Except portion size in a lot of Asian countries is LARGER. It is WHAT they're portions of, and how satiating it is that matters. For example a popular Asian Fast-Food dish might be a huge bowl of udon noodles, with assorted veggies (e.g. bok choy, carrots, mushrooms), a little meat/tofu, in a salty broth. 500~ calories total. Then add on a Green Tea/Thai/Jasmine/Oolong Tea at an additional 100~ calories or less. A McDonalds large french fry is also 500 calories alone for comparison. A Big Mac is another 580 calories on top, and a Medium Coke is 200 calories. So we're at 1280 calories for McDonald's most popular meal in the US. I'd put it to people that the udon bowl is more satiating ("filling") than the Big Mac meal by a lot. It is also a large portion. You'll be full most of the day, whereas on the carb/fat/sugar explosion from McDonald's you'll need a snack when you crash late-afternoon.
