I didn’t see any evidence showing that it stops working if you have flavored fat. You say you’ve eaten fatty meals, but have you eaten fat-only meals, first thing in the morning? Most of the fatty things that people would normally eat are also high in protein, which has a very different effect on blood sugar.
Oops, there is a much better objection to your hypothesis which I should have made the first time.
Seth Roberts started out suggesting that people use either sugar water or flavorless oil to get their tasteless calories. Eventually he stopped recommending sugar water because of the negative effects on blood sugar levels. But not because it didn’t work!
If your hypothesis was right, then sugar water would make people gain weight, and there would be a dramatic difference between the sugar water and oil methods. Whereas my impression (although I didn’t read the forums thoroughly) is that people only found a small to moderate difference between sugar water and oil methods.
(And no, I have not tried a fat-only meal first thing in the morning, I always have protein with my fat, so you’re right that I don’t have a fair comparison)
