His friends and family have been sharing stories, about people they know, who have found success on a variety of popular diets, and one friend even asked that he consider weight loss surgery. Jack doesn’t want to go to the extreme, but based on his frustration, with not being able to manage a healthy weight, he has not completely rejected the idea.
