Health Nazi 

A person who forces his or her healthy lifestyle on others through supporting legal bans of anything unhealthy. As well as being an all around A-hole to anyone who isn't like them. Such people generally have a "holier-than-thou" attitude all around, are only looking for yet another reason to look down on people who don't live up to their perceived view of the world.

Don't be such a health Nazi!

health nazi 

A weight-loss "expert", usually weighing excess of 300 pounds, that tries to mentally scar skinny kids by telling them how drugs, McDonald's, and themselves are killing people.

I went to the health nazi yesterday. She told me I will have a heart attack at age 17.

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.

Guy 1: Check out this bento box I made! I decided to include those little hot dog octopuses in it, because I thought they were a cute idea.

Guy 2: Ooh that looks yummy

Guy 3: Cool post, but actually, hot dogs are really high in sodium and nitrates, so they are awful as a source of protein. I urge you to use anything else, preferably something leaner. Eating these all the time will make you fat, and fat is unhealthy. Sorry if that last part offends you, but that’s just facts.

Guy 1: I…don’t eat hot dogs all the time??? This is the first time I’ve had them in months.

Guy 2: aw goddammit, not another health nazi. Go piss on someone else’s post.
