Disagree , protein and fiber is best for satiety. You have to limit fat including saturated versions of it to stay healthy and control cholesterol

I can eat unlimited eggs and never feel full (hyperbole, but getting my point). 150g of fat plus a salad with lettuce, tomato and cottage cheese makes me full, which is something hard to achieve for me

Same amount (weight? volume?) or same calories?

A low fat salad will fill you up longer than either of those options due to the larger volume in my experience.

It will fill your stomach but it won't stick with you the way it would if you had some fat.

That's complete nonsense if you are TRULY hungry. If a salad fills you up, you have psychological hunger, not a real energy need.

I have been in a situation where I accepted very light super (even though I run every day), in particular salads and invariably I have been awoken at night hungry as hell.

Real hunger is satisfied with calories (and your ability to process them) not the volume they have.
