GPT and fatty liver disease: Additionally, histological and molecular analyses were performed to evaluate hepatic steatosis, intestinal barrier integrity, and muscle oxidative status.<h4>Results</h4>Both strains significantly attenuated body weight gain and adiposity, reduced serum liver injury markers (γ-GTP, ALT, AST), and improved systemic metabolic parameters by restoring serum GLP-1 levels and reducing hyperinsulinemia.
