That being said, insulin resistance / T2DM is associated with the thinning of cortical tissue [0] - insulin resistance being the typical cause of burgeoning fat storage. Additionally, the brain runs well on ketones [1], which are an abundant supply of fuel on the insulin-resistance-reversing ketogenic diet. All I'm saying is there may be some benefit for the many fat smart people in taking up some kind of insulin-resistance-reversing diet; lo, for all the fat people (, as well as the thin-yet-still-insulin resistant people, too). But ketosis is not exactly the default path-of-least-resistance for most people, given the standard american diet, conventional nutritional 'wisdom', etc. [0] https://www.ncbi.nlm.nih.gov/pubmed/25439756 https://www.ncbi.nlm.nih.gov/pubmed/25439756 [1] https://www.ncbi.nlm.nih.gov/pubmed/15877199 https://www.ncbi.nlm.nih.gov/pubmed/15877199
