Weeklies should i or shouldnt i?

Hi all just signed up to ww online after many years of doing the old discover plan its hard for me to adjust .It says I should have all my weeklies pp but i cant imagine having all and having decent losses. Why are we given weekly points?. have any of you guys ate all of your weeklies and lost weight? How are the weight losses for eating just your daily pp?
Sorry for all the questions

I think it's trial and error with weeklies. Use them and see what happens, if you're not happy with your losses you can reduce them x

Weeklys are part of the plan,use them all then if you get stuck they can be reduced, the pp is not really any different from old plan,apart from the fruit, good luck x
