In this Episode, Liz and Dr. Tyson dig into the psychology of competitive athletes - and why that psychology leaves them at particular risk for eating disorders.  They also discuss how intensive exercise affects the body of an athlete, in particular when that body is also restricting food (and even water) intake.  We hear the moving story of “Marie” - competitive runner and martial artist who struggles with an ED.  Her story leads to an intensely emotional moment, where the decision whether or not to walk through a door is a decision between life and death.
