I think this is very interesting.
And I think OA and WW have a lot in common in terms of the actual concepts. The only thing is that I wish WW incorporated more about emotional process into the meetings. Like have everyone talk in detail about a trigger moment and how they chose to get through it. For me, it's become as simple (and as hard) as learning how to say "I am not hungry. I am MAD." or sad or whatever. Usually mad or sad are my triggers but it is a LOT EASIER to understand and see them coming and then choose to do something else.
