Why is intermittent fasting healthy?
Sources:
Intermittent fasting is considered healthy for several reasons:
-
Improved Metabolic Health: Intermittent fasting can enhance insulin sensitivity, which is beneficial for utilizing blood sugar effectively and reducing the risk of diabetes. It also improves liver enzymes, indicating better liver function 1.
-
Gut Health: It promotes a healthier gut microbiome by supporting beneficial bacteria and reducing harmful ones like lactobacillus when present in high levels, which can correlate with metabolic disorders. This can assist in conditions like irritable bowel syndrome 2.
-
Caloric Restriction Benefits: While intermittent fasting sometimes overlaps with caloric restriction, it simplifies the process of reducing daily caloric intake and can offer weight maintenance benefits. For many, fasting is easier to manage than constant portion control 3 4.
-
Longevity and Cellular Repair: Fasting can trigger processes like autophagy, where cells remove dysfunctional components, potentially leading to longevity benefits and improved mental health due to better mitochondrial function 5.
-
Mental Clarity: Some people report a sense of increased mental clarity when fasting. Although neurons generally thrive on glucose, the fasted state can sometimes provide a different kind of mental sharpness 6.
These benefits, along with the findings from various studies, indicate that intermittent fasting can be a powerful tool for enhancing metabolic health, supporting gut health, and potentially extending lifespan, all while being a sustainable dietary practice for many people. However, it is important to note that individual experiences with fasting can vary, and it's essential to consider personal health conditions and consult with healthcare professionals.
