Well you can eat anything on SW too BUT I find this works for me. I have done WW in the past and I didn't like counting points at all... I need the freedom to be able to pick something up and eat it without worrying how many points I have left for the day.
Ok so SW has syns but I know that if I want to save my syns I can go eat a packet of chicken or carrots or a muller light and they are all free... real food, filling food and it is free! I can drink wine, have gravy or mayo, I can eat out and as long as I count my syns (which I don't mind doing at all!) then I can still stick to plan!
You also really need to want to lose weight for yourself... if it's for someone else then your heart and mind might not be in it. We all want to look good and have people compliment us but sometimes the bigger picture is so much more of a motivation. For example I know that if I hadn't started SW I would have gained and gained... I needed to act now whilst I still thought it was possible. I don't want to be a 'fat' mum, I don't want to not be able to chase my little boy about, I don't want to put myself at an increased risk of heart disease, diabeties or cancer. I want to be healthy.
We all have times when we struggle but I've found this site really helps. More often than not someone else has posted what I wanted to say and the responses they get just click with me.
