Some of the early symptoms are cold fingers, low morning oral or axillary body temperature, and sensitivities to various foods. Don't let it progress into autoimmunity.

These are symptoms of low thyroid function. It's more than likely the people experiencing these symptoms were low on key minerals and vitamins that support the thyroid (selenium, vitamin a, vitamin d, iodine).

The thyroid tends to slow down on a low carb diet. Carbohydrates stimulate thyroid function. On a low carbohydrate diet it is especially important to include enough thyroid supportive nutrients.

The only reason I don't get my vitamin D from cod liver oil is because I can very easily overdose on vitamin A. I really don't do well if I supplement with extra vitamin A.

You might want to look into this supplement as the A to D ratio is almost equal.
600 IU of A and 400 IU of D per capsule.
I take three of these each day during the winter on top of the A I get from meat and do very well.

How do you know/feel when you are overdosing on A?

WOW!!! Thanks so much for that info! I am going to try this because I have been at high doses of iodine. I am going to try to increase my liver consumption and drop the iodine. Will report.

You are welcome, Dr. D! I took Iodine for quite a while to reach 'Iodine Sufficiency' and didn't lower my dose once I was saturated and that is when the problems started. I'm at around 7mg right now and may lower my dose even more. If you have been taking it for a while at high doses it would be smart to lower your dose.  Whole body sufficiency takes about a year to achieve at 12.5mg per day.

After doing some research for the past few days I came across some really interesting information about the relationship between Retinol (Vitamin A) and Iodide uptake: Retinol significantly increases Iodide uptake as well as protein iodination, therefore the more Vitamin A and protein one eats the more thyroid hormone the body produces.

      I've been on a high dose of Iodide for over 3 years now (50+ mg per day). My experiment for the last few days has been to completely stop my Iodide supplementation for 2 days and at the same time increase my Retinol intake. Usually, when I increase my Vitamin A intake to current levels (even initially) I get the symptoms I mentioned earlier in this post. Well, the symptoms did not show up the first two days while doing this.
     
      Today I decided to supplement again with a much smaller dose of Iodide (7mg) and to continue eating higher amounts of Vitamin A and so far so good! I actually feel even better!

So my conclusion:

Too much Iodide can cause Hyperthyroidism (this is proven in studies).
Combine too much Iodide and Vitamin A and you get symptoms of Hyperthyroidism which are identical to the symptoms I thought were being caused by too much Retinol.

Thanks for all the replies!

     
   

Thank you for the great info, Inger! I'm going to experiment and try purchasing some lamb liver instead of beef liver in the future. Btw, the symptoms of high copper and high levels of Vitamin A are very similar. Maybe it is the copper after all. Also, Vitamin C is known to help flush out excess copper and whilst being pure carnivore (eating mostly muscle meat) I don't seem to get much of it. Maybe this is why some on this forum do better eating larger amounts of liver.

I eat about a pound of lamb liver per week.

Have you been eating a lb of lamb liver per week consistently for a long period of time ?

Thanks for sharing. Are you certain that it was the liver that caused your symptoms? Did anything else about your diet change? I eat a lot of liver, and have never experienced the symptoms you note. I think there are a lot of other pathways involved in Vit A use that are involved in this issue, so if those are damaged or inoperable in you then you might have other issues to deal with that contribute to your problems.

With respect to the amount of VitA in liver, there's a huge amount of variability for all foods with respect to their nutrient densities. Some liver will have lower VitA, others will have much higher.

When I reduced the amount of liver I was eating I started to feel much better. That was the only dietary change I had made at that time.
Perhaps damaged pathways or perhaps optimally functioning pathways?

I've read that toxicity in the liver can occur at intakes as low as 15,000 IU per day as well as possible negative effects on bone health above 4 or 5,000 IU's (if I remember correctly).

How much liver are/were you all eating per day/week?

24isours, very useful information! Thank you so much for sharing. Sounds like the perfect diet 
I have upped my fat a lot last days, I eat just plain GF beef fat and I can eat so much.... I am going to try your WOE and add even more sea salt to my well water. Wow... this is going to be a very cheap WOE too... 
I am thinking of using only seafood and grass fed organs for my protein. I have so many lamb hearts, kidneys and livers in my fridge right now!

Glad to share! Yes, it is cheap but effective Great, good luck! Keep us updated. I'll be lurking around, so if I could be of any help just ask!

Im 73inches 144lb and i do not eat any salt almost since i tried to to increase salt and got total fatigue. I could not get out of bed almost. This was salt from cheese. Im trying to gain wight by lifting weights.

My main problem is that im having this white coating on my thong no mater what i eat, it dont get better and it dont get worse. Also im never hungry or thirsty and that makes it hard for me knowing how much i should eat. I usually start to burping after i eat any crabs and when i swallow it feels like air is coming up hindering me from swallowing. I try to eat two big meals a day one in the morning and one in the night. Have tried one meal a day but that got me way to weak.

What i eat is usual (for one meal), 200g lean meat (fish, beef, moose, deer, mutton) and 200g of bone marrow, or beef fat OR 120g butter. I try to get about 2000kcal from fat and 500kcal from meet. Most often i can not eat this much.

Have you tried completely cutting dairy( including butter)? I wouldn't recommend getting extra salt from cheese, rather sea salt if you could. Dairy can cause lots of problems.

I've been at 250g Fat / 70g Protein daily for quite sometime.
I supplement with 4-5 teaspoons of sea salt per day to keep my body functioning optimally.

i understand that most on this forum don't think that a ZC diet is healthy, and that organ meats are essential. but in 7 months of ZC i've almost completely eliminated all signs of a lifelong candida infection, not to mention carpal tunnel/arthritis and a whole host of other undiagnosed mental/physical issues. no signs of any vitamin a deficiency here. the only setback i experienced was when I started eating organ meats, so based on my experiences it is not essential in a ZC diet.

That is wonderful, glad to hear it! So, how long were you without a source of Vitamin A?

It's surprising to me that I haven't noticed more problems from liver intake, given my own zinc-deficiency and copper-overload symptoms. I can't currently explain it.

I can't recommend a muscle-meat-only diet, in part because over the past 4 years or so, most of the people I've seen adopt a ZC-type diet have eventually reported problems and added other foods back into their diets, with subsequent improvements.

With proper dietary and lifestyle adjustments ZC shouldn't be a problem.
