Overweight for as long as he can remember, Tony attributes his nutritionally unhealthy lifestyle and food addiction to an unstable family life throughout his childhood. He had worked in food service management most of his career, but quit when he decided his weight had gotten out of control. Now, at 49 years of age, Tony's weight is teetering on the 400 lb. mark, causing him to be jobless and threatening his future with his fiancée. Without the help of transformational specialist, trainer and bestselling author Chris Powell, Tony fears he will never get his weight and food addiction under control. At the start of his year-long transformation, he learns from Dr. Terry Schaack at the California Health and Longevity Institute that, since he carries the majority of his fat on his abdomen, he is at high risk for a variety of cardiovascular complications. With Tony's health at stake, Chris works with him to undo all of the years of unhealthy living that led up to this point. But the road to health is rougher than Chris had anticipated for his client: During his 12-month journey, Tony faces homelessness, the unexpected death of a beloved family member and a change in his engagement, all while taking on the race of his life to regain his health before his 50th birthday.
