I have been through the Weight Watchers online program and it was great. It sounds like it would be a good fit for you too. I got to my target weight and I have managed to maintain my weight for several years now. Weight Watchers helped me identify my bad eating habits and replace them with better, healthier food choices. I live in Canada so I used Weight Watchers Canada online but I hear that the US men's Weight Watchers online program is amazing (lots of exercise tips and more). (I wish we had that here in Canada). To answer your question, no you do not go to meetings when you are enrolled in the online program.
You have chosen a great time of year to start with Weight Watchers because we are just entering what they call "weight loss season" and they have some great offers/discounts for the online program. Both in the US and Canada you can get the sign-up fee waived or get a discount.
