we live in an uprecedented level of comfort with insane availability of shitty food
sugar was considered a luxury spice just a few hundreds of years ago
the truth is that people with fried dopamine receptors lack self control so they live in permanent hedonism instant gratification mode which reflects in their habits in the day to day life (food consumption, entertainment)
if you are fat and losing weight and getting fit then keep doing it, you are going to make it
if you are already fit enough try to bring your fatoid relatives and friends to the other side
