I followed a primal diet for a few months and over time I became chronically constipated having a bowel movement once every three days. I tried upping the fat and that would help for a while but eventually I would plateau and fall back into bad bowel habits. Ever since adding grains like quinoa and brown rice, I've been having a bowel movement just about everyday. My theory is that fiber really is essential and I wasn't getting enough when I was primal but adding in the grains worked like a charm.
