Do you want something crunchy, or something smooth and melty and soothing?
Cos according to Linda Spangle, another 'any diet will work, you just have to know how to make it' guru (can't believe I'd never heard of her either), if you want something crunchy, you've got 'head hunger' and you're probably angry with someone or something and want to psychologically 'crunch' them up.
If on the other hand you're drawn towards smooth and soothing, you've got 'heart hunger' and it's more likely to be due to you feeling lonely, bored or unhappy...
