So how are you doing it?
I'm counting Weight Watchers points. I joined a few years ago, so I have all the books (old system) so I just using that and I finally found a good iPhone app that counts points without joining WW. It's called "My Score Plus" and it is the best I have found for me (and I have downloaded quite a few). I did realize the other day that my app had miscalculated the number of points I should be allowed to have a day - I thought the number was high. Then I looked it up and sure enough the app was giving me 5 more points per day that I should be allowed. So I adjusted that on the app. Hopefully that is one of the reasons that I haven't been very successful.
So, I'd love to hear from you in the comments. How are you approaching your weight loss? Are you counting points? Calories? something else? Let us know!
