Before it started airing, I was hoping it would be more realistic than some of the other shows like Biggest Loser. It represents a powerful platform for delivering information to the public regarding weight loss, clearly an issue of importance when two-thirds of American adults are overweight or obese. Unfortunately, I think it raises many of the same concerns, in particular, an insufficient emphasis on achieving safe and enduring change. In the process of condensing one year down to one hour, many things that people trying to lose weight need to pay careful attention to get lost. Issues like determining a safe and realistic rate of weight loss, beginning exercise at an appropriate intensity, the role of medical supervision in the process, and how to cope with the challenges of adherence. If it helps motivate people to get started, that’s great, I just worry that it perpetuates many of the myths that lead most new exercisers to quit within the first three to six months.
