This surprises me too.

Per calorie, water is very good at making me feel full immediately following ingestion, and I remember seeing evidence (as well as personal experience) saying that fats are especially bad at this. However, feeling satiated hours later is different and I'd expect it to reverse. The part that is really surprising is the equal or lower subsequent food intake with carbs. I'm not sure what happens when you use nasty fats like transfats or oils high in omega 6, so as far as I know, maybe they were using different fats that are less satiating than carbs which are less satiating than animal fats?

I want to check the references, but I don't see where he says what "(4,5,6,7)" actually refers to.
