An adjective used to describe something that is relevant to healthy bioenergetic practices. Originates from the biologist Ray Peat who founded bioenergetics.
Platygaean is a fancy word for a Flat Earther. Platygaeanism was a fringe interest until the 2010s, when it suddenly started getting massive amounts of media coverage and funding. Which was highly convenient as the Flat Earth meme is useful for damning any alternative thought by association. Platygaean sounds far more sophisticated than "Flat Earther", so next time anyone calls you one for thinking for yourself, tell them they're not using the proper term.
