Intermittent fasting (IF) is a popular eating pattern that cycles between periods of fasting and eating. It is not a specific diet but rather an eating schedule. There are many different intermittent fasting protocols, but the most common ones involve fasting for 16-20 hours per day and eating within a 4-8 hour window.
IF has been shown to have a number of health benefits, including weight loss, improved insulin sensitivity, reduced inflammation, and increased longevity. It can also be a helpful tool for managing chronic health conditions such as type 2 diabetes and heart disease.
How does intermittent fasting work?
When you fast, your body goes into a metabolic state called ketosis. In ketosis, your body burns fat for energy instead of glucose. This can lead to weight loss and improved insulin sensitivity.
IF also has a number of other health benefits, including:
- Reduced inflammation: Inflammation is a root cause of many chronic diseases. IF has been shown to reduce inflammation throughout the body.
- Increased longevity: Studies have shown that IF can extend lifespan in both animals and humans.
- Improved brain function: IF has been shown to improve cognitive function and protect against neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
- Reduced risk of chronic diseases: IF has been shown to reduce the risk of a number of chronic diseases, including type 2 diabetes, heart disease, and cancer.
