Heathpack, thanks for the information about what you do to manage hunger.
I'm not sure what your position is, then. Do you think almost all people are able to manage their weight if they try hard enough? Or, that only a few small number are able to? Or somewhere in between?
I believe some people can lose some weight and keep it off, especially if they started off with a lifestyle that promotes fat gain. But, I think almost no one can kept off more than 40 pounds for more than five years. So, some people will be able to say, lose 35 pounds and keep it off for the rest of their lives, depending on how motivated they are and how bad their lifestyle was to begin with.
It is probably possible to predict how much success a person will have in losing some weight and keeping it off. Possibly, something as simple as monitoring the person's basal body temperature when they diet would indicate, within a week or two, how well dieting will work for that person. Also, measuring certain hormones can tell whether the person is starting out at, above, or below their setpoint. But no one is currently doing this. Suppose we eventually can identify people who are almost certain to fail at dieting -- people whose bodies are below their setpoint, say. Would you still object to telling those people not to diet?
As for whether convincing you not to diet would have been a disservice or not, I think it's too soon to tell. You've done extremely well with weight loss so far, but you hopefully have many, many years left in your life. We don't know what will happen down the road.
