gms or more per day, mostly from starches like rice or potato, or from small amounts of dextrrose (glucose) made me feel MUCH better and eliminated my coldness.

I eat kind of funny. My breakfast is Bulletproof coffee (just search on this term to learn more). 3 tbsp ghee plus 2 tbsp MCT oil blended into 12 oz of coffee.

I don't eat a solid meal until dinner when I have all my carbs and protein. I eat 2 oz of a grassfed liverwurst to get selenium and copper from liver, heart, and kidney. These trace minerals seem important for proper thyroid operation and lipid control.

My current daily macro target is 88gm carb, 62 gm protein (I only count animal proteins), and around 150 gm fat. This way of eating has optimized my physical and mental state os far. I've lost 35+ pounds as well even on 80+ gm/day of carbs and NO excercise.

I really recommend the Perfect Health Diet blog. There are some posts about low carb and thyroid that convinced me to up my carbs via starch and to limit my protein intake.

Good luck.

Does a low body temperature create a conducive environment for infections? I heard Paul Jaminet talk about this. I have no scientific background, but this just makes logical sense. If the body temperature rises to fight off an infection, how can a lower body temperature be better for health? Maybe a low body temperature and living in a bubble is the best path to longevity.

No diet adequate in iodine and selenium will cause hypothyroidism, which is either the failure of the thyroid gland to produce sufficient thyroid hormones (primary hypothyroidism) or the failure of the hypothalamus and/or pituitary gland to produce sufficient stimulating hormones (secondary hypothyroidism).

Reducing carbohydrate in the diet will also reduce the blood serum level of the active thyroid hormone (T3), but there is absolutely no evidence that this reduction in T3 causes fatigue, cold intolerance, lower body temperature, or any other symptom of hypothyroidism. In fact, the evidence we do have shows that basal metabolism is a function of calories, not carbohydrate.

If you experience any of these symptoms, it's because your food intake is too low or because you actually have hypothyroidism.

According to Dr. Ron Rosedale, you're supposed to lower your body temp when you eat low carb/high fat. It's a longevity thing, as apparently centegenarians all have low temps, low thyroid levels, low insulin, low leptin, etc. He says it's about efficiency of your "fuel" (read "food"), and causes you to live longer, just like higher quality gas causes your car to last longer. Or that's the theory anyway. I'm a thyroid patient, and also very low carb (under 50 per day), and my T3 and temp tested out-of-range low, so I wrote to Dr. Rosedale at one point, asking him whether that was something to worry about. He answered me and said it was just a sign that my low carbing is paying off. So unless you're actually cold when others are not, and have other hypothyroid symptoms (hair falling out, constipation, brain fog, etc.) I think he would say you're ok. I just finished reading a thread on this site that goes into it in detail, but didn't copy it. Sorry.
