Hello everyone, the RSD has continued to spread and it is full body now. The doctor I am working with has suggested I do a 4 day fast or go on a high fat diet to put my brain and body in a ketosis state. Has anyone heard of this or tried this?

It sounds crazy to me but he said the fasting could allow my body to heal since it won't have to put energy into digesting food and will put my body in a ketosis state which is suppose to be good for the brain.

I'm skeptical, I'm extremely thin as my body doesn't seem able to absorb nutrients very well or eliminate food properly. This is counter-intuitive to me so any feedback would be appreciated! Thanks!
