Effects of a multicomponent lifestyle modification intervention on liver function, lipid profile, and body composition in adults with elevated hepatic steatosis index

Parallel to the escalating burden of obesity is the steadily increasing prevalence of metabolic dysfunction associated steatotic liver diseases (MASLD), a chronic condition that progresses from simple steatosis to advanced stages of steatohepatitis, fibrosis, and cirrhosis (1-2). MASLD, regarded as the hepatic manifestation of metabolic syndrome is known to be exacerbated by unhealthy lifestyle choices and the presence of comorbidities such as diabetes, dyslipidemia, and obesity (3-4) . Therefore, early identification of the general population at risk of MASLD and the development of multicomponent interventions that can prevent the progression of liver damage and mitigate associated adverse cardiometabolic health outcomes are important. Our study aimed to evaluate the effects of a lifestyle modification program on glucose levels, lipid profile, liver function, and body composition measures in community-living adults with elevated hepatic steatosis index in Mumbai, India. Adults (n= 231, mean age 46.1(13.7) years), 58.6% men) were screened for risk of MASLD using a non-invasive screening tool, Hepatic Steatosis Index (HSI) (calculated as (HSI)= 8 x (ALT/AST ratio) +BMI (+2, if female; +2, if diabetes mellitus) (5). Eligible participants with HSI >36 (predictive of the presence of MASLD) were randomized to receive either a multicomponent lifestyle intervention (experimental group, EG) comprising weekly sessions of individualized dietary counseling (Participants having BMI >23kg/m2 (n = 36) received hypocaloric diets with 40% carbohydrates, 40% fat and 30% proteins (WLD) and those having BMI
