Low cal foods??

I know some might think its sad to ask this question cause everyone should love themselves- lalaa...
But iam going on holiday to spain in July, so needless to say, I probably wont be wearing clothes that ofen and would like to shape up in the next...

couple of months.

SO I was wondering if there are any specific low cal foods I could use to replace what I would normally snack on (toast, chocolate, crisps etc)

Thanks !X
