Aim: We decided to evaluate the modifications in transaminases levels after a pMR hypocaloric diet in subjects with obesity and elevated fatty liver index (FLI). Material and methods: A sample of 606 patients with obesity and FLI \u2265 60 were enrolled and treated during 3 months with a pMR diet. Patients were divided as group I (Alanine amino transferase (ALT) normal) or group II (ALT \u2265 43 UI\/L). Results: Body mass index, body weight, total fat mass, waist circumference, blood pressure, fasting glucose, total cholesterol, Low-density lipoprotein (LDL) cholesterol, triglycerides, insulin, Homeostasis Model assessment (HOMA-IR), and FLI index improved significantly in the total group with pMR diet, without differences between group I and II. ALT, aspartate aminotransferase activity (AST), Gama glutamine transferase (GGT), and ratios of AST\/ALT improved in both groups, too. This improvement was higher in group II (deltas group I vs. deltas group II); ALT (\u22124.2 \u00b1 0.9 UI\/L vs. \u221232.1 \u00b1 5.7 UI\/L: p = 0.01), AST (\u22124.8 \u00b1 1.8 UI\/L vs. \u221214.1 \u00b1 1.9 UI\/L: p = 0.02), GGT (\u22124.8 \u00b1 1.4 UI\/L vs. \u221237.1 \u00b1 4.2 UI\/L: p = 0.01), and AST\/ALT ratio (\u22120.04 \u00b1 0.002 units vs. \u22120.19 \u00b1 0.04 units: p = 0.01). Conclusions: We reported that a pMR diet is an effective method to lose weight and to improve metabolic parameters in patients with obesity and high FLI. The decrease in liver parameters was greater in patients with ALT \u2265 43 UI\/L.<\/jats:p>","DOI":"10.3390\/nu14245353","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T07:59:21Z","timestamp":1671436761000},"page":"5353","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effects of a Short-Term Meal Replacement Hypocaloric Diet in Subjects with Obesity and High Fatty Liver Index"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1745-9315","authenticated-orcid":false,"given":"Daniel de","family":"Luis","sequence":"first","affiliation":[{"name":"Center of Investigation of Endocrinology and Nutrition, Department of Endocrinology and Investigation, Medicine School, Hospital Clinico Universitario, University of Valladolid, 47003 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Primo","sequence":"additional","affiliation":[{"name":"Center of Investigation of Endocrinology and Nutrition, Department of Endocrinology and Investigation, Medicine School, Hospital Clinico Universitario, University of Valladolid, 47003 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olatz","family":"Izaola","sequence":"additional","affiliation":[{"name":"Center of Investigation of Endocrinology and Nutrition, Department of Endocrinology and Investigation, Medicine School, Hospital Clinico Universitario, University of Valladolid, 47003 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Jose","family":"Lopez","sequence":"additional","affiliation":[{"name":"Center of Investigation of Endocrinology and Nutrition, Department of Endocrinology and Investigation, Medicine School, Hospital Clinico Universitario, University of Valladolid, 47003 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"146","DOI":"10.1017\/S0029665121003815","article-title":"Non-alcoholic fatty liver disease: a multi-system disease influenced by ageing and sex, and affected by adipose tissue and intestinal function","volume":"81","author":"Bilson","year":"2021","journal-title":"Proc.
