I've noticed the descriptions of the MBTI types commonly talk about how it affects and relates to careers, relationships, parenting, and the like but rarely do I see anything about how it relates to diet and exercise. As a personal trainer, I'm curious to see if there is a link, and am beginning my investigation by seeing if there is any correlation to Dr. Kushner's Diet Personalities and the MBTI types. I'd really appreciate it if you could take my survey!
