> you don't stop eating when you're full - you stop eating when you hate yourself...
>>If the number of all-you-can-eat buffets drops, it's likely because society is starting to advocate healthier lifestyles in my opinion.
The last one I went to gave me a stark realization of what was taking place, I got there with 45 mins left as I was in the same shopping center going hard on upper body workouts at the gym in order to build an appetite and decided an afterwork out steam was a good idea. They were slow paced with anything but my drinks as I was sitting at the bar--which were really reasonable, $1 tea, $4 generic sake! So I ordered several of each.
My apps (veg and shrimp tempura) were most of my meal, it wasn't until the last 8 mins left for Lunch order that they dropped off another paper menu thing, but I saw the people left in the restaurant and they didn't look healthy at all. Most were obese and possibly diabetic, they had tons of sugary drinks all around them alcoholic and non alike.
I just ate like 10 pieces of nigiri (like 1/6 of the sushi I normally could put down at most ala-carte places if I'm really hungry) because I realized that this behaviour of excess is not sustainable let alone satisfying--I left oddly satiated after my tamago-yaki, regardless of the amount I ate.
Because as you said, most of the time you go to these places you eat until you have a sense of loathing about what you've done to yourself.
