Unfortunately no mention of prices, so increase in portion sizes might be below inflation; and I suspect the former could be a strategy of compensation for inflation by making it seem less drastic ("yes it costs more, but we also made it bigger!")

The cost of labor has gone up faster than the cost of food ingredients so portion size inflation is a rational response by restaurants.

One time when I was a kid and my dad and I were in line at Fuddruckers, we overhead someone else in line say "I don't think I could eat a third of a pound, so I'll have to get a half a pound instead. It's still a reference we laugh about over two decades later.
