Skin-and-bone is a term used to describe someone who is excessively thin or emaciated. However, not everyone wants to refer to an individual in this way, as it can be seen as insensitive or disrespectful. Instead, you can use antonyms for the term, which describe someone who is healthy, robust or well-nourished. These antonyms include "plump," "chubby," "curvaceous," "heavy," "portly," "full-figured," "stout," "beefy," and "bulky." By using these antonyms, you can describe a person's weight and appearance respectfully and avoid any unpleasant connotations that may be associated with the term skin-and-bone.
