Re: low-willpower weight loss, maintaining a routine is much easier than creating a new one or trying to "behave well" outside of a routine. "Pre-committing" yourself to what you're going to eat - and including a moderate amount of indulgences within that routine - is a lot easier than trying to "spontaneously" make good decisions every day. It does require an investment of effort and willpower to kick it off, but if you've written a plan for yourself, bought the necessary ingredients, and try to follow it, it's possible to set up a low-willpower healthy-eating lifestyle.
