I know you might want to do this solo, but having people help you (especially if you are like me and need support) theres a thread about this kind of thing that you can join. It really makes you think about what you eat when you have to post these things for other people to see. It might also be nice for your friends at work to see how other people with different goals manage to handle it.
Anyways, take it or leave it, the link to the current thread is down below:
