Hi everyone - I like to think of myself as an old pro, not because I have lost loads and kept it off, but because I've done SW 5 times and always lost and I know the plan pretty much inside out so I'm going to try and answer some of your questions.
Syns
Syns are everything that don't fit into the catagory of free food or healthy extra - it's not just "treats" like chocolate, wine, sweets, buscuits etc. although these do have a syn value. It can be things like gravy, butter, stuffing, additional Healthy Extra's like cheese, milk and bread.
PLEASE USE YOUR SYNS!
The reason peoples weight loss slows down, or they start to gain when the try not to have any is because the body isn't getting enough calories to function and goes into starvation mode and hold on to everything - what you've got and what you give it.
You need calories to burn calories. I know SW doesn't work in calories, so think of food as energy, you need energy to burn energy.
Soceity at large has been giving you mis-information, it's not your fault, you need to forget everything you've been told before about loosing weight. The first rule of Slimming World is everything in moderation, this is a learning curve and that is why free foods are free - eat them until you feel full and stop.
Most diets fail because it's impossible to keep doing them forever, the deprivation of food groups or lack of nutrients. Three basic things to remember with Slimming World: free foods - they are there so you can eat and feel full, carbohydrates fill you up and slowly release energy and protein stops hunger pangs and makes you feel fuller longer. Healthy extras are there so you get all the vitamins and minerals your body needs, but when these foods are eaten in excess you gain weight. Syns are there so you don't feel deprived and have a balanced diet. The reason an item has a syn value is that they have a lower calorie density than free food and if you eat too much you gain weight - that is why there is a set amount.
Hopefully that will answer some questions and help you get your head around it better.
All the best, and good luck
