That's amusing on one level, but I do know that many struggle to create a caloric deficit, and some foods do seem to make it easier to feel full with less.

Definitely, and I feel like "some foods" varies per individual more than I hear people talk about.

That’s a very fair point, I had not considered that.

Nice. It’s still good to have these methods for achieving the ultimate goal, people just need to stop presenting whatever works for them as the one true way.

Yes, it is true that they have the same qualitative goal of creating a caloric deficit. However, some diet patterns slow down the metabolism more than others, which heavily impacts the likelihood of success in creating a significant (quantitative) caloric deficit
