Improve general health through intermittent fasting

The daily window of food intake, according to a recent study, has a significant impact on our life expectancy and on our general health. So-called intermittent fasting helps to live longer and healthier lives.

The latest study by Johns Hopkins University has now found that intermittent fasting can improve general health and also increase life expectancy. The results of the study were published in the English-language journal "New England Journal of Medicine".

What is intermittent fasting?

Intermittent fasting is a nutritional concept in which you only eat in a certain time window. All food should therefore be consumed within ten hours or less. Food should not be consumed for the remaining hours. Drinking water is of course allowed at any time.

Positive effects of intermittent fasting

Intermittent fasting can improve glucose regulation, blood pressure and heart rate. Intermittent fasting also appears to help with many health problems such as obesity, diabetes, cardiovascular disease, and cancer.

Five risk factors for metabolic syndrome

In the U.S., approximately 47 million people suffer from the so-called metabolic syndrome, a network of symptoms that is often preceded by diabetes. About one-third of US adults have at least three out of five risk factors that make up the metabolic syndrome: high blood sugar, high blood pressure, high triglycerides, low levels of HDL cholesterol, and abdominal obesity.

Protection against diabetes through fasting

About 85 percent of people who have these symptoms also suffer from type 2 diabetes. Anyone who suffers from both diseases has a far greater risk of developing a heart disease or a stroke. Intermittent fasting could reduce the risk of diabetes. Fasting can also increase stress resistance and suppress inflammation.

Does fasting protect brain health?

Preliminary studies also indicate that intermittent fasting could also benefit brain health, the researchers report. A study by the University of Toronto on 220 healthy, non-obese adults found that cognitive tests showed signs of improved memory through a two-year, reduced-calorie diet.

More research is needed

However, more research is needed to demonstrate the effects of intermittent fasting on learning and memory. If such evidence is found, fasting could help prevent neurodegeneration and dementia in the future.

Almost everyone can learn integrating fasting

Most people, with proper guidance and patience, could incorporate fasting into their lives. It should be noted, however, that the feeling of hunger and irritability initially appears quite often. These feelings usually subside after about two weeks to a month when your body and brain have become accustomed to the new circumstances. (as)
