Of all the "tasks" CK has us do, this is the hardest for me. I understand, to some degree, what my motivators and barriers are but weighting them is hard and they can change in an amazingly short time.

I love the feeling of watching a tv program/movie with a bowl of popcorn and I even love eating an obscene amount of it. But I've been pretty successful with the 100 cal orville redenbacher bags. But the point is that a bad day, a crabby remark from a good friend, feeling unsuccessful in other parts of my life (housekeeping) can make you seek comfort--and then your motivational equation inverts or radically changes. Who gives a flip about weighing 200# or becoming a Type II diabetic?

Also, I remember when my son was a baby and I was very post-partum with some emotional lability. I remember estimating that I had literally tens of thousands more diaper changes ahead of me. Well, he's 17 now and the diaper changes are in the past. But I remember being overwhelmed by that. Similarly it can be overwhelming to think that I will be eating this precise and mechanistic way for "ever".

There are no hard and fast solutions to these things. They simply are. Perhaps the best is to notice when the motivational equation is rapidly changing and then to take the time to pause and ask, "why?".
