When I cook at home, cooking never causes me to eat less when the meal is ready, unless, of course I was taste testing more than usual. However, when I went to culinary school and saw how the food was prepared and knowing the food was not really health supporting; I rarely ate what was prepared in class.
I was more of a low-fat cook and the instructors would always come up behind me and pour in the oil (often fake butter flavored stuff). I'd complain that they just ruined my dish and they would laugh.
I got the last laugh though, I lost 25 pounds while attending and I am not sure how much they gained. Sad, isn't it.
