You don't have a food problem, you have a dopamine problem, food is just the vehicle that gets you to the high, the high being that dopamine hit, yet every time after the first we go seeking that hit, the brain naturally reduces it so we don't get stuck in a feedback loop, so if your dopamine vehicle is food, you have to consume more and more food to get where you want to be and there are limits, either physical or mental, like my brother used to just eat--purge--eat again because the pursuit for the dopamine got so intense for him.
The problem is when you want to stop, you can stop eating, fast for a week, your appetite will reduce dramatically, yet the want for that dopamine hit won't, it'll just be a gaping hole of discomfort on your psyche. You are literally a drug addict, the only difference is your drug is food.
You have much higher issues than just food, resolve those first, the fact that your in a majority of people within this country at that size is truly terrifying, you don't have the healthcare infrastructure to care for all these people down the line and the people doing it are making trillions so they'll never stop.
However, is it surprising? No, not at all because the dopamine chase is what fueled survival in us for millions of years, some people are just wired to chase it, back then those same people would of been apex human beings because there was no feedback loop to get caught up in.
Truly, the vast majority of the world is caught up in a psychological dopamine feedback loop in some way or another, here we chase after tail, same thing, same dopamine hit just a different vehicle.
This is the point of adopting a purpose in your life, to have a vision beyond the dopamine hit so you can simply look at it for what it is, as opposed to something that should be chased after fruitlessly.
