You can do a Special K diet where you eat a bowl for breakfast, another for lunch and then a balanced meal for dinner.

11 Group 1: Special K is not as good for you as plain old cornflakes it has 4g more sugar per serving But porridge is best to provide you with energy and fibre for the whole morning Porridge is also miles cheaper!
