Hot take: people should not celebrate or endorse obesity. Making something that is very unhealthy seem okay isn't right, especially something like weight.
Edit: I wholeheartedly do not mean to insult or make anyone feel bad. I support anyone who is fat, being fat does not make you a bad person or anything, but it's extremely important to understand that weight issues can be big health problems and it's important to care about weight.
Again, I mean no harm to anyone. If you are feeling depressed or negative, please reach out. There are people who will support you.
