To me, one of the attractions of the WOE is that it does let you be quite kind to yourself. It is easy when you are not happy with your body to slip into a sort of self punishment regime. Woo - I don't mean to psychoanalyse you! I couldn't do that for myself! But it does seem the only way to stay lean and healthy for the long run will be to make it pleasant and liveable.
So good luck to you, and I look forward to hearing you're enjoying keeping it simple.
