Indeed. I believe this is so because restaurants here do not want anyone to go hungry. That includes people who are rather large. If you must guarantee that people up to say 400 lbs always go home satisfied by giving them enough food, there will be way too much food for someone who is 100-200 lbs. This does place the burden of portion control on the eater, which can be problematic for the eater, but is not so for the restaurant. A much worse fate for the restaurant would be losing customers permanently because they did not serve enough food. There is only one restaurant in the US that I've ever been to that didn't provide enough food and I will never go back to it. (I'm around 200 lbs so I'm not expecting a whole ton either.)
