Intermittent fasting, a dietary approach that involves alternating periods of eating and fasting, has gained significant attention in recent years due to its potential health benefits. A new study published in the journal *eLife* has added to the growing body of evidence supporting the potential of intermittent fasting in preventing liver cancer. The study found that intermittent fasting causes rapid cell division in the liver, which could potentially help prevent liver cancer.
Liver cancer is one of the leading causes of cancer-related deaths worldwide, and its incidence is increasing. Hepatocellular carcinoma (HCC) is the most common type of liver cancer, accounting for about 90% of all cases. Non-alcoholic fatty liver disease (NAFLD) and cirrhosis are the most common risk factors for HCC. Emerging evidence suggests that intermittent fasting can reduce the risk of cancer development and improve response and tolerance to treatment through the metabolic and hormonal adaptations induced by the low energy availability that impairs cancer cells’ adaptability, survival and growth.
