One question I often get is how much energy should I spend at exercise?
My answer is always: not much. Energy expenditure in EF is rather moderate. We spend energy in our basal metabolic rate by building muscle and the capacity to do things, not in the energy we spend in our exercise. The quality of life is the energy we spend in living, not in exercise.
I find it very satisfying to have been applying both these ideas---glucose restriction and exhaustion of muscle glycogen---to my own life for over two decades, long before they were discovered in the lab.
One of the many interesting people I have met as a result of this blog is a distinguished physician/psychiatrist who treats people who have metabolic problems and are overweight or obese. He argues that I am a proof of concept for my Evolutionary Fitness Way. That is to say, I am an exemplar who represents an outcome of following the EF system, an existence proof of the efficacy of Evolutionary Fitness. Everything I say here is also true of WW who celebrates her 72th birthday this month.
In that spirit, I wanted to compare my body mass, strength, lipid and hormone profile to the 28 year old experienced weight trainers studied in an NJM article. I want to show that the conventional wisdom that aging causes a decline in muscle mass, increased obesity, a fall in testosterone, and an unfavorable alteration of blood lipids is not true. So, what are the relevant facts?
