from what i've learnt about randy he is older, a legit senior citizen i think, and started eating raw relatively recently in his life, and claims it is helping him achieve the best results so far. he went blind a few years ago and still wrote and researched this massive book, and still trains champion BB'ers. he likes raw chicken alot (which i cannot stand).
as for the carb issue. i think if a person can tolerate it, or can heal to the point that carbs produce beneficial results, then yes they are necessary for peak performance, but not insane amounts. these guys advise carbs on refeed days and post-workout only, and keto the other meals. the amounts they eat seem enormous if you are not an intense athlete, but is not really crazy when you push yourself to that point.
when i exercise more & more, i will eat more starches, probably root vegs, probably baked because i can't think of an easier way to prepare them "raw". probably NOT grains or seeds, and definitely not refined carbs unless i learn otherwise. honey or white rice spikes the body quickly and that might be useful at times, but only if afterwards we can mitigate the damage.
for the average person, i think a ketogenic style diet with well-prepared wild vegetables and herbal plant medicine is long term sustainable.
