What is a 24-hour fast?
A 24-hour fast, also known as a 24-hour intermittent fasting involves abstaining from food for a full day. While it might not be suitable for everyone, understanding the benefits of a 24-hour fast and the proper way to do it can make this fasting method a valuable tool in promoting overall health and well-being.
How to do a 24-hour fast
Starting a 24-hour fast might require some planning and preparation. Here’s a brief step-by-step guide to help you get started:
1) Choose a suitable time: Pick a day when you can comfortably manage a full day without eating. Consider your schedule and avoid days with high-stress events or strenuous activities.
2) Begin after dinner: Start your 24-hour fast after a regular dinner. This way, you can sleep through a significant portion of the fasting period, making it more manageable.
3) Stay hydrated: Throughout the fast, drink plenty of water to stay hydrated and support your body’s natural detoxification processes.
4) Avoid intense workouts: While light exercise is generally fine, avoid intense workouts during the fasting period to prevent overexertion.
5) Break the fast gently: When the 24 hours are up, reintroduce food gradually to avoid shocking your digestive system.
Benefits of a 24-hour fast
While the benefits of popular intermittent fasting plans such as the 14/10 or the 16/8 plans are now known to almost everyone, the benefits of such an extreme form of fasting remain a mystery. So it’s quite understandable for someone to ask “What does a 24-hour fast do?”
Let’s delve deep into what a 24-hour fast can offer:
Engaging in intermittent fasting for 24 hours can create a calorie deficit, potentially aiding in weight loss over time. But, sustainable weight management involves a balanced diet and regular exercise.
Improved insulin sensitivity
Fasting can help regulate insulin levels, leading to improved blood sugar control and reduced risk of type 2 diabetes.
Fasting can give your digestive system a break from constant processing, which may be beneficial for some individuals. However, those with a history of eating disorders or gastrointestinal issues should approach fasting with caution.
During long hours of fasting, your body initiates autophagy, a process that helps remove damaged cells and triggers cellular repair mechanisms.
Enhanced brain function
Some people report improved mental clarity and focus during fasting periods, which could be attributed to hormonal changes and increased production of brain-derived neurotrophic factor (BDNF).
Regular fasting may enhance the body’s ability to switch between burning glucose and fat for fuel, promoting metabolic flexibility.
Some studies suggest that intermittent fasting may improve heart health markers, such as cholesterol levels and blood pressure, potentially reducing the risk of cardiovascular diseases.
Reduction of oxidative stress
Fasting may reduce oxidative stress and inflammation in the body, contributing to overall health and longevity.
Research on animals has shown that intermittent fasting may extend lifespan, though more human studies are needed to confirm this effect.
What to eat after a 24-hour fast
As fasting for 24 hours means a very long time without getting any calories, breaking a 24-hour fast properly is crucial to prevent digestive issues and maximize the benefits.
When breaking a 24-hour fast, opt for nutrient-dense, easy-to-digest foods, such as fruits, vegetables, lean proteins, and whole grains. Avoid large, heavy meals and eat smaller portions spread throughout the day to ease your digestive system back into action.
How much weight can you lose in a 24-hour fast?
In a 24-hour fast, the amount of weight you may lose can vary depending on various factors, such as your:
- starting weight,
- activity level, and
- overall health.
It is essential to understand that a 24-hour fast primarily involves water weight loss and the depletion of glycogen stores rather than significant fat loss. During a fast, your body uses up its stored glycogen for energy. Glycogen is the stored form of carbohydrates in your liver and muscles, and it holds water. As glycogen is depleted, the water bound to it is released, resulting in a decrease in weight on the scale.
On average, you may lose around 1-2 pounds (0.45-0.9 kilograms) during a 24-hour fast, primarily due to this water weight loss.
So bear in mind that this weight loss is temporary and can be easily regained once you resume your regular eating habits. Fasting can be a helpful tool for some individuals as part of a balanced and healthy lifestyle, but it should not be seen as a quick fix for weight loss.
Is 24 hour fasting healthy?
The healthiness of a 24-hour fast largely depends on individual factors and how the fasting is approached. When done responsibly and with consideration of your overall health, a 24-hour fast can be safe and even offer potential health benefits.
On the other hand, fasting for extended periods without proper knowledge and preparation can lead to negative consequences, including:
- Nutritional deficiencies: Prolonged fasting can lead to nutrient deficiencies if not done properly, potentially impacting overall health.
- Hunger and discomfort: Fasting for an entire day can be challenging for some individuals, leading to excessive hunger, fatigue, or irritability.
- Impaired physical performance: Strenuous physical activities during fasting periods might lead to decreased performance and increased risk of injury.
- Unhealthy eating habits: Some people might overeat or make poor food choices when breaking the fast, negating any potential benefits.
So, it’s not possible to give an exact answer if fasting for 24 hours is healthy. A 24-hour fast can be a safe and healthy practice for some individuals, particularly when done mindfully and occasionally, but it may not be suitable for everyone. It’s essential to listen to your body and consult with a healthcare professional before attempting any fasting regimen, especially if you have underlying health conditions.

How often should you do a 24 hour fast?
While fasting can offer potential health benefits, doing it too frequently or without proper guidance may have adverse effects on some individuals. It is essential to consider your unique circumstances before deciding on the frequency of 24-hour fasts.
The frequency of 24-hour fasts depends on individual factors, such as:
- Individual health status: If you have any underlying health conditions or concerns, it is crucial to consult with a healthcare professional before incorporating 24-hour fasts into your routine. Certain medical conditions may require a different approach or could make fasting inadvisable.
- Personal goals: Consider your reasons for fasting. Are you trying to improve metabolic health, manage weight, or enhance mental clarity? Understanding your objectives can help determine the appropriate frequency of fasting.
- Experience with fasting: If you are new to fasting, it’s best to start gradually and not attempt 24-hour fasts too frequently. Give your body time to adapt and listen to how it responds.
- Your body’s response: Pay attention to how you feel during and after a 24-hour fast. If you experience excessive hunger, weakness, dizziness, or other adverse effects, it may be a sign that you need more time between fasting periods.
Benefits of 24-hour fast once a week
In general, for individuals without specific health concerns, doing a 24-hour fast once a week or once every two weeks may be a reasonable frequency. This allows for sufficient time to recover between fasting periods and may still offer some of the potential health benefits associated with intermittent fasting.
- Besides the usual benefits of intermittent fasting, practicing a 24-hour fast once a week encourages more mindful eating and a better connection with hunger and fullness cues.
- Once-a-week 24-hour fasting can also be more manageable for some people than daily fasting regimens.
Should you work out during a 24-hour fast?
Whether or not you should work out during a 24-hour fast depends on your individual health, fitness level, and how you feel during the fasting period. Engaging in exercise while fasting can be safe and even beneficial for some individuals, but it may not be suitable or comfortable for everyone.
Here are some considerations regarding working out during a 24-hour fast:
- Energy levels: Fasting can lead to reduced energy levels, especially if you are not accustomed to fasting or have specific health conditions. If you feel weak or fatigued during the fast, it may be best to avoid intense exercise.
- Hydration: Staying hydrated is crucial during fasting, especially if you plan to work out. Make sure to drink plenty of water before, during, and after the exercise session.
- Intensity and duration: If you decide to work out during a 24-hour fast, opt for moderate-intensity activities rather than high-intensity workouts. Shorter exercise sessions might be more appropriate to avoid overexertion.
- Recovery: Keep in mind that fasting itself is a form of stress on the body. Adding intense exercise on top of fasting can put additional stress on your system. Ensure that you have sufficient time for rest and recovery.
- Break the fast gently: If you plan to work out during a 24-hour fast, consider breaking the fast with a balanced meal that includes carbohydrates, protein, and healthy fats to support muscle recovery and replenish energy stores.
- Individual factors: Some people may feel energized and have positive experiences with exercising during a fast, while others may find it challenging or uncomfortable. It’s essential to consider your personal preferences and responses to exercise and fasting.
If you are new to fasting or exercise, it might be best to avoid intense workouts during fasting periods until you become more familiar with how your body responds to both practices.
To sum up
A 24-hour fast, when done correctly and in a healthy individual, can offer a range of benefits, from improved insulin sensitivity to enhanced cellular repair. However, it is essential to listen to your body and consult with a healthcare professional before embarking on any fasting regimen, especially if you have underlying health conditions.
Remember, fasting is not a one-size-fits-all approach, and what works for one person may not be suitable for another. If you decide to try a 24-hour fast, approach it with mindfulness and respect for your body’s needs, and enjoy the potential health benefits this powerful practice can offer when integrated sensibly into your lifestyle.
