You might consider getting the electronic version of the Fast 80 by Michael Mosley? I'm a big fan of intermittent fasting, specifically only eating between certain times. He's the author of the 5:2 diet but this includes a lot of new material related to other concepts. I have a couple of friends on it who have lost 4 kg in 2 weeks and one has now lost nearly 8 kg in less than 4 weeks. That's better than I achieved on a 5 day fast (which I did purely for interest). It has recipes and doesn't really include full-on fasting as even at it's toughest you're eating 800 calories of pretty tasty food. Anyway, from someone who's gone from 103 kg to 85 kg (still obese) it might help. I'm planning to embark on a variation of it shortly. Still reading the book. It also helps answer some of those nagging questions dieters always have or are faced with.
