That's a lot of very useful information, thank you for posting that!

I did want to ask if you could give a brief run-down on the different types of fat and which ones are very good and very bad for you? I always get confused about the whole transunsaturated/polysaturated etc.

Have a tip on carbohydrates:
Make your carbs work harder for longer - choose foods that have a low glycemic index as it means that your body takes longer to use it up as fuel for you, and you remain fuller for longer, so it reduces the craving for in-between snacks. Brown or wholemeal bread, raw sugar or honey, things that aren't processed to death and high in sugar.

My favourite low GI breakfast is Kellogg's Special K with soy milk.
