One of the exercises in the
Beck Diet Solution book really spoke to me about this issue. One of my great fears is to be hungry (even though I've fasted up to three days for religious reasons). I know that when my BG is low, I get "grumpy" (my family would use another term). For years, I've used food to self-medicate. With my insulin resistance, that's why I was never satisfied with higher-carb plans... I'd eat and eat and still be moody and hungry.
Anyway, that's why I'm so afraid to be hungry. I carry snacks in my purse. I plan my travel around food.
So this exercise helps you face hunger, so you can actually recognize it. You eat a normal breakfast, and skip lunch. But not just skip it... you look at how you feel, and rate your hunger on a scale of 1 to 10. You realize that the memory of hunger, and the fear of it, makes you think it's going to be an 8 or 9... but it doesn't really get much above a 4 or so. It was eye-opening to me.
So when I'm hungry and it's not yet time to eat, I seriously consider whether I'm really hungry (8+) or just "snacky" (3-7). When I think about that, I can almost always say to myself, "Yeah, I could eat. But it's almost dinner (bedtime, lunch). So I'll wait."
It's been liberating!
