WWers still has people weigh food . . . I weigh and measure food constantly
Those who tend to "eyeball" portions, tend to under-estimate how much they are eating.
One thing I can suggest for those on WWers and struggling, go visit their message boards! They really are great over there and using the message boards are free. I've learned a lot and gotten a lot of good tips from them.
I have PCOS/IR and have been losing successfully on WWers since September using every single Point available to me! It's not a quick loss by any means, but it is working.
