Mindfulness-based interventions for weight loss: a systematic review and meta-analysis

Area of Science:

• Behavioral Science
• Clinical Psychology
• Public Health

Background:

• Growing interest in mindfulness-based interventions (MBIs) for weight management and obesity-related eating behaviors.
• Inconsistent findings in previous reviews necessitate a comprehensive analysis.

Purpose of the Study:

• To conduct an effect-size analysis to evaluate the efficacy of MBIs for weight loss.
• To assess the impact of MBIs on obesity-related eating behaviors.

Main Methods:

• Systematic review of studies from multiple databases (e.g., PubMed, Web of Science) up to March 2017.
• Inclusion of 18 publications comprising 19 studies with 1,160 participants.
• Effect-size analysis using Hedge's g to quantify intervention effectiveness.

Main Results:

• MBIs demonstrated moderate effectiveness for weight loss (Hedge's g = 0.42) and significant effectiveness in reducing obesity-related eating behaviors (Hedge's g = 0.70).
• Weight loss was 6.8 lb at post-treatment and 7.5 lb at follow-up.
• Combined informal and formal meditation practices showed larger effects on weight loss compared to formal practice alone.

Conclusions:

• MBIs are effective for reducing weight and improving eating behaviors in individuals with overweight and obesity.
• Further research is recommended to explore the long-term efficacy of MBIs for weight loss maintenance.
