WW keeps changing their model when the original one worked best. 0 point foods (aside from leafy green vegetables) eventually translates into 0 calories in people's minds and there is no such thing. The new plan is particularly ineffective for this who follow a plat based diet. Beans, legumes, etc are very carbohydrate and calorie dense. Allowing this to be a zero point food is not the same as meat products.
0 points also leads to over consumption of the foods in this category and underconsumption of foods that are healthy because they come with a high point price tag.
The program has gone down hill. I've tried it a number of times after each change and it's never been as effective as the original format. This last go - I lost no weight at all. If you are plant based and over 50, use my fitness pal. Track your calories make sure you hit your macros to ensure a healthy balance of foods. You and your bank account will be glad you did.
