What counts as a “disorder” is often not based on empirical evidence but on what is determined as undesirable, maladaptive, or outside the social norm…by Americans. The DSM in many ways represents the worst of so-called social science.
The exercise and food science people are the worst of social science buddy. Or just “social” something, because it’s not science. “Science-based” always makes me laugh.
The DSM only matters if somebody is actively seeking treatment for something that they have a problem with in their own situation. So what’s in there is totally irrelevant for the public at large. It’s only if somebody shows up and says there’s something going on that they don’t like. It’s really just billing codes, man. The reality is far different anyway, and it just gets distilled down to these primitive codes.
With the same argument, we could arguue that working and social life are getting in the way how I am, thus working and social life should be considered disorders.
