Hi Emma, welcome! Good to see you here. My pennyworth would be... Relax, what you are doing foodwise, sounds good, but there are a couple of small things that perhaps you should check....1) the sweetner (must be Splenda) apparently, the other sorts can sometimes cause problems with weight loss.
2) The beef stock..I know the sort I have at home (powdered that you mix with water) is quite high in carbs, so much so that I don't use it at all, and 3)Do you put lots of onions in your chilli, cos they are very high in carbs too... apart from that.........like everone says, DRINK THE WATER. But hey, look, it's early days for you, hang in there....it will happen. When you've got time, start a journal, and we can all pop in and see how you're doing, and help you along.
