Intermittent fasting involves cycling between periods of eating and fasting. Common methods include the 16/8 method or the 5:2 method
During fasting, the body may enter a state called autophagy, where cells remove and recycle old components. This process is thought to have various health benefits, including cellular repair and improved longevity.
Intermittent fasting can be effective for weight loss due to the restriction of the eating window, which naturally reduces overall calorie intake. Additionally, fasting periods may enhance fat burning for energy.
Intermittent fasting may improve insulin sensitivity, helping regulate blood sugar levels. This can be particularly beneficial for individuals at risk of or managing type 2 diabetes.
The process of autophagy, stimulated during fasting, is associated with cellular repair and increased lifespan in some studies. However, more research is needed to fully understand these effects in humans.
Fasting can lead to changes in hormone levels, such as increased norepinephrine and human growth hormone (HGH), which play roles in fat metabolism and muscle preservation.
Some studies suggest that intermittent fasting may have benefits for heart health, including improved cholesterol levels, reduced blood pressure, and a lower risk of heart disease.
