Lifestyle tips

I've seen some people having fun with gluttony, but then the moment you see someone fantasizing about having a food addiction, it gets shot with an immediate reality check. So when does this stops being fun sexy and starts being a slope down suffering

It'll change based on the person. Some people are more susceptible to addiction. Also, it depends on what they pursue. It'll be pretty difficult to convince Kita its a "food addiction" when she actively pursues immobility for its own sake, has wanted to for almost 2 decades, and is just eating for the size she wants to be, for instance.

The big seperation between the two is the choice.
Gluttony is the choice to over indulge in you love of food, even if you do a stuffing and eat a huge amount of food, you are still in control over it.
The food addiction you lose control, it isn’t a choice anymore it is a uncontrollable need to cram food into your body.

As some other people said, a lot depends on the person and their perspective. On some level every single person is “food addicted” since no one can survive without food. But more seriously, I think a lot depends on someone’s self perception. If you have a more intense than average food focus and you are bothered by that, call it a food addiction, if you’re fine with your intense food focus call it gluttony. Honestly, I am very focused on food and eating and a large part of my life revolves around that. I like it and I happily label myself as a glutton, someone else looking at my life could easily call it a food addiction.
