Not my evaluation, but in his own words.

A doctor who taught medical school students has his own "come to the truth" time in his life when he suffered from several of the medical conditions he taught about. What he came to realize is that modern medicine when treating non-infectious diseases is so often treating the symptoms of the diseases with drugs rather than getting to the root cause and curing or reversing the progression of the disease.

Many of the doctors I follow have had similar experiences. They themselves developed health problems while following their own advice. Then they looked for answers beyond what they were taught in medical school and found them in lifestyle changes.

His book, "Lies I Taught in Medical School". I just ordered it on Audio Books.
