My problem with "Orthorexia" is that it is often used to stigmatise and as you put it "food shame" those who take healthy eating seriously. I get the side eye when I open up my lunches sometimes from the fatties where I work. They insist that IM the one with an unhealthy obsession. I have people going "you sure" when I say "no thank you" to an offer of sweets, and coworkers tutting and going "oh she doesnt eat BAD STUFF" in a sarcastic tone. I would argue that the food shaming is coming from unhealthy fatasses trying to be crabs in a bucket. This whole article comes off as condescending and just an ill informed way to further shame healthy people and push the fat acceptance agenda.
