Obesity is a major contributor to ill health and numerous comorbidities globally. Recent studies suggest that addictive-like tendencies toward foods, especially highly processed foods, contribute to this epidemic. Therefore, interventions used to treat substance-use disorders may be effective for treating overweight/obese patients with food addiction (based on the Yale Food Addiction Scale, version 2.0). This pilot study evaluated four interventions, selected because of their effectiveness in the treatment of substance-use disorders [motivational interviewing, pharmacotherapy (naltrexone-bupropion), pharmacotherapy with motivational interviewing, information control (diet and physical activity instruction)], in overweight/obese individuals with and without food addiction. The food addiction construct identified a distinctive subset of overweight/obese individuals. Through one month, response to interventions differed between food addiction phenotypes with those who were positive for food addiction showing similar or less response to the interventions than those who were negative for the trait. This suggests that individuals with addictive-like tendencies toward food may require longer and more intensive intervention to achieve their goals. The greatest changes in biometric measures occurred between baseline and 1 month during which time participants were attending weekly intervention sessions. Across all groups, those who attended more sessions (dose) was correlated with a reduction in body mass index.
