About someone’s weight at all? I get that you have implied from your personal study that “being fat,” a very subjective term, is against the WoW, but you’ve misunderstood.
Contrary to popular belief on CB there are other factors that play into an individual’s weight other than calories in - calories out. To say that someone with hypothyroidism, for example, isn’t following the WoW because their body fat content is above a certain percentage or because they are “fat” is wrong and a harmful accretion.
The temple recommend question is “Do you understand and obey the WoW?” If you understand it and say that being fat means you are not following it then your answer to that question must be “no.”
