Often, when asked, I don't always give a complete explanation. Diet/Fitness seem to me to be like Politics and Religion - everyone one has an opinion on the subject, they are often ill-informed and loosely based on fact and/or logic, and they are near impossible to change. Not to mention, the emotional and potentially hostile response one might get. My guess is that to most people - those immersed in the mainstream, commonly accepted way of 21st Century life - my lifestyle may seem a bit extreme, or inconvenient. I can say with full confidence, having lived it for years, that it is not. My health-based lifestyle strives to mirror those of my ancestors whenever possible and practical. So, if it seems to differ, be extreme or "weird", that is a recent phenomenon. Countless centuries past and, more importantly, what my DNA expects, is much more consistent with my lifestyle.
Instead, the issue is one of mindset. If you can't think outside the box, then you can't eat or exercise outside the box either. And, like so many others in that category, you will struggle with your health for the rest of your life.
