The increasing prevalence of NAFLD accommodates similar developments for type 2 diabetes and diabetes-related comorbidities and complications. Therefore, early detection of NAFLD is an utmost necessity. Potentially helpful tools for the prediction of NAFLD are liver fat indices. The fatty liver index (FLI) and the NAFLD-liver fat score (NAFLD-LFS) have been recently introduced for this aim. However, both indices have been shown to correlate with liver fat status, but there is neither sufficient data on the longitudinal representation of liver fat change, nor proof of a diet-independent correlation between actual liver fat change and change of index values. While few data sets on low-fat diets have been published recently, low-carb diets have not been yet assessed in this context. Aim: We aim to provide such data from a highly effective short-term intervention to reduce liver fat, comparing a low-fat and a low-carb diet in subjects with prediabetes. Methods: Anthropometric measurements, magnetic resonance (MR)-based intrahepatic lipid (IHL) content, and several serum markers for liver damage have been collected in 140 subjects, completing the diet phase in this trial. Area-under-the-responder-operator-curves (AUROC) calculations as well as cross-sectional and longitudinal Spearman correlations were used. Results: Both FLI and NAFLD-LFS predict liver fat with moderate accuracy at baseline (AUROC 0.775\u20130.786). These results are supported by correlation analyses. Changes in liver fat, achieved by the dietary intervention, correlate moderately with changes in FLI and NAFLD-LFS in the low-fat diet, but not in the low-carb diet. A correlation analysis between change of actual IHL content and change of single elements of the liver fat indices revealed diet-specific moderate to strong correlations between \u0394IHL and changes of measures of obesity, \u0394TG, and \u0394ALT (all low-fat, only) and between \u0394IHL and \u0394GGT (low-carb, only). With exception for a stronger decrease of triglycerides (TG) levels in the low-carb diet, there is no statistically significant difference in the effect of the diets on anthropometric or serum-based score parameters. Conclusion: While liver fat indices have proved useful in the early detection of NAFLD and may serve as a cost-saving substitute for expensive MR measurements in the cross-sectional evaluation of liver status, their capability to represent interventional changes of liver fat content appears to be diet-specific and lacks accuracy. Liver fat reduction by low-fat diets can be monitored with moderate precision, while low-carb diets require different measuring techniques to demonstrate the same dietary effect.<\/jats:p>","DOI":"10.3390\/nu10020157","type":"journal-article","created":{"date-parts":[[2018,1,31]],"date-time":"2018-01-31T05:51:17Z","timestamp":1517377877000},"page":"157","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Liver Fat Scores Moderately Reflect Interventional Changes in Liver Fat Content by a Low-Fat Diet but Not by a Low-Carb Diet"],"prefix":"10.3390","volume":"10","author":[{"given":"Stefan","family":"Kabisch","sequence":"first","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"},{"name":"German Center for Diabetes Research (Deutsches Zentrum f\u00fcr Diabetesforschung e.V.), Ingolst\u00e4dter Landstra\u00dfe 1, 85764 Neuherberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sabrina","family":"B\u00e4ther","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"},{"name":"German Center for Diabetes Research (Deutsches Zentrum f\u00fcr Diabetesforschung e.V.), Ingolst\u00e4dter Landstra\u00dfe 1, 85764 Neuherberg, Germany"},{"name":"Department of Geriatrics, Campus Virchow, Charit\u00e9 University Medicine, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrike","family":"Dambeck","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"},{"name":"German Center for Diabetes Research (Deutsches Zentrum f\u00fcr Diabetesforschung e.V.), Ingolst\u00e4dter Landstra\u00dfe 1, 85764 Neuherberg, Germany"},{"name":"Department of Geriatrics, Campus Virchow, Charit\u00e9 University Medicine, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margrit","family":"Kemper","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"},{"name":"German Center for Diabetes Research (Deutsches Zentrum f\u00fcr Diabetesforschung e.V.), Ingolst\u00e4dter Landstra\u00dfe 1, 85764 Neuherberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christiana","family":"Gerbracht","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caroline","family":"Honsek","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Sachno","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"},{"name":"German Center for Diabetes Research (Deutsches Zentrum f\u00fcr Diabetesforschung e.V.), Ingolst\u00e4dter Landstra\u00dfe 1, 85764 Neuherberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6887-0016","authenticated-orcid":false,"given":"Andreas","family":"Pfeiffer","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, German Institute of Human Nutrition Potsdam-Rehbr\u00fccke, Arthur-Scheunert-Allee 114-116, 14558 Nuthetal, Germany"},{"name":"German Center for Diabetes Research (Deutsches Zentrum f\u00fcr Diabetesforschung e.V.), Ingolst\u00e4dter Landstra\u00dfe 1, 85764 Neuherberg, Germany"},{"name":"Department of Endocrinology, Diabetes and Nutrition, Campus Benjamin Franklin, Charit\u00e9 University Medicine, Hindenburgdamm 30, 12203 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bedogni, G., Bellentani, S., Miglioli, L., Masutti, F., Passalacqua, M., Castiglione, A., and Tiribelli, C.
