Fat is a relative thing depending on the charity or eyesight of the observer.
This was wrong on many levels. There is absolutely no scriptural support for that assertion whatsoever and the idea of a woman being fat is a completely irrelevant aesthetic issue which has everything to do with the flesh and man's perception of it, particularly in the secular world where body image has far too high an emphasis and nothing at all to do with the spirit.

There can be a number of reasons why women are overweight or appear overweight. This can hereditary on a genetic level or may be because of water retention. Many women appear to be overweight because their metabolism is badly affected by a thyroid disorder.
You cannot apportion blame to any woman, or man for that matter, who has a problem with their metabolism.
