And make sure you eat plenty of fats, fat makes you feel full up pretty quickly. Full fat cheeses, a scoop of full fat yoghurt, unsweetened if you can bear the tartness. I also have a tub of full cream in the fridge and if I am craving food, some spoonfuls of this will do the trick. I also have a mug of unsweetened cocoa with full cream milk mid afternoon, the cocoa, especially if it is organic has serotonin in it to give you a lift and also cuts the hunger completely.
good luck, keep it up, it's worth it.
cheers
