For those of you unfamiliar with him, a quick bio from his website arthurdevany.com
"Called "Superman's slightly fitter grandad" by the London Times and a "patriarch of the Paleo Movement" in the New York Times, 73 year old Arthur De Vany is a scientist/athlete and the creator of Evolutionary Fitness, the first integrated model of Paleo diet, intermittent fasting, and exercise. A former professional athlete and life-long student of exercise and metabolism, he is a living example of what he teaches: at the age of 72 he is 6'1", 205 pounds and has less than 8% body fat. He has lived as a Paleo/Athlete for more than 25 years." (emphasis mine)
I Found and very much enjoyed this clip of his lecture on ZURICH.MINDS. Its science-y but really cool.
Check it out.
