Look how far they came when they had access to social supports and the high quality food we deny to the poor - it’s trying to shift the narrative from societal issues to personal responsibility… “look how easy it is - you too could lose hundreds of pounds if you got off your lazy ass” without regard to the fact that the personal trainers and dieticians are out of reach for normal people.
Look at billionaires if you want the real proof - Jeff Bezos hasn’t always looked like Vin Diesel, old pictures of Elon Musk are an amazing contrast, ditto for Gates - honestly Zuckerberg seems to be the exception here because martial arts a life long hobby of his… these are all people who already had a shit ton of money but even they struggled before they had a team dedicated to their body.
