This is one of the most well-thought out comments I've read on the internet in a while. I'm an R&D chemist in pharma/medical devices. I have run across many food industry chemists in my career. They absolutely attested to formulating junk foods to have the best possible taste and the least possible satiation/nutritional value, so you crave more of it. Their narcissistic sociopath bosses are driven only by sales, just like mine, and their jobs rely on churning out the next beetus bomb, so they do it because they have families to feed.  I don't work on any of the fatty-treatment drugs but I find it hilarious that my industry develops so many drugs (see: lipitor, metformin, CPAP machines) to treat symptoms of the diseases my food-industry-chemist brothers unleash upon their land with their fucking XXXXL SuperMegaMonsterSnackBuster bullshit. Both our jobs would go away in an instant if people would just consume what they need, and maybe a little more on holiday.
