Specific Dietary and Exercise Methods to Improve Fatty Liver: A Hepatologist’s Guide

1.Dietary Therapy: The Essence of “What and How” to Eat for a Liver-Friendly Diet

It is said that approximately 80% of fatty liver improvement depends on diet—not just calorie restriction, but the “quality” and “method” of eating matter greatly.

1ー1.How to Choose Liver-Friendly Foods and Specific Intake Methods

Vegetables, Mushrooms, and Seaweed: Powerful Allies for Detox and Antioxidation

Green and yellow vegetables are rich in vitamin K, supporting the liver’s blood coagulation function; β-carotene in carrots and pumpkin helps protect liver cells. Cabbage and broccoli offer detoxifying properties that support liver function. Mushrooms are rich in β-glucan and dietary fiber, enhancing liver immune function and helping improve fatty liver and cholesterol levels. Fucoidan and alginic acid in seaweed balance the gut environment, reducing liver burden. “Vegetable-first” is effective for preventing sharp blood sugar rises.

Quality Protein: Supporting Liver Repair and Metabolism

Omega-3 fatty acids (EPA, DHA) in oily fish (rich in EPA and DHA) promote fat metabolism in the liver and help control fatty liver and cholesterol levels. Soybean products are low in calories and kind to the liver; isoflavones and lecithin support fat metabolism. Limit processed meats like bacon and sausage, which are high in salt and fat.

Surprising “Saviors”: Coffee and Laughter

“1–2 cups of black coffee daily has been shown in research to suppress liver inflammation” through chlorogenic acid. It has also been found that laughing for 20+ minutes daily reduces visceral fat and improves liver function.

1ー2.Dietary Habits That Don’t Worsen Fatty Liver

“Eat slowly” is key—chewing each bite approximately 30 times prevents overeating and suppresses sharp blood sugar rises. Switch sugary beverages like soft drinks, sports drinks, and sweetened coffee to water or unsweetened tea. Avoid processed foods like snacks and instant foods, which place heavy burden on the liver. Ideally, finish dinner at least 3 hours before bedtime.

2.Exercise Therapy: Approaching “Body Composition Improvement” You Can Sustain

Exercise is an important element for burning fat accumulated in the liver and improving insulin function.

2ー1.Combining Aerobic Exercise with Resistance Training

Walking: use a moderate/maintenance pace for health maintenance, and a fat-burning pace for physical improvement and fat burning. Target approximately 30 minutes per day, 3+ times per week to start, aiming for “250 minutes of moderate-to-high intensity exercise weekly” as you become accustomed.

Resistance training: incorporating squats, sit-ups, and push-ups 2–3 times per week raises basal metabolism and creates a body that burns fat more easily.

2ー2.Incorporating “Incidental Exercise” Into Daily Life

Walking one extra train stop during commuting, using stairs instead of elevators—regularly moving throughout daily life is effective. The key to consistency: don’t suddenly start vigorous exercise; step up gradually in accordance with your own fitness level.

3.The Next Step for Not Giving Up, as Told by a Specialist

If no improvement is seen despite effort with diet and exercise, the most important thing is to consult a specialist without hesitation. Even among thin individuals, fatty liver can occur, and risk of progression to NASH may be high. Liver regenerative medicine using stem cells may suppress liver inflammation, suppress fibrosis progression, and promote repair and regeneration of damaged liver cells.
