Hi I'm lisa and am planning to join SW next week. It's a bit early to post on here I know but I thought I would introduce myself. I have 9st to lose but physical problems. Copd which is a lung problem. And find it difficult to exercise. I was on Exante diet which is just milkshakes same as the cambridge diet but I was just so hungry. But I'm worried about joining SW as I can't do a lot of exercise. Will it stop me losing weight? Thanks x
