What are the health effects of fasting?

Fasting can have several significant health effects, both physical and mental. According to Andrew Huberman, these include:

1. Weight Loss and Glucose Regulation: Fasting, particularly time-restricted eating, is associated with weight loss. It can reduce resting blood glucose levels, which is beneficial, especially for individuals at risk of metabolic disorders 1.

2. Gut and Liver Health: Intermittent fasting can improve the gut microbiome by reducing harmful bacteria and promoting healthier gut flora, which may help with conditions like irritable bowel syndrome 2. Moreover, it can positively influence brown fat stores, which is linked to liver health and can reduce the risk of non-alcoholic fatty liver disease 3.

3. Cognitive and Mental Health: Fasting can enhance mental clarity and cognitive function due to lowered glucose levels in the brain, which can improve mitochondrial function and reduce depressive symptoms 4.

4. Hormonal and Stress Response: Fasting increases the release of hormones like epinephrine and cortisol, which can enhance alertness without pushing into chronic stress levels, if managed correctly 5.

5. Longevity and Disease Resistance: There is evidence suggesting fasting could stimulate cellular repair processes and potentially extend lifespan, although more research is needed to confirm these effects in humans 6.

Overall, fasting can set beneficial conditions in the body, impacting weight management, metabolic health, and even mental clarity, but should be approached considering individual health conditions and dietary needs.
