I have been a WW off and on for years. It is the only diet/lifestyle change that seems to work for me. I like to cook so I have trouble with most other diets. I lost about 20 pounds a couple of years ago and it has stayed off. I go up and down a little but have kept it off. I had about 110 pounds to lose total. I am currently flowing program and am down 40 pounds. I can eat whatever I want. If I know I am not allowed to have something I will crave it. I like WW because nothing is off limits. Just knowing I can eat certain things if I want helps to keep the cravings down. I have to pay for it with points but I can have it. I have pretty much cleaned up my eating and it really works for me.
Good luck on your journey and healthy eating.
