I agree that "unclear and often highly subjective" are downsides to categories of content that warrant trigger warnings, but this exchange (below) would pretty clearly warrant a trigger warning for eating disorders if it was on a site that used trigger warnings.
Are there effective methods of ceasing to enjoy some activity, or of refraining from enjoyable things?
For food items you can create distaste by mixing the food item with something that makes you throw up.
But if anything that actually shows how subjective this is and how much of an issue it is. It is one thing to say that trigger warnings should apply to issues that may involve PTSD. It is quite another thing to suggest that they should involve mentions of every possible mental health issue.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
