I wouldn't say subconcious as much as I would say wiring. It is how we r wired from even in the womb. Based on stress levels and nutritional status of our mothers. I came from an alcoholic mother and as my doctor says I have an overactive amygdyla. But even if my mother just had bad eating habits that would effect development as well. And the fact that the nutritional content of our food sources has become so poor, it is no wonder that so many of our children are being diagnosed autistic, add, anxiety disorders ect. Mindfulness and meditation however can help to rewire those circuits but does take time and effort. Neuroplasticity.
The 1 to 2 years is based on lots of patients similar to myself and the consistant results he has witnessed in many patients with the same issues as me . Especially the low ferritin. It takes on average 1 to 2 years for someone with as low levels as mine to increase it through diet and supplementation. Some people with gut issues don't asorb iron as good as others, so timelines vary. General timeline but as he says a predictable pattern and one that he sees over and over agan in his practice.
I do not get a feeling that this is in its infancy. Maybe in practice, but he has developed a working model of the brain. Most phsychiatrist just throw meds at without even knowing what causes Depression to begin with. He can tell you exactly what causes depressnon, bipolar, add, split personality, ect.
I also think that he is working on a book that hopefully will change the way we look at mental ilness and the relation to nutritional deficiancy and stress. You will also notice that now a lot of articles are being published about chronic inflammation and the effects on our health. And how they are finding that anti inflammatory drugs are actually working to help Depression as well. Anyways I can't explain it so well as because of my low ferritin my brain functions as someone with ADD.
But I will try to explain why and how the brain specifically becomes inflamed when my brain comes back online;-) anyways hope this explains things a little.
