He discusses the now familiar hypothesis that obesity may be accompanied by an excessive number of adipocytes, possibly brought about by excess feeding in infancy and childhood, and that the excessive number of adipocytes remains constant and in some way causes a drive for maintaining the obese state. He points out a critical methodological problem in that only
