Can you do Weight Watchers without points?

Yes, but it could be difficult, since Weight Watchers teaches portion control.

On the new Points Plus plan you can do something similar to the "core plan" (used to be a UK WW plan) where you can eat (without counting points) from only the "powerfoods" list (i.e. the foods determined by WW to be most filling and healthy like veggies, whole grains, fat-free dairy, etc...) and you get 49points PER WEEK to use on stuff that ISN'T on the list.
