This. My mother lost 100lb on weight watchers, and the whole "fruits and veggies are free, high sugar cost more than calorie value" thing got her used to the idea of making better choices and turning it from a diet to a lifestyle. She's been a stable 140 now for 10 years, and while not on the plan anymore those lessons stuck with her past menopause and helped. It's not a scam, but an education tool for those stuck in fatlogic.  Then again, some idiots will still fail as once they lose weight they go back to eating like a fucking pig. Ugh.
