Testosterone is directly causally inverse to bodyfat in men (once above some very low baseline)

Fat directly converts testosterone to Estrogen via a process called aromatization.

Personally my Testosterone close to doubled when going from 25% bodyfat to 13%. I get blood tests regularly and can see the levels fluctuate pretty closely with fat levels

My takeaway from this is that obesity... is the cure for baldness? xd

Baldness is caused by dht

Which is a byproduct of testosterone, so...

Even if more testosterone means more DHT, most of the variability in hair loss is explained by differences in DHT sensitivity levels.

It would explain why fat people are more often than not bald anyway and why Styropyro has the most hair I've ever seen on a person regardless of his condition.

In the past decade, research suggests that testosterone levels have actually gone up[1].

Really makes the study completely pointless when the last 50 years has also seen the rise of the global obesity epidemic.
