Junk food can make you really high, but it goes fast so you must eat and eat and eat and eat, it is vicious cycle in where you put your state of hunger (which is absolutely normal and good) as state of panic and depression. So you start eating pretty much non stop due to being in bad state of mind and getting fatter doesn't make it easier. With time you are getting more disabled and people are more severe with word that hits more and more so you get back to food which is heaven like, taking away all pain and worries for time you eat and after you finish you go and eat some more. At some point someone will enable you to get more food either a close partner or family, bringing more and more so you can be happy and all while clearly getting more sad and depressed. It is a trap, when you have 5 kg it is easy, when you get 20kg a little more, but add 100kg or more plus years of living with it and you cannot simply lose it if you don't have willpower which many simply don't have. Everything becomes hard, because you have fried your brain by giving it nonstop dopamine shots with quick food and quick culture. To lose weight you need discipline, but you not only lost body muscles but also brain muscles.
I think it is saddest and cruelest thing that happens to human being currently as it can be easily avoided and is not a sudden sickness due to genetics or accident, but caused mostly by our current instant culture of here, now, quick and fast.
