This blog was a great idea and I've really gotten some mileage out of it -- but what makes Loseit.com so much more effective is that it gives you feedback. It tells you when you're screwing up and perhaps more importantly when you're on the right track.
And I'm not just saying this because I've lost 13 pounds since starting on it.
I'm starting to think that when it comes to breaking habits and really forcing change on myself, I have to find ways to kind of obsess over it. Lose It (at least so far) offers me a lot of different angles to approach things -- so as a result (added to the fact that I have my son a lot more lately [don't ask] and therefore can't focus on other things so much) I've gotten pretty into learning as much as I can about it.
I'm also making big changes on what I eat, and how I think about eating. Slow progress on that sort of mindset change -- but at least the pounds are dropping.
