When I met my other half he was an informal follower of this approach to eating. Over time I've also started eating like this and it seems to be suiting me.
My mum was over for Xmas and it turns out she used to do this and had a great book that both gave the details of how to do it and some of the history/science behind it. She can't find the book or remember the title and author.
So I'm thinking I bet there's someone on mumsnet that will be able to help so that I can find a copy on eBay or amazon!
Thanks in advance...
