I’ve been doing this for years. Not every day, but quite a lot. Most people in this country simply eat too much — and too often. Just because we can.
I go about 14 hours on an average day, some days I can stretch it out to 18 or more
When I was really strict primal it got to the point where I could skip eating for 36+ hours-—all while hiking/hunting/climbing in the cold all day.
It doesn’t fit my current lifestyle to be that strict these days but what I do manager makes a difference.
