Correct.  There is a negative correlation between intelligence and obesity because low IQ results in high time preference.  High time preference means fatties would rather stuff their faces now than have a good sex life later. However, the mutation load hypothesis fails to explain fat high-IQ populations (SJWs, Koreans) and low-IQ populations being formerly very healthy (Australian hunter-gatherers).  To what degree is low IQ caused by mutation load as opposed to selective factors?
