Keeping a record of what you eat and your emotions at the time can be a helpful thing, if your eating is influenced by moods. Keeping a journal is a good thing period. :>

Once can only do their best. And if it's your best, then it's right.

I'm not the sharpest tool in the shed, but a hypothesis? When eating normally like you would in a day, do you differ very much? Like same calories and generally same food and excersize? Differences to your routine can jump-start weightloss. Positive thinking can too. ^_^ Not dwelling on things too, what's your secret?
