Core Tip

Core tip: Non-alcoholic steatohepatitis (NASH) is a major cause of chronic liver disease. In obese patients weight reduction is recommended. We studied the effect of a soy protein-based meal replacement therapy and a therapeutic lifestyle intervention in a randomized controlled study of obese patients with NASH. Both groups significantly lost body fat and liver fat while muscle mass remained stable. Corresponding changes were found in blood lipids and adipokines. However, liver fat quality as mean chain length and saturation of lipids was modified differently by each intervention. The relevance of these findings has to be cleared by further studies.
