People who claim that they can eat as much as they want (of protein
and fat, for example) and lose weight as long as they avoid certain
kinds of foods (carbohydrates, for example) are really eating less
(that is, fewer calories) than they did before.

Yes, they can "eat as much as they want". However, the absence of
concentrated carbs sending their insulin and appetite signals out of whack
means that "as much as they want", is far less than they used to want.

But what about a majority of people concerned about weight control who
are not interested in cutting out breads, cereals, grapes, bananas,
watermelon, carrots, beets, potatoes, rice and pasta (not to mention
wine, beer, cakes, cookies, ice cream and other carbohydrate-rich
foods banned on Atkins-style diets)? Are they doomed to remaining
hopelessly overweight?

No, they'll still have to practice portion control, only it will be
something they have to do very consciously, and contrary to what their
appetite is saying to them. The difference for the LCer is that it's less
difficult. Seldom does (IME) a low-carber need to force themselves to stop
eating.
