I've been doing SW since Jan, and have lost 1st 4.5lbs, 3.5lbs to my target weight, which I set myself, there is no ideal weight on the SW plan, you set it yourself, what you think you'll be happy/comfortable with.
For what it's worth, I don't eat or buy processed food I've never eaten a SW meal, SW soup or used any of their ready made sauces. I cook every meal from scratch, use my slow cooker a lot, make 'free' soups and freeze, eat loads of fruit, veg, eggs, and plain yoghurt. I don't eat muller lights, I prefer Danone fat free yoghurts. I do like pasta, potatoes rice etc, but not in enormous portions.I do have the occasional hi fi bar. I'm not someone who craves chocolate or sweet things, so tend to use my syns on more savoury stuff like cheese and crackers. I'm not sure what's unhealthy about my diet. I certainly feel better than I did.
My leader is lovely, she's doesn't spout on about muller lights, she talks about fitting the plan into your life more, about forward thinking, planning meals for the week etc. No pushing hi fi bars, they're at the back of the room if you want them. She's pretty 'real' actually.
No body shaming goes on, your weight is kept private. Not announced to the room. So not sure why people are saying that.
I get that it doesn't work for everyone, and some of you think it's crap, but I think you get out of life what you put in. If your not willing to work at healthy eating/dieting/whatever plan you choose to follow, it's not going to have any effect. There's no magic pill you can take, it comes down to calories in are less than calories used.
