It was a full page ad with a picture of a man at 18 stone and then 13 stone - quite eye-catching in itself as it made a change from the usual female before and after shots associated with diet stuff. He put it all down to a diet book he purchased online that was "revolutionary". Usual, evangelical diet-speak - basically making out that after reading the book you would have very little excuse not to lose weight. Coupon attached to order the book - the title of which was obscured to add to the intrigue. Wondering if anyone knows any more about it or has any theories on what mysterious secrets it may contain?
