I've been on SW for 13 weeks and love it. Lost 1 1/2 stone, want to lose another 3. Our leader is fantastic, she has an encyclopaedic knowledge of products and where they are or aren't in stock across about a 20 mile radius and 6 supermarket brands. She also does cooking from scratch, recipes, ideas to try etc. The balance is about equal between clean type ideas and processed stuff.
There's no "ooh boo I'm struggling too" from her, she used to be size 22 and now she's a size 8 and wears tight dresses - it cheers me up just to look at her! But every so often she'll let out how she had a sore throat and ate 8 muller lights in 3 hours... she understands compulsive eating, has mostly conquered it, and knows how to lose the weight and keep it off. We can NEVER get her to say "it's not fair, it should have worked, you should have lost weight but you didn't" - she's firmly convinced that if you do the right things, the diet will work.
SW is a DIET!!! I know they don't call it that because the word is out of fashion but it's a way of eating to help you lose weight. If you do it right, it works. Doing it right is sometimes more complicated than it would first appear.
They have simplified the plan as much as possible but underlying it are complicated calculations and averages and sometimes one thing falls on the Free side of the line (whole banana) and the other falls on the Syns side (mashed banana).
Anything you could potentially have vast amounts of needs to be synned. If mashed banana was free loads of people would have daily smoothies containing 10 of them which is tonnes of sugar. Whole banana is free, does anyone eat 10 a day? 3 a day is probably the maximum.
Someone upthread said they didn't want Overeaters Anonymous but that's exactly what I needed. I have tried, lost half a stone, and celebrated with food (so the weight goes straight back on) and new clothes that I could then never fit into about 10 times in the last 20 years, and I need to sit in a room full of other people who struggle with their weight and say "I'm Sticky and I am too fat and this week I tried quite hard but still ate cake and therefore I didn't lose any weight." OR - "I lost weight this week because I went for 3 runs and ate mullerlights instead of muffins".
Enough about me :) OP I'd recommend you try more groups until you find a good one, either one with a good leader or one with good people.
