Rule One: Don't eat when you're not physically hungry. Boredom, nervousness, loneliness, anger, etc. are not reasons to put food in your mouth.
Rule Two: Eat slowly. This allows your brain's "I'm full" response to catch up with your mouth. Take small servings, and after finishing wait a few minutes before getting another serving, to see if you really want it.
Rule Three: Eat well. A smaller serving of truly appetizing food will be much more satisfactory than a larger serving of "diet food" that tastes like cardboard.
I have learned by experience that following these three rules is also good for those of us who aren't diabetic.
Or, at least, it is for me.
IMHO.
YMMV.
IANAN.
Thanks for the advice. I am learning that a lot of things that diabetes is sort of forcing me into are good things that we should have been doing all along anyway: eat better, particularly by limiting carbs, eating more vegetables and being consistent in our diet, exercise more, drink less, even take better care of my teeth.
I'm fortunate in that I don't have a weight problem, so the amount of food isn't as much the issue as the type of food. Although, being type 1, insulin apparently can increase one's appetite, so I do have to pay attention to make sure I maintain my current weight.
