What is Intermittent Fasting?
Intermittent fasting is a pattern of eating that involves alternating between periods of fasting and periods of eating. There are several different methods of intermittent fasting, but the most popular ones are:
16/8 method: The 5:2 diet involves eating normally for five days and restricting calorie intake to 500-600 calories on two non-consecutive days. For example, a person may choose to eat normally from Monday to Friday and then restrict calorie intake on Saturday and Tuesday.
5:2 diet: The 5:2 diet involves eating normally for five days and restricting calorie intake to 500-600 calories on two non-consecutive days. For example, a person may choose to eat normally from Monday to Friday and then restrict calorie intake on Saturday and Tuesday.
Alternate-day fasting: Alternate-day fasting involves fasting every other day and eating normally on non-fasting days. For example, a person may choose to fast on Monday, eat normally on Tuesday, fast on Wednesday, and so on. During the fasting period, no food or calorie-containing beverages are consumed, but water, coffee, and tea are generally allowed. The purpose of intermittent fasting is to create a calorie deficit, which can lead to weight loss and other health benefits.
How Does Intermittent Fasting Affect Your Body?
Intermittent fasting has been shown to have several positive effects on the body, including:
Weight Loss: One of the most significant benefits of intermittent fasting is weight loss. By creating a calorie deficit, the body starts to burn stored fat for energy, which leads to weight loss. The 16/8 method is an excellent example of this. By fasting for 16 hours and eating within an 8-hour window, the body has fewer hours to consume food, which can reduce overall calorie intake.
Improved Insulin Sensitivity: Intermittent fasting has been shown to improve insulin sensitivity, which is the body's ability to use insulin effectively. When we eat, our body releases insulin to help transport glucose into cells for energy. However, over time, the body can become resistant to insulin, leading to high blood sugar levels and type 2 diabetes. By improving insulin sensitivity, the body can use insulin more efficiently, reducing the risk of type 2 diabetes.
Reduced Inflammation: Chronic inflammation is a risk factor for many chronic diseases, including heart disease, cancer, and Alzheimer's disease. Intermittent fasting has been shown to reduce inflammation in the body, which can reduce the risk of these diseases.
Increased Autophagy: Autophagy is a natural process in the body that removes damaged cells and debris. Intermittent fasting has been shown to increase autophagy, which can have anti-ageing benefits. By removing damaged cells, the body can regenerate healthy cells, leading to improved overall health and longevity.
Improved Brain Function: Intermittent fasting has been shown to improve brain function and protect against neurodegenerative diseases like Alzheimer's and Parkinson's disease. During periods of fasting, the body increases the production of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and survival of brain cells.
