I suppose self-induced when the weapon is food is, technically, natural.
I’m reading someone (very sadly) doing destructive testing on their own cardiovascular, pulmonary, integumentary, and alimentary systems, seemingly without a control specimen.

Cause this kind of severely disordered eating is a very good pathway there.
EDIT: I ask this as someone who has spent a literal lifetime struggling with both disordered eating and suicidal ideation.
