Preoperative low-energy diets for patients with body mass index 30kg/m2 undergoing non-bariatric surgery: A pilot feasibility randomized clinical trial and a systematic review and meta-analysis of efficacy data

Key Points

• The aim is to assess the feasibility of preoperative low-energy diets in patients with a BMI greater than 30 for non-bariatric surgery and evaluate efficacy through a systematic review.
• Pilot randomized clinical trial assessing low-energy diets
• Participants with BMI > 30 undergoing non-bariatric surgery
• Systematic review and meta-analysis of existing efficacy studies
• Demonstrated feasibility of implementing low-energy diets preoperatively
• Indicated potential efficacy benefits of diet intervention
• Enhancements in preoperative weight management observed
