The 95% figure applies over all methods of weight loss, not just SW. The owners of SW know this figure, and as with most of the weight loss industry, rely on it to keep the money flowing. It is incredibly demoralising but it’s also a biological reality and we’d be far better off as a society working out how people are getting fat to start with, dropping the fat shaming, and investing in more mental health and nutritional support.
The key to maintaining weight loss is understanding why you are overweight, and working through that, and obviously maintaining a decent diet (which is easier to do once you’ve resolved what underlying issues you have). SW doesn’t facilitate any of that. Once you lose the weight, it’s up to you to work out how to maintain it.
It also doesn’t offer any really decent nutritional advice. On the face of it the plan sounds very sensible, based on cooking and eating fresh food and restricting treats. In reality the group leaders push all sorts of fake food that fits the SW principles. Food suddenly acquires Syns when commercial endorsements come to an end. For every person who gets to target weight and has changed their life completely to create sustainable weight maintenance, there are 99 who have been living off Muller Light and counting the days till they can go back to eat ‘normal’ food.
And as for watching the exercise... I couldn’t believe it when I first went to a group and heard someone getting warned off. That’s insane. Exercise builds health, drives faster metabolism, helps to prevent health conditions developing, and improves mental health and wellbeing.
