New Publication from the High Impact Nutrients Journal Describing the Discernment Process Between Food Addiction and Dietary Restraint

ABSTRACT:

Converging evidence from both animal and human studies have implicated hedonic eating as a driver of both binge eating and obesity. The construct of food addiction has been used to capture pathological eating across clinical and non-clinical populations.

There is an ongoing debate regarding the value of a food addiction “diagnosis” among those with eating disorders such as anorexia nervosa binge/purge-type, bulimia nervosa, and binge eating disorder. Much of the food addiction research in eating disorder populations has failed to account for dietary restraint, which can increase addiction-like eating behaviors and may even lead to false positives.

Some have argued that the concept of food addiction does more harm than good by encouraging restrictive approaches to eating. Others have shown that a better understanding of the food addiction model can reduce stigma associated with obesity. What is lacking in the literature is a description of a more comprehensive approach to the assessment of food addiction. This should include consideration of dietary restraint, and the presence of symptoms of other psychiatric disorders (substance use, posttraumatic stress, depressive, anxiety, attention deficit hyperactivity) to guide treatments including nutrition interventions.

The purpose of this review is to help clinicians identify the symptoms of food addiction (true positives, or “the signal”) from the more classic eating pathology (true negatives, or “restraint”) that can potentially elevate food addiction scores (false positives, or “the noise”). Three clinical vignettes are presented, designed to aid with the assessment process, case conceptualization, and treatment strategies. The review summarizes logical steps that clinicians can take to contextualize elevated food addiction scores, even when the use of validated research instruments is not practical.

David became a Registered Dietitian Nutritionist (RDN) in 2013 and founded Nutrition in Recovery, a group practice of RDNs specializing in the treatment of eating and substance use disorders. In 2017, David received the “Excellence in Practice” award at the national Food and Nutrition Conference and Expo. The California Academy of Nutrition and Dietetics awarded him the “Emerging Dietetic Leader Award” in 2020. He earned his PhD from UCLA’s Fielding School of Public Health in the Community Health Sciences department (with a minor in Health Psychology) by investigating the links between adverse childhood experiences and various mental health outcomes among socially disadvantaged men. His treatment philosophy is based on a biopsychosocial model which incorporates an understanding of biological mechanisms, psychological underpinnings, and contextual factors that integrate the social determinants of health. His website Wise Mind Nutrition offers a fully online interactive treatment program that will be available in the Summer of 2022.
