What is intermittent fasting?
Periodic fasting, also known as intermittent fasting, is a dietary method where you alternate between fasting and eating periods. There are different methods of intermittent fasting, but the most common is the 16:8 method, where you fast for 16 hours and have an eating window of 8 hours. This means that you can, for example, eat between 12 noon and 8 pm and fast the rest of the time.
Another method that has gained attention is the 14:10 method, where you fast for 14 hours and have an eating window of 10 hours. This method may be more accessible to those who do not want to skip breakfast, which may be an advantage for some.
Scientific support for intermittent fasting
There is a growing body of research supporting the health benefits of intermittent fasting. A study published in 2020 showed that intermittent fasting can contribute to weight loss and improved body composition, even without reducing calorie intake. This can be particularly interesting for those who want to lose weight and at the same time maintain muscle mass.
Another study showed that intermittent fasting can have a positive effect on heart health. The researchers found that intermittent fasting can help lower blood pressure, improve cholesterol levels and reduce the risk of cardiovascular disease. Intermittent fasting can also have a positive effect on blood sugar levels. A study conducted on people with prediabetes found that intermittent fasting can help stabilize blood sugar and improve insulin sensitivity.
The Four Benefits of Intermittent Fasting
Intermittent fasting has benefits such as weight loss, improved metabolic health, increased mental focus and energy, reduced inflammation, and potentially increased longevity. Below we go through some of the most popular reasons why people choose periodic fasting:
Weight loss and body composition
One of the main reasons many choose intermittent fasting is for its potential to aid in weight loss. By limiting eating periods, you can reduce total calorie intake and stimulate the body to use fat reserves as fuel. This can lead to weight loss and an improved body composition. Research has also shown that intermittent fasting can help maintain muscle mass during weight loss. This is important to avoid the body breaking down muscle instead of fat.
Improved heart health
Intermittent fasting can have positive effects on heart health by lowering blood pressure and improving cholesterol levels. By limiting eating periods, you can reduce the intake of harmful substances that can affect the heart negatively. Additionally, intermittent fasting can help reduce inflammation in the body, which is an important factor in heart health.
Better blood sugar control
Research has shown that intermittent fasting can help stabilize blood sugar and improve insulin sensitivity. By limiting eating periods and avoiding large blood sugar fluctuations, you can reduce the risk of insulin resistance and type 2 diabetes.
Calmer stomach and better digestion
Many people find that intermittent fasting can contribute to a calmer stomach and better digestion. By giving your stomach and intestines a longer time to rest between meals, you can reduce the risk of digestive problems such as gas, bloating and stomach aches. There is also research that suggests that intermittent fasting can have a positive effect on gut flora, which is important for healthy digestion and a strong immune system.
How to practice intermittent fasting
Intermittent fasting can be adaptable and there are different ways to practice it. Here are some tips for getting started with intermittent fasting: Choose a method that works for you: There are different methods of intermittent fasting, so choose one that fits your lifestyle and goals.
