i would like to point out that you can get fat even when not eating junk.
i go down the lolly isle simple because the other side is the cereal.. so i have to..
i know i dont buy chips or sweet bisuits or lollies.. i have started to buy 1 block of 85% chocolate every fortnight(i shop weekly) as i dont and cant scoff a whole block.

i definatley agree with looking at why you are eating and if it due to emotional issues or a reactive type responce.
