Hi, don't worry. Iv been at slimming world now for nearly 2 years. Some people don't lose much in their first week, often the second week it will happen. And remember, half a pound a week is nearly 2st in a year! A loss is always better than a gain. I understand your frustration but stick at it, I'm 2st lighter and my journey wasn't an easy one, but you only get out what you put in. Good luck and keep at it.
