Chew and spit

Chew and Spit (CHSP or CS) is the chewing of food (that is often energy dense, and subjectively enjoyable) and spitting it out before swallowing, often in an attempt to avoid ingesting unwanted calories and nutrition.[1]

A recent systematic review[1] on the topic, revealed seven themes identified in scholarly articles[2][3][4][5][6][7][8][9][10]

  • Potential marker of eating disorder severity (regardless of length of illness
  • Appears in younger sufferers
  • Individuals who CHSP showed increased:
  • CHSP may be trans-diagnostic (i.e. appears in individuals who have been diagnosed with all or any type of clinical or sub-clinical eating disorder)

Very little is known, academically, about the psychological, physiological, and social impacts of CHSP; however, research is ongoing.
