Abstract
- Background: Predicting an individual's success in a non-surgical weight loss approach is a demanding need since obesity is becoming an epidemic burden. A possible predictive marker is myostatin, a member of the transforming growth factor b superfamily, which has been shown to be an important regulator of muscle homeostasis. Methods: In the present study, we analyzed myostatin as a marker to predict weight loss of patients that participated in a 2 phased weight reduction program, comprising a weight loss period of 12 weeks and a weight stabilization period of 40 weeks. Therefore, 62 obese individuals with a mean BMI of 40.6 kg/m<superscript>2</superscript> were included. Plasma myostatin was measured with ELISA at the beginning (T0), after weight loss (T1) and at the end of the program (T2). Results: Although significant weight loss of - 23.9 ± 14.9 kg was achieved, myostatin did not change significantly during the program (T0 > T1: p = 0.46; T1 > T2: p = 0.70; T0 > T2: p = 0.57). Myostatin at baseline did neither negatively correlate with the achieved weight loss in the weight reduction phase (T0 > T1: r = 0.27, p = 0.16) nor with weight loss during the whole program (T0 > T2: r = 0.20, p = 0.29). Only a minor correlation with myostatin levels after weight loss with weight regain during maintenance period was detected. (T1 > T2: r = - 0.37, p = 0.05). Conclusion: Plasma myostatin might be suitable in predicting weight regain after marked weight loss, but no association with weight loss was observed in patients undergoing a non-surgical weight loss program. Therefore, myostatin does not seem to be a predictor for success in non-surgical weight loss approaches. [ABSTRACT FROM AUTHOR]
