When Melissa's military husband, Mike, returned from Afghanistan, he seemed to have become a different person. Later diagnosed with Post-Traumatic Stress Disorder (PTSD), he committed suicide in 2009, leaving behind Melissa and their two sons, one of whom has also been diagnosed with PTSD. In the years following Mike's death, Melissa turned to food for comfort, eventually reaching 301 pounds. Last year, Melissa wrote to show trainer Chris Powell's wife, Heidi Powell (also a trainer and transformation specialist), asking for help. Melissa's yearlong physical and emotional journey will be documented.
