To be charitable to the GP, you could imagine that physical indicators that correlated/anticorrelated with success in the ancestral environment no longer did today, such that if you were picking between the 6'5 and 4'2 guys, the 4'2 guy has a highler likelihood of being a tech millionaire/programmer and resistant to microplastic-based infertility, and thus can provide/reproduce better than the 6'5 guy. I.e. the average woman's attractions aren't calibrated to the modern environment, much how most other instincts aren't calibrated to the modern environment.
So, over time, the rare woman who prefers short obese kings would outcompete the rest. I don't think this particular example is the case, but I do think something like this dynamic is happening.
(In the other direction, actually.)
