"World Carnivore Month" January Challenge!
Today is the first day of January and is also the first day of World Carnivore Month. To that end, let's challenge ourselves to eat a carnivore diet for the entire month of January. The type of carnivore diet and the level of strictness you choose to do is entirely up to you. Examples of carnivore diets include the following... 1) The Lion Diet. A person eating the Lion Diet only consumes the flesh of ruminant animals, water, and salt. 2) The BBBE Diet. BBBE is an acronym for Beef, Butter, Bacon, and Eggs. 3) The Carnivore Diet. This allows for the consumption of any and all animals and animal by-products, including dairy. In any of the above examples, the object of course is to not consume any plants as part of your diet. Of course, we're not going to micromanage hoe you prepare your food, so your use of seasonings is entirely your own personal choice. IF your circumstances don't allow you to go full on carnivore in January, then you can participate in this topic by challenge yourself to do better, above and beyond what you have been doing. For example, if you have still been eating grains, seed oils, refined sugar, or drinking alcohol, challenge yourself to avoid these items and just eat a clean, single ingredient whole foods diet such as clean keto, ketovore, or animal based. We encourage you to check in daily, and share what you have eaten, perhaps a weigh-in if you're willing, and enjoy in some small talk. Participants in this topic will be entered into a drawing for a prize at the end of the month.-

After about 2 years on Carnivore diet I had a major shift in thyroid condition. I went from extreme hyperthyroid (graves) with a fairly large goiter on the right side of my neck to extreme hypothyroid. I first noticed the goiter starting to get substantially smaller about 1 year ago. Then symptoms of tiredness and being cold all the time came along. In addition muscle fatigue and weakness set in and then eventually neuropathy in my feet and fingers. I could hardly hold my arms over my head to wash my hair. I'd go for walks in the summer but could hardly walk around the block as my legs would suddenly get very fatigued and low back get sore so I decided to come off carnivore for a while to see how that was going to go. More recently my lymph-nodes have swollen quit a bit, it seems the enlarged goiter had moved into the lymphatic system. I now noticed I have sleep apnea and drooling on my pillow along with dry eyes and change in vision.
I was also taking Ivermectin daily at 0.4mg/kg so it left me wondering if it was the diet that caused the shift or the Ivermectin or the combination of both.
I will admit I may not have been eating enough fat and or butter on carnivore and that I mostly ate grassfed/grass finished organic beef as I am friends with a farmer who raises certified organic beef.

My Dr told me that after many years with hyperthyroid that my thyroid simply burned itself out and of course wanted to immediately put me on syntheroid. I understand that this is the only explanation the Dr is allowed to give but I think it's total BS
From what I've read and watched in video's Carnivore is supposed to be good for hyperthyroid as well as hypothyroid so I'm left wondering what happened. Has anyone had a similar experience? Anyone have an idea of what's going on with me? I want to go back on Carnivore but don't want hypothyroid to get worse than already is if that's even possible. Any input, opinions or help understanding will be appreciated and welcomed.
