Yes it works. When I restarted WW I as shocked at how many points I got. I did Core last time which workd for me until I was cheating more than I was on plan. I had a lot of trouble eating enough points at first...then I rethought my food choices and found it easier and easier. It does work. It's kind of like this...
A full size SUV needs more gas than a sub compact because the SUV has a bigger tank and a bigger engine. In order for it to go as far as it can...it needs more fuel. Our bodies are the same. The myth of 1000 calories a day being the miracle cure to being overweight...is a MYTH. If you don't feed your body properly (enough calories per day) it will think it is being starved to death and it will not let you lose weight. You will lose at first but then you will stop and that will be that. It has been medically tested. You also have to remember that for every 10 lbs you lose from your starting weight, you get 1 less point per day.
My best advice is track your food and be honest. Eat your points, use your flex points when you need them and drink lots of water. You really truly can eat what you want...but your body will get more out of more fruits and veggies, low fat and fat free dairy, whole grains and lean protein. But when you absolutely have to have that candy bar...you have the points to indulge now and then.
What has saved me and made my program easier is that my WW leader focuses on alternative foods...close substitutions for the food we love that are hgher in points. Sometims you just have to be a littel creative and do some research. There are also great web resources out there that provide similar information.
Good luck...I'm happy to answer any other Q's
