I was going to blog about Tara Parker-Pope's recent article "The Fat Trap," but then I noticed a lively discussion at Megan McArdle's blog. I participated as "bearing." You may find that comment section interesting if you follow the weight loss/gluttony threads here.
Pope's article is about how hard it is for people to keep the weight off, when they have lost weight through medically supervised severe calorie restriction. Some people do it through obsessive calorie counting and abnormally high exercise regimes.
I am pinning my hopes on the "sustainable, real-life habit" approach to weight control, something that is almost the antithesis of the medically supervised fasting. But I still find articles like Ms. Pope's article depressing -- and frightening. It's not that I can't keep my weight within a good range now. It's that I fear I will somehow lose the will to keep working on it.
