Objectives

Narrative objectives1

Fatty liver disease, lifestyle-related diseases, and chronic kidney disease are rapidly increasing. Hepatic steatosis can lead to liver fibrosis and is frequently accompanied by obesity, impaired glucose metabolism, hypertension, and other comorbidities. Increasing physical activity through aerobic exercise and resistance training, together with optimizing caloric and salt intake, is presumed to improve liver function and metabolic parameters.1) In this study, we combined exercise counseling, a dietary intervention provided by registered dietitians, and body composition assessment using InBody, and evaluated the usefulness of a 3-month intervention by examining its effects on liver function, metabolic parameters, body composition, and lifestyle behaviors.
