I'm curious about my RMR or BMR or whatever because it seems like no matter what I eat my body doesn't store fat. If I super pig out I might feel a little puffy for like a day and then I eat lightly and feel bad to normal. I'd be interested to see just what my metabolism is (or as close as they can get with one of those breath tests or whatever), and how it changes over time.
I'm not sure it's incredibly rare, but it's not extremely common either. Having thyroid problems is certainly not true of most people who are fat. My friend is only a little overweight and it does seem to be something other members of his family have had to deal with. It's not like he ate normally and had a low metabolic rate, he tended to have low caloric intakes on dietary recalls.
Do you fidget a lot or tend to act very animated? Some of the more recent evidence suggest fat people are very economical in their movements, while skinny people are not. I'm not sure how good the causality is on this though. Your BMR or RMR wouldn't pick up on these kind of differences.
It might just be as you described, one day you eat a lot, next day you eat light and ultimately it's balancing out, so your not gaining weight.
