5 Causes of Binge Eating Disorder

Binge eating disorder (BED) is a complex and challenging condition that affects millions of people around the world. It's characterized by recurrent episodes of consuming large amounts of food, often rapidly and to the point of discomfort. People with BED often feel a loss of control during these episodes and experience guilt and shame afterward. While there is no one-size-fits-all explanation for the development of BED, there are several common causes and risk factors that can contribute to this condition. In this blog, we'll explore five key causes of binge eating disorder, shedding light on the complexity of this condition and the importance of a comprehensive approach to treatment and prevention.

1. Genetics

Genetics plays a significant role in the development of binge eating disorder. Research has shown that BED tends to run in families, suggesting a genetic predisposition. If a close family member, such as a parent or sibling, has struggled with BED, it increases the likelihood of an individual developing the disorder as well. While genetics don't guarantee that someone will develop BED, they can create a susceptibility to certain eating behaviors and emotional struggles that contribute to the disorder's onset.

2. Psychological Factors

Psychological factors are one of the most significant contributors to binge eating disorder. People with BED often struggle with emotional regulation, self-esteem, and body image issues. Many individuals use food as a way to cope with stress, anxiety, depression, or other negative emotions. The act of binge eating can provide temporary relief from emotional discomfort, leading to a cycle of overeating to manage these feelings. Identifying and addressing these underlying psychological issues is crucial in treating BED.

3. Dieting and Restriction

Ironically, dieting and restrictive eating behaviors can increase the risk of developing binge eating disorder. When individuals restrict their food intake or follow extreme diets, they may trigger intense cravings and compulsive eating episodes. These restrictive practices disrupt the body's natural hunger and fullness cues, making it challenging to maintain a balanced and healthy relationship with food. Over time, this can lead to the development of BED as the body seeks to compensate for periods of deprivation.

4. Environmental Factors

The environment in which a person lives can also contribute to the development of binge eating disorder. Access to an abundance of high-calorie, highly processed foods, combined with constant exposure to food-related advertisements and social pressure to achieve certain body standards, can all influence eating behaviors. For some individuals, a chaotic or stressful environment can increase the risk of binge eating as a way to cope with these stressors.

5. Brain Chemistry

The brain plays a vital role in regulating appetite and food-related behaviors. Abnormalities in brain chemistry and neurotransmitter imbalances, such as those involving serotonin, dopamine, and norepinephrine, can contribute to the development of BED. These imbalances can affect mood, impulse control, and cravings, making it difficult for individuals to resist the urge to binge eat. Understanding the neurobiological aspects of BED is essential for developing effective treatments.


Binge eating disorder is a complex condition with multiple causes and risk factors. While this blog has highlighted five common contributors to BED, it's important to remember that each individual's experience is unique. Effective treatment for BED typically involves a holistic approach that addresses both the physical and psychological aspects of the disorder.

If you or someone you know is struggling with binge eating disorder, consider seeking the guidance of a functional medicine practitioner. They can help you identify the specific causes that may be contributing to the disorder and develop a tailored plan for treatment and prevention. Remember, you don't have to face BED alone, and there are effective approaches to help you regain control of your eating behaviors and overall well-being.
