Not really. Sure, if you're force-fed bacon and eggs, you might still gain weight, but the point is that fat uniquely "sates" us, and that they key word is "desire" -- you stop desiring more food.

In my experience, you can indeed eat as much protein and fat as you desire, and not gain weight, because you literally stop desiring to eat more, significantly before the point at which you would gain weight.

That's what's "special" about refined carbs -- you can keep wanting to eat slice after slice of pizza, day after day. Basically nobody can do that with fatty steak. Just try it, and you'll see what I mean.
