If you are hungry you are going to grab things you shouldn't in a hungry moment. There's nothing wrong with carbs - if you are following a body building diet then it needs to be high protein, but otherwise it won't do you any harm eating some carbs.
Try EE - it is a a lot more like "normal" eating. Stock up on some snacks that you can eat for free, not just fruit and veg sticks - I have a stash of pasta in a cup and mug shots in my desk for hungry moments, keep some Mullers in the fridge, as well as fruit to hand, or even a small tin of baked beans!
If you are hungry then you're not doing it right!
I always have a substantial breakfast - porridge alone wouldn't do it for me. I have 1/2 a tin of beans plus a 2 or 3 egg omelette with some mushrooms, tomatoes and spinach in it. Keeps me going till lunch!
