Exercise and diet modification in non-obese non-alcoholic fatty liver disease: Analysis of biopsies of living liver donors

Background and Aims: We evaluated efficacy of exercise and diet modification for steatosis improvement of non‐obese non‐alcoholic fatty liver disease (NAFLD) patients. Methods: We analyzed retrospectively the clinical and histological parameters of consecutive living liver donors, who experienced repeated liver biopsies due to steatosis and were treated using exercise and diet modification. Results: From 1995 to 2009, among a total of 1365 potential living liver donors with NAFLD seen on the initial liver biopsy, 120 consecutive donors with steatosis ≥ 30% or an estimated donor‐recipient weight ratio
