Hi. I'm a WW and weight-loss newbie since this is the only time I've really dieted with any focus. I've lost 4 stone 11 lbs since September. I've got 20 lbs to go but it's now coming off really slowly; only 1/2 a pound week for the last three weeks. Can I expect this to be my pattern now or is this just a blip? According to the website, I should be losing between 1 and 3 pounds per week. Please help keep me motivated!
