Well, that's complex.
Did I have control over it? Sure. Is it harder for some people than others? Yes, I believe it is. So... is it my fault that I am an endomorph who didn't figure out for DECADES that carbs (any carbs) induce cravings and make it difficult for me to control my eating? When, even now, the ADA and many doctors still spout that "whole grain carbs should be a part of your diet." Maybe for MANY people that is good and OK, but it's not for me and a lot of people. Grains and starches are just bad news for me.
Is it my fault that my metabolism is fairly slow (and I know this is true now with watching how much I eat, burn and lose (or don't lose)?
So... when I get stressed or just want to cut loose and such and my husband who wants to do the same, the results are different. 2 weeks of just eating to fill hunger and "hanging out" for me can mean a 10 pound TRUE weight gain. For my husband, 1 lb, maybe. AND, because I probably ate a lot of carbs, etc, I then have to get over the sluggish blahness I feel to get back to eating right and the desire to exercise.
When one person has to be constanly vigilant and others just have to be somewhat watchful, that's a HUGE difference. And I'm not making excuses. It's a reality.
