Evaluation of a meal replacement-based weight management program in primary care settings according to the actual European Clinical Practice Guidelines for the Management of Obesity in Adults

Abstract

Introduction: The purpose of this study was the evaluation of a weight loss program in primary care settings with respect to the European Clinical Practice Guidelines for the Management of Obesity in Adults with regard to the long-term success of changes in body weight and composition.Methods: Overweight and obese patients (n = 1167) who underwent a standardized meal replacement-based weight loss program (myLINE®, AENGUS, Austria) in primary care settings were included in this evaluation. Body composition was measured by conventional anthropometry and bioelectrical impedance analysis (AKERN BIA101®, BIACORPUS RX4000®, SoftwareBodycomp Version 8.4 Professional). Data of patients who participated at least 12 months in the program were analyzed retrospectively and compared with their baseline data. Results: After 12 months, a weight loss of 8.6 ± 7.5 kg (mean ± standard deviation) or 8.2 ± 7.8 % from baseline was seen (p < 0.001). In all, 71.9 % of all patients achieved a minimal weight loss of 5 %, and 18.8 % lost 15 % of their initial weight. In comparison with the baseline (35.7 ± 11.5 kg), body fat decreased to 29.6 ± 10.7 kg, which is 83.7 ± 18.9 % from baseline (100 %; p < 0.001). Body cell mass showed an absolute reduction of − 1.4 ± 2.2 kg (p < 0.001), although a relative increase of 1.5 ± 2.5 % (p < 0.001). There were no significant differences between male and female subjects regarding changes in weight, body fat, and body cell mass. Conclusion: The evaluated program complies with the European Clinical Practice Guidelines for Management of Obesity in Adults (2008), which recommend a weight reduction of 5–15 % from initial weight within 6 months. Furthermore, the data showed a significant reduction of body fat and a relative increase of body cell mass.
