Yes, it's a good point! A similar data point is men of the Bodi tribe, normally quite skinny, have a contest to see who can get the fattest during a 6 month period: the technique the men use to get fat is to eat a lot of blood and milk. So dairy definitely has a lot of weight-gain potential, if you eat enough of it! (Though interestingly even the fattest Bodi men are still not as fat as the people you'd see any given day in, say, an American Walmart.)
