Abstract
Background & Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) management guidelines have been published worldwide; we aimed to summarize, categorize and compare their lifestyle intervention recommendations.
Approach & Results: We searched MASLD/nonalcoholic fatty liver disease (NAFLD) management guidelines published between 1 January 2013 and 31 June 2024 via databases including PubMed/MEDLINE, Cochrane, and CINAHL. In total, 35 qualifying guidelines were included in the final analysis. Guideline recommendations were categorized into five domains (i.e., weight reduction goals, physical activity, nutrition, alcohol, and tobacco smoking) and were ranked based on how frequently they appeared. A recommendation was defined as widely adopted if recommended in ≥24 (≥66.6%) of the guidelines. These included increase physical activity; reduce body weight by 7-10% to improve steatohepatitis and/or fibrosis; restrict caloric intake; undertake 150-300 or 75-150 minutes/week of moderate or vigorous-intensity physical activity, respectively; and decrease consumption of commercially produced fructose. The least mentioned topics, in ≤9 of the guidelines, evaluated environmental determinants of health, mental health, referring patients for psychological or cognitive behavioral therapy, using digital health interventions (DHIs), and assessing patients’ social determinants of health.
Conclusions: Most guidelines recommend weight reduction through physical activity and improving nutrition, as these have proven positive effects on health outcomes when sustained. However, gaps regarding mental health and the social and environmental determinants of MASLD were found. To optimize behavioral modifications and treatment, we recommend carrying out studies that will provide further evidence on social support, environmental factors, and mental health, and further exploring DHIs.
