That's what body positivity is about. To be able to lie to yourself about how your body feels, how various body parts look and feel from 1st person perspective, then advances to be able to lie to yourself about how your fat body totally doesn't get in the way of daily life and enjoyment, and how fat ailments are totally not caused by their fat, and, ultimately, to lie to themselves while looking at pictures of themselves or in mirrors. That's the final stage. Complete acceptance of defeat.
