I never really did "portion control" -- my sister did. She did calorie restriction, and portioned out everything that she ate. And, she did really well on it -- so long as she continued to do that. Which she didn't, so she gained everything back and is at her largest currently. Maybe second largest.
For myself, I tend not to over eat these things unless I'm stress eating.
Currently, I don't have pizza (pizza in this country is terrible), but I will have cookies on occasion. I usually go for raw ones, which are paleo in their ingredients. And I usually can't have many because they are so dense and filling.
