I think it's the same reason slim peeps don't like to be called Thin
It gives the impression they are sick.

It's because being called fat is perceived as an offensive word, commonly used to make fond of the physical appearance of an individual, rather than a mere description, like tall or slim.

It is to my understanding that "fat" is not a medical term. Medically you are overweight or obese.

A school of thought tells us we humans don't like hearing the truth about ourselves. And for some unknown reason, we have believed that the realization of truth will usher us into a state of unhappiness (which is a choice the mind makes after weighing physical circumstances as against inner resolve and an emotional state). Consequently, we choose to live in a fake world, one that we foolishly and endlessly try and fail woefully to sustain with a fake lifestyle of over-indulgence on material wealth and the show of it.

An obese lady, instead of working on her body mass (remember weight according to Mr Physics varies from place to place on the earth) would rather adorn herself with cheap cosmetry and other artificialities in order to distract and give herself and onlookers the impression of a physical beauty she knows in the depths of her soul she does not possess, and over time, what do we have - a lady adding muscle fat in all the wrong places, and where there was once beauty and form intermingled with grace we have a graceless, bulgy physique adorned with cellulite, folds and flabs (covered with the distraction of tight, body-hugging clothing) with a belly competing with that of a pregnant woman, and a body overworking its heart with a grandeur similar to that of the engine of an okada trying to power a submarine...such a woman's self esteem becomes inversely proportional to her body mass, which is why the average woman would always tell you they don't know their body mass (after eyeing you with a malice that can kill a leviathan); truth is they know it but they refuse to keep it in their conscious and would rather make a mental note to remember to forget the fact that they are not healthy and fit health-wise.

Another school of thought states that the noun or adjective "fat" is somewhat impolite and void of decorum. We are meant to say a lady is "plump" instead of "fat", and though Courtesy demands this, she cannot force everyone to do her bidding.

This is a question thrown at the ladies so I answered using them as the subject-topic, I am not a chauvinist so I shall not carelessly say men are not guilty of being obese as well, such a statement goes without saying...

Would to God that we can watch our weights and our words the same way we watch our phones; the world would be a much better place in two-thirds of a heart beat.

Then where do u belong
