Health Nazi

People in online discussions whose only purpose seems to be giving unwanted and unrequested health advice in their comments. The threads they choose to preach on are frequently unrelated to health advice, and their “tips” tend to be more annoying than helpful. Typically more concerned with looking smart or superior than improving the lives of people they share a digital space with. Often get snippy at the idea of someone using unhealthy ingredients in cooking, someone having self-confidence while being overweight, or even a mere mention of the terms “body positivity” or “fat acceptance.” Very common on Reddit.
