So bloggers from "both sides" are looking at the NIH study which "proves" that caloric restriction does not prolong life in the rhesus monkey. ...I don't think the proof is quite final.
I'm inclined to side with Dr. Rosedale upon learning that the poor things were eating a low-cal diet all their lives, which was 60% carbohydrate. Imagine how hungry they must have been! I think that the depression that you see in human beings eating like this should be factored into the mortality rates. Anybody but me ever read "When the Body Says No"?
Imagine eating 30% below normal intake of calories through your growth spurts and reproductive years. Then think about 60% of the calories you ARE allowed to eat, being things that will spike blood-sugar ... and the low-sugar "hungries" that follow. I think that's just plain cruel.
