Emotional Eating Interventions for Adults Living with Overweight or Obesity: A Systematic Review and Meta-Analysis.

BACKGROUND

Emotional eating (EE) may be defined as a tendency to eat in response to negative emotions and energy-dense and palatable foods, and is common amongst adults with overweight or obesity. There is limited evidence regarding the effectiveness of interventions that address EE.

OBJECTIVES

To synthesize evidence on the effectiveness of EE interventions for weight loss and EE in adults living with overweight or obesity.

METHODS

This is a systematic review and meta-analysis. Adhering to the PRISMA guidance, a comprehensive electronic search was completed up to February 2022. Random effects meta-analysis was carried out to determine the percentage change in weight and EE scores.

RESULTS

Thirty-four studies were included. The combined effect size for percentage weight change was -1.08% (95% CI: -1.66 to -0.49, I = 64.65%, = 37), once adjusted for publication bias. Similarly, the combined effect size for percentage change in EE was -2.37%, (95% CI: -3.76 to -0.99, I = 87.77%, = 46). Cognitive Behavioural Therapy showed the most promise for reducing weight and improving EE.

CONCLUSIONS

Interventions to address EE showed promise in reducing EE and promoted a small amount of weight loss in adults living with overweight or obesity.
