I admit that I've never used slimming world and have based my opinion on hearing other people's experience.
However, these groups aren't really set up on the best interests of the people that use them.
For example, calling food syns, that sounds like sin. Of course over time subconsciously you will look at food as 'bad'.The weekly weigh-ins, under the pretence of group support, however causes self-consciousness and shame if they did not loose weight that week. At that point they put pressure on themselves which usually backfires, they give up. When in fact, after the initial quick weightloss, it slows down or remains static.
It's ridiculous if the advice given out depends on the consultants interpretation- otherwise you gey advice like a previous poster saying that the only yogurt you can eat is low-fat. There's so much research and evidence now that proves that eating whole fat foods actually keeps you full for longer and is better for you.
I'm not just against slimming world, this is also for all fad diets, including all the protein bars/shakes aimed at the fitness industry. All these products and diet advice/books/groups are a huge money making business.
We all know that we need to eat food in its natural state. However, the food we choose or can afford to eat is a small part of the problem.
The bigger problem is outside our control: genetics, age, life stressors, socioeconomic factors, the quality of food that you can afford & is available to you & the time you actually have to make your own food.
There's a reason why you have more fast food, junk food, sweet shops in deprives areas. It's not a surprise that people in poverty have crap diets, they simply cannot afford healthy food. As a treat its going to be mcdonalds, not miller&carter.
