Abstract
Excess body weight has become a problem, especially in most developed countries. Excess nutrition is harmful to the liver and causes liver diseases including nonalcoholic fatty liver disease and hepatic malignancies. A well balanced diet and adequate exercise can help maintain a healthy liver and prevent liver diseases induced by metabolic abnormalities. In contrast, infectious liver diseases such as viral hepatitis and their consequent cirrhosis and hepatocellular carcinoma can be prevented by prophylaxis, including adequate vaccination against viruses and patient education.
Keywords: Exercise, lifestyle, liver, nutrition, prophylaxis.
