When Life in the Fasting Lane Takes a Turn for the Worse: Intermittent Fasting and Eating Disorders

Intermittent fasting (IF) is the “diet du jour” and continues to gain popularity. But life in the fasting lane can take a turn for the worse, especially for someone who is vulnerable to disordered eating behaviors. In this presentation, we will take a deeper dive into the current body of research that supports intermittent fasting, comparing and contrasting it with what research has told us about general “weight loss,” intuitive eating and metabolic health. We will contrast the short- and long-term effects of circadian rhythm and meal timing on metabolism and physical activity in relationship to IF principles. Most importantly, we will examine the principles of intermittent fasting that can trigger disordered eating behaviors and the clients who are most vulnerable. In conclusion, questions to help guide your discussion with your clients around their vulnerability to the risks of intermittent fasting will be discussed.
