Understanding nutritional interventions and physical exercise in non-alcoholic fatty liver disease

Area of Science:

• Hepatology
• Metabolic Syndrome
• Gastroenterology

Background:

• Non-alcoholic fatty liver disease (NAFLD) is the most prevalent liver condition globally, affecting adults.
• Characterized by excessive liver fat accumulation ( >5% of liver weight) without alcohol or other causes.
• NAFLD is recognized as the hepatic manifestation of metabolic syndrome, linked to obesity, insulin resistance, and dyslipidemia.

Purpose of the Study:

• To provide an updated overview of NAFLD progression mechanisms.
• To analyze the therapeutic effects of nutritional interventions and physical activity on NAFLD.
• To explore the molecular and cellular underpinnings of lifestyle interventions for NAFLD.

Main Methods:

• Review of current literature on NAFLD pathogenesis.
• Analysis of studies investigating dietary modifications for NAFLD.
• Evaluation of research on the impact of physical exercise on NAFLD.

Main Results:

• NAFLD involves complex mechanisms including lipid accumulation, insulin resistance, oxidative stress, and inflammation.
• Nutritional strategies like low-fat diets rich in polyunsaturated fatty acids show promise.
• Physical activity, encompassing aerobic and resistance training, improves metabolic parameters and reduces liver fat.

Conclusions:

• Lifestyle modifications are the cornerstone of NAFLD management.
• Dietary adjustments and regular exercise are crucial for preventing and treating NAFLD.
• Further research is needed to elucidate precise mechanisms and optimal exercise regimens for NAFLD.
