Ecchs: Satisfaction means different things to me at different times, which is why my trigger foods shift. I don't find it particularly satisfying to be full, though. In fact, I dislike it and when I'm in control, I find satisfaction in just reaching a level where I've enjoyed whatever I've eaten and know that it serves my life and desires. This also applies to "controlled" splurges that I think are a sensible way to blow off steam and release the tension of weight maintenance.
But the issue you raise is so complex that the above represents just one answer I might give.
Moonstone: I was a skinny child, oddly enough. Gained weight in early teens; lost weight to the point of anorexia in my 20s; gained in the early 30s and tried to self-destruct by bullemia (and a few other bad things); got healthy in the 40s but gained lots of weight; lost 100 pounds, still struggling with weight issues (can you tell?

). Story of life.
Time is definetely a problem, but IMO many people (including me) use that as an excuse not to do what is in their own best interest. There is always time to do what we have to do, we just have to decide what that is and then do it. We strategize; we give up other things; we multi-task; we get creative; there's always a way. I tell myself that every single day. Was it Hannibal or Alexander the Great who said: "I will find a way or make one."
So, it is both a legitimate issue and an excuse, I guess!
Re chocolate!

My understanding is that it contains substances that raise endorphin levels in the brain. Vanilla has the same substance, but in smaller amounts (no matter, vanilla is where it's AT for me). I have also read that it affects women differently than men. On the other hand, I've read about studies that show it doesn't raise endorphin levels and doesn't affect women differently. Hard to say. Chocolate and vanilla certainly make people happy, but whether that's just the sugar and fat they put into it and the romantic or other happy associations, who knows. I like semi-sweet chocolate best and that has less sugar and fat, so ...
My personal advice (unsolicited) to all persons managing their weight: Eat the chocolate (or the vanilla).
Resistance is futile.
