Oh dear! I must admit to being over-frank on this thread, but to be honest, I'm sick and tired of biting my tongue in real life, when I see grossly overweight people insisting they don't overeat, when I've witnessed for myself them stuffing their faces over-imbibing on a regular basis. I'm more inclined to respect the chubby person who admits to eating too much, at least they're honest about it.
Re your arguement, a valid one I admit, that you can easily gain 20lb in 20 years by simply putting on an extra pound every Christmas, that's true. But it's equally true to ask just how easy would it have been to take off that whole pound over the course of the following year? Pretty easy I'd say.
I'm glad you acknowledge that your weight gain is your own fault, and that you are doing something about it. I've heard all sorts of excuses, call them reasons if you will, for gaining copious amounts of weight, I've watched alcoholics drink themselves to death and smokers who apparently can't stop even with heart disease.
I've walked in my own shoes too Baden and come through situations you couldn't even begin to understand, just in case you think otherwise.
