I have been hyperthyroid for 2 years from 2001-2003...it was terrible...I lost weight....palpitations, was on neomercazole for this time and it somehow got cured. But Hashimoto's (antibodies detected that time only). For another two years, my thyroid was normal. Then again, in 2006, I got diagnosed with hypothyroidism and struggling since 10 years. Nobody knows their thyroid better than any Hashimotos/Hypothyroid patients. It is a horrible disease since thyroid affects each and every function of the body. If you don't take medicines for hypothyrodism, you weight will continue to increase out of control and affect eventually every organ of the body.
I can't risk my thyroid (which is already damaged by antibodies) which is having effect on all mechanisms of the body to save liver or heart because if I don't save thyroid, ultimately it is going to affect all the organs you mentioned.
You are working only on reducing blood sugar level which is a symptom of disease of diabetes. Diabetes happens because of IR and just controlling blood sugar may not help in reducing IR at all. So, cause of any disease has to be treated.
I have autoimmune disease called Hashimotos also where >600 antibodies are found in test for antibodies. The main cause of all these may be an inflammation. So, first we have to try to reduce inflammation by finding what is causing inflammation.
If you are sure about LCHF diet where it cures inflammation and leaky gut also, please give me examples as you said there are 15 inflammation markers. Let us evaluate that first.
