To add, @TurquoiseOwl, one aspect of losing weight is definitely coming to terms with the emotional side, and that is huge. So, forgiving yourself for any missed opportunities, being kind to yourself and reconciling your childhood with now.
I know it sounds grand but that was massively important to me - both thanking myself for starting to reverse my weight gain, and learning that I had to stop being an emotional eater. It was only once I did that I was able to start seeing food just as food rather than as 'naughty' or 'good', or a reward.
