Diet plays a key role in its progression and management. This narrative review highlights evidence-based nutritional strategies, including the Mediterranean diet, low-carbohydrate and ketogenic diets, and high-fiber intake, which improve insulin sensitivity, reduce hepatic fat, and lower inflammation. Nutritional deficiencies, such as low vitamin D, choline, and omega-3 levels, exacerbate metabolic dysfunction-associated steatotic liver disease, emphasizing the need for targeted supplementation. Emerging approaches, including gut microbiota modulation, precision nutrition, and nutraceuticals like resveratrol and curcumin, offer promising therapeutic potential. A multidisciplinary approach integrating dietary and lifestyle modifications is essential for effective metabolic dysfunction-associated steatotic liver disease management.gut microbiotahealthcareketogenic dietMASLDMediterranean dietnutraceuticalsjournal-article
