on How do you keep from eating the WHOLE BAG???

Let's talk gluttony.
Do you think about Roman banquets, lasting 10 hours at times, at which the diners retired regularly to nearby rooms, called vomitoriums, to empty their bellies so they could keep eating?

Or maybe you call to mind the seven deadly sins. Gluttony is deadly because if you keep it up, you'll die of one of a number of possible causes, heart attack and stroke right up there.

Have you looked around and noticed Americans are fat? As a group, we're fat. Used to be, Pacific Islanders were the fattest people in the world. Now it's us Americans. Yep, we took over that title!
I personally weigh more than I'd like, though I have lost weight this year. I've got a ways to go.
So why . . . WHY I ask. . . knowing this, do I occasionally take myself off to the store, buy a bunch of junk, bring it home to my den, and eat it up?
I don't just buy the candy bar. I buy the candy bar, the bag of chips, the Swedish Fish, and the 20 oz. root beer. And I eat it all up until I feel absolutely disgusting.
I have a good friend who, incidentally, lost a hundred pounds about five years ago, and has kept most of it off, remarkably. This friend confessed to me that she, like me, cannot have a bag of chips, or Oreos, in the house. She'll eat the whole thing in one go.
Anybody else out there do this?
It's binge eating. And it's not good for you.
Occasional behavior like this, interspersed with exercise, won't result in unhealthy weight gain.
But look around, my fellow Americans. I suspect we're all doing this sort of thing a bit more than occasionally.
Okay, I'm sitting here right now eating Lifesaver gummies, filled with a Skor bar and some cheddar cheese popcorn.

I'm so ashamed. ;)
What's your temptation?
C'mon, fess up. Even the buffest among you likes an occasional binge, right?
The question is, how to curb this behavior?
I'm sure I could Google all sorts of helpful solutions. I'd rather hear yours.
