ofc, all these issues gathered is what makes a huge difference.
but nowadays people grow up with a mentality that being fat is not something to be ashamed of and you can be model or anything else
If people were already ashamed of it from the beginning, it would have a greater impact than fast foods or anything else. That's what I meant.
See, people just do not care about their lives anymore too, for example: "Smoking cigarettes can kill you" some people still start to smoke to look cool, because they care about what people thinks about them. like: "OMG I'll start cigar to be like Andrew Tate to look like a gangster." So cool ~ !
It is in that sense that I meant it. Inspiration way.
Since other people will think you're cool, then you'll keep doing that action. (Being fat in this context)
If people hate you, you'll be less comfortable doing it and will try to change since nobody wants to be bad spoken.
Still, some countries is cool to be "diverse" or more acceptable since it makes you to look cool.
I'm just giving an example and that medias really affect way more than other factors, especially in young people.
