I agree with each of these posts. I have started to focus on NOT over-eating, and I am not a big water fan so if I find myself in the kitchen staring into the fridge or cupboards I drink some diet coke. That way I am putting something into my stomach without the calories but which is yummy! Also I am very fussy on what I buy on shopping day now. I am resisting buying all the snacks and 'quick-fixes' that I would normally buy and instead have upped the fruit that I buy. But as I said I think the biggest thing for me is having that glass of diet coke when I start thinking of/searching for food.
Good luck with this.
