This is a really interesting thread, with some great points. The discussion about choice is particularly interesting to me. This idea of
you can choose to eat or not eat - I think it is true to say eating such and such is always a type of choice because you are the person actively doing it and no-one else is forcing you at any point. However, I do feel there is a difference somewhere (certainly with me) in a choice that has a logical root and one that doesn't seem to. So, for example, there are plenty of times where I have been out with friends, on holiday etc etc and thought, "To **** with it, I'm having what they're having, I deserve it, I want to have that" and so on. Leaving aside willpower, I can see this is a choice I make because at that moment in time I want a certain type of food, experience, more than the end goal I'm working towards.
However, I can't believe this is the same type of active choice as when I've tried to quit binging. I get an urge to binge, I spend hours going back and forth on the decision and getting very mentally worked up, saying to myself, "I don't want to binge, I don't want to give up the end goal, but I feel a need to binge, I don't know if I can stop myself." Sometimes I manage to talk myself down, not always. That isn't about having a certain type of food but lots of food, all at once. It is still a choice, in the sense that no-one else made me do it, but it feels a TOTALLY different type of choice to the previous example. (And involves a lot more complex emotional to-and-fro-ing.)
I think it can be dangerous to focus on this too much - it can be too easy to think, "This is the way I'm made, I can't help it, etc" (which I've done) and then I absolutely agree you need to start trying to hold yourself to account a bit more. But... Sometimes it can feel like an unstoppable force. And yes, simple is not the same as easy, but stopping that binging train of thought and emotion doesn't feel particularly simple to me either.
Apologies if this is a little less than coherent - it's 2am where I am.
