Weird take but it seems like the one most consequential things modern society and captialism itself took from people of its interior is the idea that our bodies can actually do things.

There are absolutely people who look like this without stepping foot in the gym or paying a single iota of attention to what they eat, but it's only because of their very specific lifestyles. You won't find them in the west, but in places like Africa you will see guys who are admittedly not as big as him but just as lean and with more lean muscle mass than the average westerner. I've been to South Africa and seen guys who were miners for a living and ate a diet that was high in lean protein like eggs, fish and poultry and do physical labor all day and walk around at like 8% body fat. It's not because they care about their appearance and count calories etc, but just because they're too poor to afford addictive processed foods, are extremely active by necessity and by trial and error realize that lean protein makes you feel full for longer.

This is completely unrealistic in the west and many other places though because our diets are made up of processed foods stripped of micronutrients and packed with the addictive compounds that make us want to consume more (sugar, fat and salt). Also in the west, our lives are just less active. I work in construction and while I am definitely more active than the average westerner, it's nothing compared to people in underdeveloped countries. For instance, obesity wasn't a huge thing in Mexico until food corporations expanded there and got everyone hooked on processed garbage, and now they're fatter than the US. Corporations have stolen our health from us and got us addicted to unhealthy food.
