Sites in the first category, known colloquially as “thinspiration” sites, include photos of celebrities who are known to be, or suspected of being, anorexic, mostly photographed in ways that emphasize their skeleton-like features, and of anorexia patients bragging of their weight loss by showing their current appearance.

Indeed, these people are very hungry (even their hormone levels tell us this), but have decided to starve themselves in an attempt to improve a distorted image of themselves.
