I think that sometimes people have a psychological issue with certain meals. Like, if there isn’t a blob of meat on their plate, then it doesn’t really “count” and they’re entitled to a REAL dinner goddammit. This feeling of “If it doesn’t include a protein, then I’m not gonna be happy” of course has nothing to do with the volume or the caloric content of the food consumed.
Of course, knowing that you have to compare “apples to apples”, (sorry for the food metaphor which seems to confuse matters more than necessary!) is important. If you compare the satiety of a chicken and cheese burrito, up against the satiety of a no-oil brown-rice-n-veggies burrito OF EQUAL CALORIC VALUE — then I highly doubt if you’d be telling me that the first burrito fills you up better and lasts you longer. The first one is pretty much absent of any water or fiber, and takes up little volume in your stomach (or on your plate) while the second is hella full of water and fiber, and takes up a crap ton of volume in your stomach.
Then again, if you were to eat a whole foods diet with no added oil, and be “hungry” in an hour (psychologically, because there’s no way you’re passing out from weakness after a big brown-rice-n-veggies burrito!), you could probably eat a potato or a piece of fruit, and STILL your heart would be in better shape, than if you were to stuff chicken breasts and olive oil down your piehole.
Of course, if you are interested in getting the benefits of this way of eating, you’ll do great and figure out some awesome meals for yourself. If you’re looking for a way out, you honestly don’t need a reason — you can just do your own thing and follow your own heart. Both ways are available to you!
