Perhaps genetics has something to do with his hair loss? I don't think that diet can blamed as the sole cause of alopecia. Healthy? Sure. I believe many Americans have a distorted image of what a healthy person looks like based on the prevalence of people being overweight, anorexic, overly muscled, and all kinds of other extremes. What's wrong with Dr. Phil? Looks ok to me. Baldness does not equal unhealthy. P.S.: I have a full head of hair but it has been very fine for my entire life, just like my parents.
