i saw this book at costco. it does suggest eating good things like peanut butter, raw almods, blueberries, green tea, whole wet grains...stuff robert and everyone else suggests regularly. but it's big on egg whites and whey protein. that's where most of the protein comes from.
i stopped looking at it after that. it seemed to preach mostly high intensity abs workouts. lots of the routine looked like mat pilates to me. but that is because i do mat pilates for abs.
but, yes. the diet was pesco vegetarian. i think it said to eat salmon and white fish. but the whey and egg whites seemed crucial.
