My doc treated me for type II diabetes with a low carb Paleo diet in 2004 before anyone heard of Paleo. He also advocates fasting. I reversed it by losing @75 pounds.

I follow Dr Jason Fung now for my fasting protocol. He has great podcasts with Jimmy Moore and YouTube videos too. He is a nephrologist (kidney doc) and has reversed diabetes by fasting his patients. He is interesting because he has placed hundreds of patients on fasts.

I do it for weight management. I have heard Dr Fung talk about brain benefits, but more along the lines of preventing dementia. I’ll listen again and report back if I have it wrong.

The most important thing I’ve heard is a ketogenic diet has benefits for bipolar, just like it does for epilepsy. I found this fascinating because anticonvulsants treat both disorders.

Ketogenic or even just plain old Atkins diet is known for resolving seizures in children.

Fasting would operate on the same principle if you fast long enough to burn fat stores, and even better-go low carb between the fasts.
