Once upon a time I was the person who inhaled my food and would be finished long before anyone else.
It's odd, but I remember for me that the taste of certain food just drove me
crazy. It was like I had some odd food lust, and I just
had to eat everything very quickly. I can't really explain it any better.
I just had to eat it all
now.
Now, the opposite is true. I am normally the last person eating, and I often find myself apologizing for it!
It took some time, but I was able to retrain myself by using methods I'm sure you've heard before:
* I set my fork (or spoon) down between every single bite.
* I chewed at least 20 times for most things.
* While eating, I would take the time to really
think about what I was eating-- how it looked, how it felt in my mouth, how it tasted, how did it smell before I took a bite, and so on.
* I made sure I was not eating while distracted: that meant no TV, music, reading, phone conversations, nada. I concentrated on my food and eating it, and that's it.
I no longer follow those little rules, but I don't Hoover my food up anymore, either.
If I ever find myself eating too quickly again, then I would return to those strategies. (Doubtful I will, though, since it's been about 10 years now that I've been eating slower.)
