Maybe. I've heard this sort of story before, and I don't tend to believe it. It's hard enough to estimate how much you are eating yourself, and comparing against others is even more error-prone.

I'm facing a similar situation, but I'm loathe to start counting calories just to confirm my hypothesis. Being forgetful and apathetic about meals almost certainly contributes to why I've maintained a healthy weight. I worry that the rigor required for proper observation will change my behaviour.
