fasting

Fasting has been discussed extensively by Andrew Huberman on the Huberman Lab, covering various aspects and benefits. Here are some key points from the podcast:

1. Growth Hormone Increase: Fasting can lead to a significant increase in growth hormone levels, primarily through the action of ghrelin, the hunger hormone. Ghrelin can mimic growth hormone-releasing hormone, thereby doubling growth hormone levels in the waking state 1.

2. Metabolic Benefits: Time-restricted feeding or intermittent fasting aligns eating patterns with our natural biological rhythms. A study found that compressing eating into a shorter window, such as a six-hour period, can lower glucose and insulin levels significantly compared to a twelve-hour window 2.

3. Health and Longevity: Longer fasting periods and fasting mimicking diets stimulate processes like autophagy and have been linked to mental clarity, improved metabolic health, and potential longevity benefits. They are believed to help the body cleanse itself and potentially improve conditions like depression due to an interaction between glucose levels and brain function 3 4.

4. Patterns and Protocols: Various fasting strategies are explored, such as alternate day fasting and extended fasting. However, Huberman notes that while some patterns like alternate day fasting can be effective, they might not be practical for sustained periods. Time-restricted feeding within a daily cycle often proves to be more sustainable and tested 5.

Fasting, whether intermittent or prolonged, seems to offer substantial benefits, but the right method depends on individual lifestyle and health goals. Always consult with a healthcare provider before drastic changes to diet or fasting routines.
