I thought it a good book, quite funny, and although the food he eats is way above us mere mortals who do not fequent restaraunts or live a jet set life, the principles he uses in the diet are available to us all, in fact he does not really know how he has lose the weight!, the simple reason is that unknowingly he has been on a so called new diet called the calorie shifting diet whereby you trick the body into not knowing what amount calories are coming from day today, or what type of food source either protein,Carbs etc, the body mintains it metabolisum and burns fat,a simular thing happend to stone age man and they did'nt know what was happening either.
If you study what he eats its all mixed up Carbs, protein, calories diffent each day, to use this diet with normal food, you simply shop for differnt types of heathy food you love and eat smaller portions,I've been doing it for a while and have lost loads but I eat realy well, swap what Michael eats for thing of simular type, but not of course costing as much!
Give it a go, at least you will be happy and well fed giving it a go.
