It seemed pretty glib to me.

Sure, these are behaviors that correlate strongly with people eating more, but are they primary behaviors that can easily be changed, one by one or all at a time? Or is there something underlying them - a psychology (or reality) of scarcity, excessive susceptibility to marketing messages, true physical hunger due to carb bingeing (associated with lower-priced foods) or insulin dysfunction, something else? And of course, basing all his observations on buffet restaurants isn't representative of either the general population or the daily eating habits of the people he observed.

I've observed the same behaviors he's talking about, and it's easy to be smug and judgmental, but I don't think it's helpful.

One thing I have seen lately is that restaurants that used to have their servers bring diners piles of empty plates, now require diners to get their own clean plates one at a time; and much smaller dessert plates are stacked on the dessert bar. I'm sure both of these are intended as cost-saving measures, but the health benefits of eating less are still there.
