There's more to it -- there's a considerable delay between your stomach being full to your brain telling you you're full.
I can eat one pound of icecream in one go before I feel that I'm done, or 1/3 of that, tell myself I can eat the rest in 15 minutes IF I still feel the need to at that future time, and I usually don't -- sort of like the reverse of telling myself I'll only work 5 minutes on that boring task I don't want to, but usually I work through it all.
My unscientific point being, there's no way the brain can tell I've eaten 1/3 meat and 2/3 salad vs 3/3 meat in the span of 15 minutes; sure, it will digest the salad much faster, but by that time I'm already doing other things that don't involve me stuffing my face with food; I've found that with food, if you can resist the urge to eat more for 15 minutes, and don't have snacks just laying around you, you actually solved 90% of your overeating problem. SO in my experience, eating broccoli/salad, or just drinking water, absolutely do work to make you full/less hungry, for a short while at least, but that short duration should not be underestimated, because a lot of times is all that is required for one to stick to a caloric limit.

Again, I think this is trusting too much in "today's science". Who's to say that your body/brain can't detect whether a food is nutritious? For all we know, some trace nutrients are subconsciously detectable in taste and smell, even if heuristically.
I'm not saying that is what happens, but I don't think we know nearly enough to dismiss such a possibility.
