I've said this very same thing for years!
it's so easy to overeat vegetables.
with protein, your body tells you when you've had enough and you can't take another bite, but when it's vegetables, a little salt and butter makes them so good that you can end up eating a whole head of cabbage or cauliflower...

ZIOH is not a good example of eating healthy with 0 carbs.
the man in charge, changes the "description" to fit his needs on any given month.... If I recall, ice cream was introduced in 2007-2009....
He's not a good barometer for learning the best way to eat 0 carbs.....
