I wonder, though, how much is related to weight, and how much is related to good nutrition. It could be a nutrient that is missing that prevents
pregnancies in women, and reduces sperm production in men. This might explain why the superthin also have similar issues - they don't eat enough!
Perhaps the fat increases blood pressure enough that the delecate mechanisms that nurture babies and produce sperm can't operate. Could be that the
fat causes changes in hormones and body chemistry enough to prevent normal reproductive function.
Somewhere I've read that many pregnancies end before women even know they are pregnant as bodies know when something is wrong with the fetus and
expell it. Could it be something like overweight women are less likely to get something like folic acid in their diet, so they have a higher number of
defects, and a higher number of spontaneous abortions in the first few weeks before they even know they are pregnant?
It's a good example of "survival of the fittest" as you pointed out above. If bodies aren't in good shape health wise, their genes are least
likely to be passed on. Doesn't explain why America gets fatter and fatter - you'd think there would be some self-selection when so many people find
overweight people to be somewhat unattractive. Hmm...
