Meet two more people joining The Doctors Fast Burn Challenge: Joanne and Thunder. Joanne really enjoys food and Thunder shares that he came back from Iraq struggling with PTSD and gained a lot of weight for the first time in his life. Dr. Ian points out that there is a strong mind-body connection when it comes to shedding pounds. Also, Joanne has set a fundraising goal for Literacy Chicago. She hopes people will pledge a dollar for every pound she loses.
