Hi Irat, maybe this is the case, maybe what we consider healthy is not healthy at all? Like for example the fact that a lot of people are creating gallstones or calcifications, which is not a natural process. Why not to investigate it, I think we should investigate everything. It is possible that it is more than one factor that creates CFS. Maybe it is liver not working well along with something else? I think it can be difficult for researchers to find a mixed cause.
Dr.Ray Peat for example he has very good detailed informations on how the body works when becoming sick how the systems change and about learnt helplesness.
....Anthony Williams like Tammy said is Medicinal Medium he has easy to read stuff as well online,but i don t agree on everything .he says .and he is into fruits and detox which is not for me ......but I know many who swear by it
.and others like Marry Ruddick (back to joy) I like infomation wise,but she is on the low carb/keto site which is not for me either lol,but has studied ancesteral tribes and also uses limbic system retrainung .....
Dr.l.wilson the development programme, also good on how the body operates when sick,and how to remineralize and change the symphatetic dominance .,bit in Chinese medicine direction
Anyway one does not have to follow anyone's protocol in order to heal,only learn and doing what's best for oneself,and combine informations,
I give you the links
( All of the have their broadcasts /channel on you tube if listening is preferred to reading)
