Metabolic fatty liver disease (MASLD/NAFLD)
ModerateStrongin favorRecommendation: Exercise is recommended for people with metabolic fatty liver disease (MASLD/NAFLD).
Rationale
Exercise reduces liver fat in people with metabolic fatty liver disease (MASLD/NAFLD). The certainty of the evidence for the critical outcomes is moderate. The recommendation is therefore strongly in favor, because the benefits clearly outweigh the risks.
Cautions and contraindications
Before prescribing physical activity, perform pre-participation screening and stratify cardiovascular risk: people with known chronic disease — cardiovascular, metabolic, renal — as well as those with suggestive symptoms not yet evaluated, require medical clearance before starting. Individualize the dose according to the clinical condition, comorbidities, and the patient's osteoarticular and functional limitations, and prefer supervised settings for complex cases and for decompensated patients. Advise stopping exertion and seeking immediate medical evaluation in the presence of warning signs such as chest discomfort, breathlessness disproportionate to effort, persistent dizziness, fainting, and unusual palpitations. Progress gradually and reassess tolerance periodically.
