Energy balance

Achieving a 7-10% weight loss through intensive lifestyle modification (diet, exercise, and cognitive-behavioral therapy) is the most effective non-surgical intervention for resolving nonalcoholic steatohepatitis (NASH) and reducing liver fibrosis in NAFLD patients.

To reverse fatty liver disease and NASH, you must lose 7-10% of your body weight. This is best achieved through a structured program combining a daily caloric deficit (500-750 kcal), at least 200 minutes of weekly physical activity (mix of aerobic and resistance), and cognitive-behavioral strategies to maintain habits. Focus on consistency over perfection, use meal planning to reduce decision fatigue, and track your weight weekly. This approach is more effective than any current medication.

GoodSupportsHIGH confidence
Several controlled studies have confirmed that an intense approach to lifestyle changes, carried on along the lines of cognitive-behavior treatment, is able to attain the desired 7%-10% weight loss, associated with reduced liver fat, nonalcoholic steatohepatitis (NASH) remission, and also reduction of fibrosis.

Why this rating

Based on multiple controlled studies, prospective cohorts, and proof-of-concept trials cited (e.g., Look AHEAD, Havana study), though mostly observational or short-term RCTs rather than long-term mortality data.
