It makes the dog feel like he's eating more than he actually is. The dog is eating a big kibble that has a hole in it. Because it's a big kibble, it takes him longer to chew it, and therefore longer to eat the bowl full. Just like in people, if you eat slow, you become full on a lot less food. They recommend that for people who are dieting.
I guess it's kind of like if you had a really big donut in front of you with a big hole and a small donut in front of you with a small hole, your eyes would tell you that the big donut is a better deal, but in actuallty they are the same mass. You would also feel fuller on the big donut with the big hole because it took you longer to eat it.

As I mentioned, I used to be a demonstrator rep for Royal Canin. There sight doesn't say anything about the kibble with the hole in it, but if you ask a RC rep, that will be their explaination.
