skin-and-bones

Dangerously thin physique

Skin-and-bones describes extreme thinness—a person or animal so emaciated that only skin and the skeleton beneath seem to remain: The stray cat was nothing but skin and bones.

The phrase emphasizes visible boniness and lack of flesh, suggesting malnutrition, illness, or neglect.

Often appears as nothing but skin and bones or all skin and bones.
