This podcast episode focuses on identifying signs of an unhealthy liver. The interviewee presents several methods for assessing liver health, including ketone production during fasting, alcohol metabolism rate, and visual observations like eye and foot condition. Specific indicators mentioned include yellowing in the inner eye corner, dry cracked feet, and a white or black coating on the tongue. Listeners are encouraged to observe these indicators and consider dietary changes, such as consuming produce from regenerative farms, and potentially incorporating fasting and mineral supplementation to improve liver health.
