I'm exactly the same when I think I've done well and then I don't see any progress. In the past I've also made the classic mistake of weighing myself more than once a week then I get downhearted and go off the rails as I think what's the point. A friend has suggested measuring too as sometimes weight doesn't come off but perhaps 1/2 an inch does so I might give that a go - I haven't done that in the past as I haven't wanted to see what the tape measure says! I need to change my mindset too, although I bought a book about doing that about 6 months ago and it's still sitting unread on my desk at work ;-) I've also realised it's all about planning meals as much as possible rather than just winging it. It will take a long while to shift it, but shift it I'm determined to do, and it has to be a lifestyle change so that it stays off. I'm really hoping that everyone else's journey will help and inspire me to be successful with mine.
