Blubber-Vision
This is what many overweight people have when they criticize or point out the thinness of people who are actually at a healthy weight level. The majority of thin criticism comes from overweights who suffer from “Blubber-Vision”. This is especially acute when the overweight person has recently gained and subconsciously justifies it by looking down on people with healthy weight -- viewing others' body mass through the lenses of their own obesity.
My Aunt Sally suffers from Blubber-Vision. She is always saying how thin and unhealthy I look, even though she weighs 300 lbs.
