Edit: through all this wall of text and I failed to mention my wife is Korean. I met her here in North Carolina.
There was a joke I heard on TV when I was a kid in San Francisco.
“Why are asians so small? You try eating rice with chopsticks” {laugh track}
Ok, its borderline racist, and I never found it funny, but I could see where the humor is trying to be placed. So whoever wrote that joke, was in it for very cheap laughs. I’m not asian. I eat with chopsticks everyday, pretty much. I would safely say i use them more often than anything else. Moreover, back when I did eat rice everyday, I did use chopsticks. When you know how to use them you can eat anything with them.
Pro tip: practice eating sautéed button mushrooms. Little marble like shrooms slippery as whale shit on an ice flow
Ok, all that for a cheap laugh.
But on cultural eating. Something I noticed in San Francisco, and in Korea (I was stationed there for 1 year) the locals, and my asian friends in S.F., didnt eat themselves into a coma like us westerners do. They didnt snack. And they worked very, very hard.
I spent most of my days off, as well as general off time, in a local coffee shop. I loved it there. Nicest people I had ever met. And I’ve been to a few places around the world. The coffee shop opened at 0600. It closed at 2400. (6 am to midnight). It was one shift. Same people working the entire time. They had two days off a month. Not a week, a month. Two days off a month was considered luxury as well. Not many other shops near the Air Base took as many days off.
Very often I would be there as close to opening as i could, and stay as late as I could. They were truly gracious. They invited me to eat with them, and I would on occasion bring something from the base. Popeyes chicken strips were a favorite.
And the owner of the shop (had to be in his 70’s) loved Shivas Regal. Took me a while to figure that out. He called it Sheeba’s. Thats how i heard it anyway, lol. It was in that shop that I taught myself to read and write in 한굴 Hangul. I think i spelled it right. The korean alphabet. Read and write yes, translate, no. I never had the time for a formal class.
So pretty much everyone I had a meal with there, ate sparingly. But they always made sure their Miguk 미국 (American) friends had plenty on the plate. And I learnedbits an insult not to eat everything on your plate. So you only ever take the amount you will eat.
The point was made to me once at a restaurant that I needed to finish eating because ‘they have family living up north’ that are starving. So wasting food was an insult to their memory. Talk about feeling like the “ugly american” 
Ok, that was wildly side tracked. But again, I think other cultures, other than modern western culture, just see food as something they need to do and do it right, and in moderation (“do all things in moderation”). I can only speak for myself, but I used to eat for the joy of eating. I might have just ate three full plates at the buffet, but that pecan pie looks too good to pass up. I better get a plateful of that, maybe seconds while im here.
I used to eat that way because I could. Food was food. The only limiting factor was if you had to losen tour belt to stand up. Signals time to stop.
The modern, enlightened, know it all western culture has done a serious disservice to the rest of the world. We (the nebulous we) gave the world electricity, light, refrigeration (?), telephones, radio, TV, internet, and disbetes.
