What Science Says about the Health Benefits of Fasting
Written by Zalfa Imani Trijatna
In the month of Ramadan, millions of Muslims worldwide observe a strict daily fast from dawn to sunset. Although Ramadan fasting is arguably the most common, it’s important to note that everyone can also do other kinds of fasting.
Fasting may be challenging for some people. Of course, holding ourselves back from eating and drinking for extended hours can be tremendously difficult. However, despite its challenges, fasting has been scientifically proven to have numerous health benefits. Whether you’re fasting for religious or lifestyle reasons, here are 5 benefits of fasting for your health as backed by science that you should know.
Improves blood sugar control
According to Healthline, several studies have found that fasting may improve blood sugar control. A 2014 study found that fasting could reduce insulin resistance as much as limiting calorie intake. These studies indicate how fasting can be particularly beneficial for those at risk of diabetes.
Additionally, fasting can help you maintain your blood sugar levels, preventing spikes and crashes. This may result from the increased body’s sensitivity to insulin, which allows it to transport glucose from your bloodstream to your cells more efficiently, which is coupled with the possible blood sugar-lowering effects of fasting.
Fights inflammation
Inflammation is a normal immune process used by your body to fight infections, but it’s only if the inflammation is acute. In contrast, chronic inflammation may have severe consequences for your health, contributing to the development of chronic conditions, including heart disease, cancer, and rheumatoid arthritis.
As quoted from Healthline, some studies have found that fasting can help decrease levels of inflammation in your body. This also means that fasting may promote better overall health.
Promotes brain function
The impacts of fasting on brain function have been studied in humans and animals. The National Library of Medicine found that fasting improves cognition, stalls age-related cognitive decline, and reduces brain damage in animal models. In both animals and humans, fasting prevents and treats metabolic syndrome, which is a major risk factor for many neurological diseases.
Studies have also shown that fasting may help relieve the adverse effects of chemotherapy and protect cells from chemotherapy in cancer patients. The current results are indeed promising, but future research on the impacts of fasting on human brain health should still be developed further.

Helps lose weight
In previous Ramadans, you probably noticed changes in your weight. This is a common phenomenon in the global muslim community. Many people who fast during Ramadan may lose weight simply because there is a change in their portion sizes. According to Al Arabiya News, fasting for an extended period of the day can cause your stomach to become smaller and therefore hold less food.
However, keep in mind that the effects of Ramadan fasting on weight may vary between individuals. In other words, while some people lose weight, others may gain weight. As stated by the National Library of Medicine, this depends on whether or not energy intake in the non-fasting period under-compensates or overcompensates for the lack of energy intake during the fasting period. So, if you want to lose weight during the holy month, make sure you don’t overeat after breaking your fast and exercise regularly to lose weight more significantly.
Enhances heart health
As the leading cause of death around the world, heart disease accounts for an estimated 31.5% of deaths globally. One of the most effective ways to reduce your risk of heart disease is by making changes to your diet and lifestyle.
If you wish to make some diet and lifestyle changes, fasting may be ideal for you. Some research found that it can be especially beneficial for heart health. Studies have revealed that fasting could reduce cholesterol levels, blood pressure, and weight, which are all major risk factors for heart disease.
