WW points don't translate well directly into calories, because it's not like there is an exact 1 point = x calories guideline. (There are estimates, certainly, but nothing is exact since points take into account fat and fiber.) Both ways of tracking your intake have their strong points and their weaknesses, but the major thing they have in common is that you have immense flexibility in what you can eat (nothing is off-limits). The new WW plan encourages you to choose from fruits, vegetables, and whole grain options and actually eat healthfully in addition to eating less, but it remains just a guideline. Still, many of us on this new program are finding that even the existence of such a guideline is proving to be immensely helpful.
Anyway, not sure if that's what you were looking for - but that's a little of what I think
