I'm sure there's good scientific reasoning behind this, and the diets tracked are probably very different to mine, but this strikes me as incredibly counterintuitive. Personally, I find potatoes a good way to keep my calories down (as a lowish calorie starch that keeps me fuller for longer), I avoid nuts as I don't find them at all satiating (and they're incredibly high calorie density), and cheese always spikes my calorie intake (even if I'm using it to replace something else, I end up eating more on days I have cheese). (Side note- I just read the transcript, rather than the study)
Interesting, in any case.
