I think the book is bogus...simply becuse there are more factors to all of what you described other than blood type. Such as Test levels and Thyroid output.
I have a buddy who is blood type O and so is my wife...both tire very easily, and can put on fat in a heartbeat...the wife uses starbation to keep her weight down...she only eats like once per day. But hell she looks good.
I am Type A, I can put on fat in a heartbeat, and am slow to put on muscle (t-levels and Thy-levels are low) But I do have plenty of energy, endurance is great on my "second wind" but I burn fat super slow.
I think it is totally dependant on a persons whole body chemistry...not just blood type.
