Thought this was mindblowing. A lot of it was familiar to me (e.g. women need a certain level of body fat) and some of it I knew as urban legend (e.g. body fat set point theory).
However, he references studies and talks about things men might experience at 5% body fat that I never expected, like extremely low testosterone.
People aren’t meant to be at 5% body fat. It comes at no surprise that it’s unhealthy as fuck.
