Health Benefits of Intermittent Fasting

What is intermittent fasting? Intermittent fasting is considered a healthy lifestyle choice by many because it promotes autophagy, a cellular cleanup process. It can also promote the elimination of damaged cells, which,, in the long run, helps prevent the development of diseases such as cancer and Alzheimer’s. The health benefits of Intermittent fasting include:

  1. Promoting Weight Loss: Intermittent fasting helps the body burn fat for energy by decreasing insulin levels. This lowers the body’s glucose level and promotes fat storage to burn for energy.
  2. Improve insulin sensitivity: Intermittent fasting can lower insulin levels, leading to increased insulin sensitivity.
  3. Boosting brain function: Fasting is believed to increase brain function by stimulating the production of brain-derived neurotrophic factor (BDNF), which promotes the growth of new brain cells and protects existing ones.
  4. Lower inflammation: Inflammation can lead to various chronic diseases such as heart disease, cancer, and diabetes. Intermittent fasting helps reduce inflammation, which can lead to better overall health.

Risks of Intermittent Fasting

Intermittent fasting is not suitable for everyone as it may have some risks and side effects. Some of the risks include:

  1. Hunger: During the fasting period, hunger may be experienced, which can be uncomfortable.
  2. Dehydration: Many people forget to drink enough water during the fasting period, leading to dehydration.
  3. Headaches: Headaches are a common side effect of intermittent fasting, especially for beginners.
  4. Overeating: Overeating can occur when the eating window opens, leading to weight gain instead of weight loss.
