I have several friends who have lost weight and kept it off. I also have several friends and multiple acquaintances (sp) who have regained much of the lost weight, whether from diet or surgery or both. It seems to me to be that those who kept it off have realized they needed a new eating lifestyle, those who didn't, went back to old habits.....often because they "deserved a break". Of course weight issues are more complex than "habit", but it's part of it.
If healthy eating becomes a habit, I think that with "a break", one jumps right back on the healthy eating track.
If it is perceived as a short term fix, then the weight comes right back on. (at least this is my personal experience-the difference betweeen what I am doing now, and in the past is I am treating myself with on plan treats when I feel the urge, and non-food treats more often than not!!)
