Benefits of Fasting for 24 Hours And Its Risk Factors

The benefits of fasting for 24 hours have a lot. Because research suggests that occasional 24-hour fasting can improve cardiovascular health. Some evidence from research on animals shows that fasting can help fight certain kinds of cancer or even help preserve memory. Here we are going to discuss the benefits of fasting for 24 hours.

Many religious traditions, including the Jewish and Muslim observances of Yom Kippur and Ramadan, are long-term fasting fasts. A type of fasting sometimes known as fasting has also gained popularity as a weight-loss tool. Many studies have examined the benefits and risks of skipping meals for a day, including how it affects weight loss. In this article, we look at what happens to the body during fasting as well as what a person can do to secure fasting.

What happens during Ramadan?

Whether a person fasts or not, the body still needs energy. Its primary energy source is a sugar called glucose, which usually comes from carbohydrates, including grains, dairy foods, fruits, certain vegetables, beans, and sweets. The liver and muscles store glucose and release it into the bloodstream whenever the body needs it.

However, this process changes during fasting. After about 8 hours of fasting, the liver will make the last use of its glucose reserves. At this point, the body enters a state called gluconeogenesis, marking the body’s transition to fasting mode.

Studies have shown that gluconeogenesis increases the number of calories burned by the body. With no carbohydrates, the body makes its own glucose, mainly using fat. Eventually, the body goes beyond these energy sources as well. The fasting mode then turns into a more severe mode of starvation.

At this point, a person’s metabolism slows down and their body begins to burn muscle tissue for energy. Although it is a well-known term in dieting culture, true starvation mode occurs only after a few days of continuous or even a few weeks without food.

Thus, it is usually safe for those who are breaking their fast after 24 hours not to eat for one day unless they have other health conditions.

Benefits of Fasting for 24 Hours

Reduces the risk of heart disease

A new study by cardiac researchers at the Intermountain Medical Center Heart Institute has discovered that fasting for a short period of time may reduce the risk of heart disease and reduce cardiac risk factors such as triglycerides, weight, and blood sugar levels.

Reduces body fat

Another study found that regardless of your low-fat or high-fat diet, short-term fasting is associated with weight loss and increased fat oxidation.

Cleanses toxins

A third study found that short-term fasting takes the form of “nutritional hormesis,” where the body releases toxins and stress-related hormones.


Spending the whole day without eating teaches you how to control your emotions and not be easily tempted.


The motivation of hunger can lead to short-term development. Evolutionarily, hunger was a symptom that we needed to hunt or gather food, so our energy and focus experience temporarily increased when we became hungry.

I think there are some “tangible statues” behind this effect as well. For example, we often describe goals and successes in terms of “hunger” and “satisfaction”. One study suggested that hunger makes us a greater risk-taker, which I think is associated with this motivational drive when fasting.


You will realize how much you should be thankful every day without eating (because some people don’t have the luxury).

Can fasting promote weight loss?

It turns out that fasting can help with weight loss. However, studies make it clear that this is not the case for everyone. Popular diet plans include 12-hour or 16-hour fasting as well as 24-hour fasting. Some diets require people to drink only water during fasting, while others allow zero-calorie drinks.

Weight loss will be followed by fatigue and constant tiredness. A recent study found that obese people who fasted occasionally for 12 months lost slightly more weight than those who dieted in a more conventional way, but the results were not statistically significant. The limitations of fasting seem to be less related to its physical effects than to how it fits into a given lifestyle.

For example, the same study found that those who fasted were more likely to give up weight loss efforts than those who died using conventional methods, such as calorie counting. The researchers concluded that fasting may become more difficult over time.

Another potential concern is post-binge bing. Some fasting experts agree that it is easier to trade weight loss success by doing extra work after fasting. Fasting days can also provide a false sense of security, leading people to ignore positive eating habits on fasting days.

Other effects of Fasting

As well as helping with weight loss, there may be other health benefits to not eating for a day. Research suggests that occasional 24-hour fasting may improve cardiovascular health. Some evidence from animal studies shows that fasting can help fight certain types of cancer and even preserve memory.

Drinking water

Drinking plenty of water can help reduce the pain of hunger. It is essential to drink enough water to maintain daily health, whether a person is eating or not eating at all.

Many health authorities recommend drinking eight-ounce glasses (about 2 liters) of water per day. If a religious ceremony does not forbid it, a person can take the opportunity to fast by drinking plenty of water to help alleviate the suffering of hunger.

During the 24-hour fast, some people drink other beverages such as tea, black coffee, or zero-calorie sweetened beverages.

Risk of Fasting

Although it is generally safe, it can be risky to go without food for a day, including:

  • People with diabetes
  • People with a history of eating disorders
  • People use medications that they must take
  • Children and adolescents
  • Those who are pregnant or breastfeeding


Is fasting for 24 hours beneficial?

In general, most types of fasts are performed over 24–72 hours. Intermittent fasting, on the other hand, involves cycling between periods of eating and fasting, ranging from a few hours to a few days at a time. Fasting has been shown to have many health benefits, from increased weight loss to better brain function.

How often should you do a 24 hour fast?

What the 24 hour fast looks like: Once a week, fast for 24 hours. Once the fasting period passes, proceed with eating as if you had not fasted at all. While Eat Stop Eat suggests fasting 1-2 times per week, I'm not sure how sustainable two days of fasting in a week is for the average person.

What happens when you do a 24 hour fast?

After eight hours without eating, your body will begin to use stored fats for energy. Your body will continue to use stored fat to create energy throughout the remainder of your 24-hour fast. Fasts that last longer than 24 hours may lead your body to start converting stored proteins into energy.

Is it safe to fast 24 hours everyday?

The general medical consensus is that it's probably safe for most healthy adults to fast every once in a while. However, the studies noted here reference general intermittent fasting or days of water-only fasting. There are not many studies specifically on the risks or benefits of OMAD.

Is it better to fast for 24 or 36 hours?

The current study involved fasting for a total of 36 hours, a pretty long stretch to go without eating. But earlier evidence shows a less extreme version of intermittent fasting can help. A previous study published in 2013 examined the results of a shorter fasting period: 24 hours.
