Your body craves carbohydrates, it's like an addiction. Overcoming that addition is all about training your willpower and delayed gratification.
It's the same as smoking. Strong willed people can stop smoking in a heartbeat. Weak minded people cannot, their minds are simply too weak to resist smoking and they need it every 2 hours. Same with eating.
Next time you feel that hunger feeling, out of spite just don't eat and the craving goes away within 1-2 hours and you'll get long term endorphins instead that make you feel good for your mind being stronger than that craving. It's not so hard, you just have to be a bit stronger than that desire.
You can also try fasting. Just don't eat for 24h and you'll feel a lot better than if you ate.
Some people simply cannot delay gratification, they need to be on their phone, watch tv constantly to get their dopamine hit. However, other people are able to delay gratification and get a much larger amount of endorphins and also the better ones.
It should become a habit to receive your dopamine hits from resisting the temptation and being stronger than this degenerate craving for unhealthy, processed food carefully designed to make the population addicted to their produce to buy more and more and eat more, so that they make more money.
There is a way to get out of this easily, don't eat any more sugar and carbohydrates, but plants and meat, which is the keto diet. It's very healthy and natural as well. You'll drop a lot of weight and you can still eat well.
