Fasting is a practice where people choose not to eat for a certain period. This can be for religious, medical, or dietary reasons. Many religions, including Islam, Christianity, Judaism, Confucianism, and Hinduism, have traditions of fasting that have been followed for thousands of years. Even people who aren’t religious sometimes fast for health reasons.
Fasting means not eating for a set amount of time, usually between 8 to 12 hours. Interestingly, everyone fasts while they sleep, which is why the first meal of the day is called “breakfast”—because you are breaking your fast.
Fasting isn’t just a human practice; many animals do it too. Some animals eat only once a day or even less often. For example, cold-blooded animals like snakes can go days without eating, while warm-blooded animals like wolves usually eat daily. Humans can also fast for short periods without harm.
Short-term fasting, like going without food for a day, can have health benefits. Some studies suggest it might help people live longer, boost their immune systems, and improve brain function. A study in the journal Cell Stem Cell found that fasting for two to four days can help the body get rid of old immune cells and create new, healthy ones.
While short-term fasting can be beneficial, long-term fasting is more challenging. Our bodies store energy as fats and sugars, but these reserves need to be replenished regularly. After about 24-48 hours without food, the body starts using muscle and fat for energy. It’s also crucial to stay hydrated, as going without water for 72 hours can be dangerous.
When people fast, they might initially lose weight, but this is often just water weight that returns after eating. A study from Cornell University found that after fasting, people tend to crave high-calorie foods. However, it’s healthier to break a fast with vegetables, fruits, lean meats, and some carbohydrates.
Fasting can put stress on the body, but this isn’t always bad. Just like exercise stresses muscles to make them stronger, fasting can have positive effects when done correctly and combined with a balanced diet and exercise.
If you’ve tried fasting, consider sharing your experiences with others. It’s a great way to learn and connect with people who have similar interests.

Research the fasting practices of a specific religion or culture. Create a short presentation to share with the class, highlighting the reasons behind fasting, its historical significance, and any unique traditions associated with it.
Choose an animal that practices fasting in the wild. Create a poster or digital infographic that explains how and why this animal fasts, and how it benefits from this behavior. Share your findings with your classmates.
Conduct a simple experiment to understand the effects of fasting on energy levels. Track your energy and concentration levels over a day when you skip a meal (with parental permission). Record your observations and discuss them in a group to understand the short-term effects of fasting.
Plan a balanced meal to break a fast. Research the best foods to eat after fasting and create a menu that includes vegetables, fruits, lean proteins, and carbohydrates. Present your meal plan to the class and explain why you chose each item.
Participate in a class debate on the topic: “Is fasting beneficial for health?” Prepare arguments for both sides, considering the benefits and challenges of fasting. Engage in a respectful discussion with your peers to explore different perspectives.

Some religious groups require followers to fast for many hours a day, and some continue that fast for days or weeks. Is fasting for 16 hours a day every day dangerous?
Hello everyone, and welcome to DNews. I’m Trace. The Holy Month of Ramadan is wrapping up this week, and those Muslims who have been fasting for 15 hours a day or more will soon be able to enjoy food again. It’s not just Muslims who fast; Christians, Jews, Confucians, Hindus, and other religions have practiced fasting for thousands of years. Non-religious individuals also fast, often for medical or dietary reasons.
For some, the idea of abstaining from food during daylight hours seems unfathomable, and they may feel it’s unsafe. So, let’s explore some common fasting myths. A person is considered to be “fasting” if they have abstained from food for 8-12 hours. In fact, most people fast every night and break their fast in the morning, which is where the term “breakfast” comes from.
Fasting is a normal part of life for many animals on Earth. Many organisms eat only once a day or less, especially those that consume high-calorie foods like meat. Cold-blooded carnivores, such as snakes, can go days between meals, while warm-blooded carnivores, like wolves or coyotes, typically hunt daily. Humans, like coyotes, are also capable of fasting for short periods. A day or so without food isn’t harmful, and some studies suggest that short-term fasting can extend lifespan, boost immunity, and enhance mental function.
A recent study published in *Cell Stem Cell* found that fasting for two to four days can reduce white blood cells, which is beneficial. The older or damaged immune cells are eliminated, and when the body rebounds, it generates new, healthy cells using stem cells.
Long-term fasting, however, presents different challenges. When humans fast, our bodies follow a predictable pattern. Our bodies store energy in the form of fats and sugars, but ideally, we should eat every day or so to replenish those reserves. After 24-48 hours of fasting, glycogen reserves in the liver and muscles are depleted. After two days, the body begins to break down muscle and fat tissues for energy.
Water is also crucial; going 72 hours without water can be dangerous, so while short-term food fasting can be manageable, prolonged fasting without water can lead to dehydration.
Some may be curious about fasting diets, but it’s important to note that when you fast, you initially lose weight, primarily water weight, which will return once you eat again. Researchers at Cornell studied college students who fasted for 18 hours and then offered them a buffet-style meal. The most popular foods were high in calories, carbohydrates, and starches, as our bodies instinctively crave these to prepare for potential long-term starvation.
However, it’s important to remember that you know you will eat again. Ideally, after a fast, one should consume vegetables and fruits, with lean meats and some carbohydrates as part of the meal, but not the main focus.
Fasting can put stress on the body, but low-level stress can be beneficial, similar to how exercise strengthens muscles. Fasting is not inherently dangerous or deadly when done properly and in conjunction with a healthy diet and exercise.
