2. Insulin: Insulin sensitivity improves and levels of insulin drop dramatically. Lower insulin levels make stored body fat more accessible.
3. Cellular repair: When fasted, your cells initiate cellular repair processes. This includes autophagy, where cells digest and take away old and dysfunctional proteins that build up inside cells.

Gene expression: There are changes within the function of genes associated with longevity and protection against diseases.

These changes in hormone levels, cell function, and organic phenomenon are liable for the health benefits of intermittent fasting.

• Inflammation: Some studies show reductions in markers of inflammation, a key driver of the many chronic diseases.
• Heart health: Intermittent fasting may reduce “bad” LDL cholesterol , blood triglycerides, inflammatory markers, blood glucose , and insulin resistance — all risk factors for heart condition .
• Cancer: Animal studies suggest that intermittent fasting may prevent cancer.
• Brain health: Intermittent fasting increases the brain hormone BDNF and should aid the expansion of latest nerve cells. it's going to also protect against Alzheimer’s disease.
• Anti-aging: Intermittent fasting can extend lifespan in rats. Studies showed that fasted rats lived 36–83% longer.
