My epiphany moment was 7 years ago at age 49 when I woke up at 5 am as I had done for many years, got out of bed and thought to myself “why do I feel like crap?” I have lifted weight since I was 18 years old and have always done regular cardiovascular activity. As a physician, I knew a good bit about nutrition, and felt that I was following a good diet. I ate a low fat diet, balanced carbs and proteins. My paradigm was the old input equals output equation, which I quoted to my overweight patients. But despite what I thought was the correct way of eating and exercising, I realized at age 49 that I did not feel good. I went to Las Vegas to the Cenegenics Institute for anti-aging, was evaluated, and actually took the course and was certified by them in anti-aging medicine. To be perfectly honest, I did not like the gist of the course. They pushed hormone replacement rather than trying to root out the cause of testosterone deficiency in a young male. That introduction led to years of hacking myself and my body with different ways of eating and exercising. I trained for a year with a professional bodybuilder, and got jacked up to 185 pounds on a 5’8” frame. I could barely fit into my lab coat. Then I tore all 4 of my rotator cuff muscles on my left arm doing incline dumbbell press with 80 pounds, and had to have a surgical repair 3 years ago. After years of trying different ways of eating and exercising, I realized that my old paradigm of a low fat diet, input versus output concept was just not correct. So now I eat a diet high in selected fats, and weight train and exercise with much more focus on the outcomes I want to achieve. The results have been nothing short of spectacular.
