My mother (in her 70's) is doing that plan, and she lost about 7 lbs in the first two weeks while feeling more healthy and energetic than in years. She feels it is a healthy way of eating that she can stick with long term.

I'm going to look further into the Dr. Phil plan as I get closer to maintenance. I think it is pretty sound, but with my history of out of control insulin response I might need to be a bit lower carb than his standard plan.

I found his weight loss shows very helpful in breaking a big stall I had last year. I was following my plan and stalled while his people kept losing. It drew my attention to my portion size, which I first modified by eye and then later with calorie counting. Weight loss took off again. and I've lost more than any of his challengers now (of course, it took me longer to do it, but I'm still proud of having los more than even Jim!)
