Cannabis, Weight, and Weight-Related Behaviors

Published in:

Abstract

Purpose of Review

Review recent research regarding the relationship between cannabis use, weight, eating behaviors, eating disorders, and physical activity.

Recent Findings

Cannabis, particularly the cannabinoid Δ9-tegrahydrocannabinol (THC), is associated with increased appetite, food cravings, overconsumption, and decreased physical activity. Cannabidiol (CBD) appears to be associated with decreased appetite. While cannabis use is not correlated with binge eating, cannabis use disorder is associated with loss of control eating. Despite cannabis’ association with unhealthy eating and sedentary behavior, most studies suggest that cannabis use is not associated with weight gain, or may even facilitate weight loss.

Summary

The state of the literature regarding the relationship between cannabis, weight, and weight-related behaviors is complex. Most studies do not differentiate between cannabinoid profiles, routes of administration, or whether cannabis use is problematic. Patients presenting for weight management should be cautioned about cannabis, particularly THC, potentially increasing risk of unhealthy eating and activity patterns.
