10 years ago, I had a tumor on my thyroid and had the whole right gland cut out. I had to take levothyroxine pills for Hypothyroidism ever since. My symptoms never improved despite taking the medicine. I just followed doctors until I couldn't stand it anymore and started looking for a different way of solving the problem. And I found it ; ) But fasting will not help long term if one does not change their eating habits, especially with autoimmune diseases. Also, I didn't get better until I started doing enemas and completely cleansed my big intestine.

You should read about the food combining rules and possibly do food intolerance tests. food intolerance is a really big thing when it comes to autoimmune diseases. Before you do the test and you know for sure, I would cut out all the grains, nuts, dairy and eggs from your diet.

Food combining is explained quite well here:

However, I don't agree that eating meat is unhealthy or unnatural. I believe good meat (without Antibiotics and hormones) is crucial for health. Same with unpasteurized diary if you can digest it.

I don't eat any grains, except for white rice (occasionally).

I hope it helped : ) Let me know if you have any questions.
