                                According to the National Institute of Mental Health (NIMH), eating disorders affect an estimated 9% of the U.S. population during their lifetime. Understanding the terminology and consequences of restricted food intake is the first step toward recognizing potential issues in yourself or others. While the simple answer is "undereating," the medical and psychological conditions associated with eating too little are far more complex.
