The thing about the 'soup, salad, cereal' diet is that there is so much variation among different soups, salads and cereals.

To me, a salad is chopped up lettuce and vegetables. It's low in calories because it's high in water. (If you add tofu, cheese, or hard-cooked eggs, it's not just a salad anymore.)

Soup can be thick, rich and full of protein and starch, or it can be thin and watery. The more watery, the lower in calories.

A bowl of cereal also contains a lot of water, whether it's cooked in (oatmeal) or in milk (Cheerios.)

I think Crow Sister's diet should be called The Water Diet.
