A different methodologic approach to "ideal weight": a study of the ponderal index (PI)

It is clear from the literature that practically all of the evidence for "desirable" weight has been derived from mortality and morbidity studies. As far as we can determine this is the only attempt to establish "ideal" weight in terms of health rather than some measure of disease. There are two notable findings. First, "ideal" weight as judged by the ponderal index probably exists in a narrow range. Second, "ideal" weight as judged by this height: weight ratio is different in the sexes.
