Just picked up Dr. John Briffa's latest book, Escape the Diet Trap, in a charity shop, for £1.99 (RRP. £12.99.) LMFAO!
It seems to be a pretty good book. I think it would be a great introduction to paleo/primal diet (lifestyle) for your standard SAD-sack. It covers the basics of the science for adopting Primal and leaving SAD in a few very short chapters/pages; of course, with linked research reference and... That's as far as I've got. It shouldn't take too long to read; it's so user friendly. Escape the Diet Trap: Amazon.co.uk: Dr. John Briffa: Books
All the best!
