As a teenage boy I could eat anything and never put on a pound. However, as an adult, I found myself putting on weight until I weighed over 50 pounds more than I did in high school. My job as a BYU faculty member involved mostly sitting at a desk or standing in front of a class. That led to physical problems. At age 40, running and even walking produced pain in my knees that reduced my activity level even further. Nevertheless, I accepted this reduction and the accompanying gain in weight as part of the normal aging process. I didn’t worry much about it. I exercised moderately and consumed a diet relatively high in refined flour, sugar, dairy products, and meat, which I had been taught were “good food.”
When I was in my forties and fifties, a high school or college classmate or family member my age, who had been a healthy or even athletic youth, would occasionally appear in the obituaries—usually a victim of a heart attack, stroke, or cancer. Also, among those who were still alive, I noticed a significant number growing (in their own words) “slower, fatter, and stupider” and accepting these undesirable changes as inevitable.
