I had a long, overly deep answer. But yeah, basic health is where to start. You can’t trust your negative feelings when you’re body is shit. Diet disorders are more subtle than other substance abuses. It’s not a single chemical that you are addicted to. There’s so much psychology around food, on top of the physical stuff. I think the trick is in first making sure that your food is of good quality. Make things that are delicious, not because they’re overloaded with cheap calories, but because they’re naturally tasty without that shit. Once you have a diet that allows you to appreciate food, you can focus more on losing weight. Nutrition is so fundamental, everything in a person’s life is effected by it strongly.
If you want proof as to how fucked up society is, just look at how this world handles its food. We produce more than can be eaten, yet over a billion starve. We understand the science of nutrition, yet we constantly poison ourselves. Be one of the few who truly understand how valuable healthy nutrition is and protect it.
