Now this is an interesting study although I'm not so sure that I agree with the conclusion fully.
Yes the portion sizes are important for status but not just that. Companies find that giving more for the same price is a good signalling mechanism to get more customers. That's not driven by status but the human tendency to like bargains.
Still one to think about for myself. Smaller portions with more control over junk food and more exercise!

“It seems to me that our three basic needs, for food and security and love, are so mixed and mingled and entwined that we cannot straightly think of one without the others.”
- M.F.K. Fisher
Human beings are notoriously terrible at knowing when we’re no longer hungry. Instead of listening to our stomach – a very stretchy container – we rely on all sorts of external cues, from the circumference of the dinner plate to the dining habits of those around us. If the serving size is twice as large (and American serving sizes have grown 40 percent in the last 25 years), we’ll still polish it off. And then we’ll go have dessert.
Consider a clever study done by Brian Wansink, a professor of marketing at Cornell. He used a bottomless bowl of soup – there was a secret tube that kept on refilling the bowl with soup from below – to demonstrate that how much people eat is largely dependent on how much you give them. The group with the bottomless bowl ended up consuming nearly 70 percent more than the group with normal bowls. What’s worse, nobody even noticed that they’d just slurped far more soup than normal.
