I'm a fellow fast eater, but I never used to be. I think retail work "broke" me; when you ostensibly get half an hour for lunch, but it winds up being fifteen minutes because it's during Christmas, and then that fifteen minutes gets cut down further with cooking time and such, you're talking about HAVING to inhale food if you want to eat at all.
I've tried the recommended techniques for slowing down--take a "mid-meal break," put the fork down between bites, sip water between bites, chew each bite N times--but they feel weird to me even after a month of giving them a fair and honest shake. It actually
reduces my meal satisfaction as I'm spending too much time focusing on what are "appropriate" bites and pauses. I don't want my mealtime thoughts to be "Okay, take a bite...not too big...chew chew chew--how many times have I chewed, I lost count...set down the fork...NO! NO! Don't pick it up yet! Count another ten seconds!...breathe...wait, did someone say something to me?...crap, he did and now I lost count of how many seconds I should wait..."
ARGH. No way.
I already weigh my food to the nearest gram, eat off of smaller plates, use smaller utensils, and count calories. That's enough structure and control; I'm not going to count bites and seconds as well. I tried it and it didn't "take." It never has.
If you can learn to be a slow eater, more power to you. If you can't, don't think it dooms you to being unsatisfied with your food. Just add more low-calorie volume with your meals. I don't enjoy a meal in which I'm setting down my fork and counting seconds until it's okay to pick it up again, but I don't mind one in which forkfuls of meat loaf are separated by a few bites of asparagus or broccoli or salad.
Other possibilities include starting your meal with a bowl of light soup, eating the bulkiest stuff on the plate first so it has more time to send "I'm full" signals to your brain, and changing around your meals so that you eat smaller ones more frequently/bigger ones less often, whichever you find more satisfying.
