@maporsche,
Well, what I was saying before is that there are offsetting differences. He eats more (both portions and snacking) than I do, but is taller. I exercised (everyday stuff) more than him. Etc.
It doesn't apply now because we both work out regularly. What I'm referring to is especially the period between when my daughter was born and when I started to seriously work out, about 2 years ago (moderate exercise before that didn't accomplish much). He started to work out shortly after I did.
But between about 2000 and 2007, I gradually gained a significant amount of weight. Very gradually. During that same stretch, he didn't. Again, it's hard to quantify exactly but from just food intake and behaviors, it would seem that he would be the one to gain weight, not me.
When I was nursing, the additional calorie burn/ loss/ whatever you want to call it was enough to keep my weight in check, so really more like between 2002 and 2007.
I am not a junk food person at all -- I have maybe 3 cheeseburgers a year, if that. I make my own food, eat a lot of fruits and vegetables, etc., etc. The
non-cheeseburger day's meals I described is what I had today.
Even if it's just 200-250 calories a day (I'd guess at least 250/ day from how much I need to exercise/ burn off per workout plus the general metabolism boosts from regular exercise that lets you burn more while resting), that explains the difference. And it's still -- my point -- something that requires that I expend significant effort to combat, rather than just resting on the laurels of eating well and exercising moderately, which is enough for some, like my husband.
