For me, in a way, it wasn't SW exactly that caused issues for me. It was group. And the weekly weigh.
To sit there in the group and to he singled out and asked why I gained weight that week did not help me in the slightest.
My consultant was even going to the point of asking people where they went wrong when they only lost 1/2 or 1lb that week.
Because then I was going to extreme lengths to not gain or to lose more than 1lb a week.
To be shamed for gaining or struggling. Even worse at the time, I'd just had a baby and my body was up and down constantly.
Myself personally during "Star week" (as they call it always made me laugh"

I'd gain 3 or 4lbs. And then within 5 days, it'd be gone.
But she kept telling me it wasn't possible and I was making excuses and basically laughed at me infront of the whole group.
It was a horrible experience!
Again. Not SWs fault because that's how they do things. But it is what caused it all for me
