Fasting, especially intermittent fasting, has been shown to potentially improve liver health in some studies. While it's not a direct "repair" mechanism, fasting can reduce liver fat accumulation and improve liver enzyme levels, which are indicators of liver health.
However, it's important to note that more research is needed to fully understand the long-term effects of fasting on liver health and to establish specific recommendations.
It's also crucial to consult with a healthcare professional before starting any fasting regimen, especially if you have pre-existing health conditions or are taking medications.
