nice... the season cycling insight is smart... yet one question pops up - how old is agriculture relative to the length of time our progenitors spent eating meat for the vast majority of their diet, likely during all seasons...

one of the things Champion digs into is that issue - im new to his book so dont quote me - but I think he argues that we simply have not been eating carbs and veggies in large amounts for long enough to change the underlying adaptive sets of our cells and mitochondrial processing which all "evolved" based on converting fats and proteins, and which now depend on such for optimal function...

he also coined the term "glucosis" which is a nice term methinks.
