...I was going to mention this a while back. Was reading this during the summer when I was overseas and felt it was worth bringing up here.

Not a
brilliant book, in fact to be honest I would rank it as 'okay', definitely a light read but with some funny moments. What intrigued me is that it seems to have been sparked by the author's interest in properly researching the subject (he's a big guy who used to be quite slender, which is shared by the main protagonist) and incorporating a lot of contradicting arguments into the dialogue. There's a bibliography at the end which, I imagine, is where he got a lot of his information (the story is fictional, although it's technically three stories which are loosely interwoven).
Not sure if it's available outside the UK but may be of mild interest. It might be worth just posting the bibliography...
