I agree with Slimdown, and I think there is a BIG difference in the WW points system and "just counting calories". The part of the points system that includes or counts fat and fiber is very important . . . and if you want to do even better for your health, read the book "Eat, Drink and Be Healthy" (Harvard Medical School/Walter Willett) and count the
kind of fats you are consuming.
I can't say enough good things about the WW plan, but I try to combine it with the nutrition information in the Willett book - I don't want to just lose weight . . . I want to be as healthy as I can get!
