dstalksalot, the whole issue of calculators, RMR and TDEE got started because I was gaining weight on what I thought was about 1300-1400 cal/day back in the summer and early fall: I then cut back to 1200 cal for about 3 weeks and didn't lose a single pound. As you can imagine, I was severely upset. The last few months have been a quest to figure out what I was suddenly doing "wrong" after being a successful maintainer for nearly 3 years. Those calculators are one of the things that has puzzled me, since I hadn't been eating at anything remotely close to my TDEE, yet wasn't losing weight. I still haven't solved that mystery completely but I think there are 2 factors that go a long way toward explaining the discrepancy. First, I think that like many folks, I was underestimating my calorie intake by a few hundred calories on many days, either by willfully failing to document indulgences or, more often, by doing "dissociative eating" - taking 3 handfuls of almonds but only consciously registering (and accounting for) the first one. The second factor is that it turns out that there is a HUGE amount of "flex" in your non-exercise daily activity, and that to a great extent, if you exercise more or eat less, you will unconsciously economize on movement the entire rest of the day to prevent weight loss (your body is in it to win it). The difference can be hundreds of calories a day, causing a TDEE that "should" be 2000 to be 1700. The 3rd explanation, and one which I am highly skeptical of, is that you can "wreck" your metabolism by eating at too great a deficit from TDEE for too long, and drive down your RMR by hundreds of calories a day. Most scientific/medical studies I've read on the topic say that this is BS, that you can't lower your RMR by more than 10-15% (and it takes actual starvation/severe anorexia, not just a moderate binge-eating disorder like I had), but there are a lot of smart people on the internet claiming that they've "fixed" a slow metabolism by eating more (a lot more) calories every day and putting up with a temporary weight gain.

Michele, I laughed at your statement "I would kill for her body. Possibly literally." I had a vision of you as a body snatcher for a moment :>) I too hate the pretense of insincere self-deprecating comments - that teacher sounds just like girls I used to know in H.S. and college, though thankfully not so much these days.
As for the next iteration of this thread, I'm wondering if we should name it something more in keeping with its actual raison d'etre, like "maintainers' weight battles" or "maintainers talking about diet and exercise plans." This perpetual "5-10 pound weight loss" thing doesn't seem to be happening for most of us, and like Allison, the title of the thread itself is making me feel bad.
