Dietitians' utilization, attitudes, and experiences towards low-energy diets and very low-energy diets in dietary treatment of obesity

The prevalence of overweight and obesity is increasing, and effective weight management care is needed. The present cross-sectional study aims to investigate the utilization, attitudes, and experiences of Low-Energy Diets (LED) and Very Low-Energy Diets (VLED) in the treatment of severe obesity among Danish clinical dietitians. Additionally, it seeks to identify barriers and motivation to implement these diets, and evaluate the need for additional resources and training among dietitians. In total, 76 Danish dietitians were included. Only 16% of participants currently employ LED or VLED, a much lower rate compared to similar international contexts. The primary barriers identified include doubts about long-term effectiveness, a concern for inducing disordered eating, and a preference for gradual lifestyle changes as recommended by health authorities. Responses highlighted a demand for additional training to boost dietitians' confidence and understanding of these dietary strategies. In conclusion, this study highlights a need for enhanced educational efforts and resources to better integrate LED and VLED into obesity treatment in Denmark. It recommends focusing on patient-centered and individualized treatment approaches to address concerns and improve dietitians' practical experiences, with the potential to include these diets in the overall treatment of obesity in Denmark.
