Ancestral eating removed mental fog, fatigue, and confusion for me. Those weren't my primary health concerns, but there is a significant difference in my mental performance when I completely eliminate field-agricultural foods and processes from my diet. I have a somewhat dangerous job that requires maximum alertness and the ability to make quick and correct decisions for prolonged periods of time, kinda like an air-traffic controller, which I am not. I have fun at work when I'm completely alert.
I, too, do not say I'm on a paleo diet, since that has come to mean "coconut-flour bread" and "chia-seed pudding" in popular usage. Paleolithic people didn't have recipes, food-processors, refrigerators, etc.
