I started the diet in January at the keto level but had to start adding more carbs in the form of sweet potatoes due to my thyroid. It was great otherwise and various symptoms were going within a week like sleep apnea.
It was a struggle getting the carbs right though, and l would have preferred to go keto.
Then l found an autoimmune protocol group on Facebook for Hashimotos - Elimination Provocation diet, Hashimotos 411, which is stricter and getting good results with many people. I think it is much better than Wahl's for Hashimotos people.
Things started to slow down again though until l read about the work of a neurosurgeon called Dr Jack Kruse and his advice on longevity. He thinks that diet can only get you so far but he has only studied paleo . I have found though that what he says has applied to me
He is about the physics of the mitochondria and the loss of electrons in chronic illness. This has very much been my biggest, problem due to early mercury poisoning. So now l am grounding in wet grass, sun gazing and bathing, concentrating on fish for protein, cold thermogenesis, getting into the sea when possible, high protein breakfast, loads of lightly steamed greens, cutting tap water for washing my body as well as for drinking, cutting out blue light at night, and things have dramatically improved more than at any other time through diet alone. My carbs are coming from plantains, cassava flour, yams, sweet potatoes and berries which Kruse says are needed more in summer, more keto in winter. The rest is fish some meat, salads ghee and coconut oil and pretty easy to do.
I make a bread with green plantains and love it.
The electron thing has been major in my healing. My energy levels have greatly increased and no more pem. Sleep is good in the main going to bed at 8.30 pm.
