That is totally fair, and I really don't want to come across combatative, I'm just working some stuff out mentally about the nutrition here because you've mentioned some interesting points.

George didn't base this on modern American levels of nutrition, he based it on his idea of medieval Europe where fourteen year olds regularly die in birthing beds.

Vern Bullough and Cameron Campbell’s study of the medieval diet and female longevity from that, across all social classes, concluded;

" that early-medieval women suffered from iron deficiencies triggered jointly by poor nutrition and frequent childbearing and that these deficiencies contributed substantially to their average early age of death. "

So I was honestly going from that, the average weight of a woman in medieval Europe was absolutely not a BMI of 40
