The 60-Hour Fast Benefits and Results: Is It Safe?
  • A 60-hour fast is an extended fasting period lasting two and a half days.
  • Rules include avoiding calorie consumption, except for non-caloric drinks like water and herbal tea.
  • Goals include promoting autophagy, weight loss, improving insulin sensitivity, enhancing mental clarity, and resetting unhealthy eating habits.
  • Comparisons with other fasting methods reveal the potential benefits of a 60-hour fast.
  • Benefits include weight loss, improved insulin sensitivity, mental clarity, and reduced inflammation and heart disease risk.
  • A 60-hour fast can cause potential side effects like hunger, insomnia, dizziness, fatigue, and exhaustion.

What Is a 60-Hour Fast?

A 60-hour fast is an extended fasting period that lasts for a continuous two and a half days. During these 60 hours, you need to avoid calories coming from foods and drinks.

Many people follow prolonged fasting to lose weight or gain health-related benefits. Let’s learn about the specific rules and goals of a 60-hour fast.


  • Consume No Calories During Fasting: You need to avoid consuming any calories, including food, sugary drinks, or beverages like juice, milk, or regular soda.
  • Drink Water and Non-Caloric Drinks: Although you can’t consume calories, you can drink non-caloric drinks, including water, black coffee, herbal tea, and unsweetened electrolyte drinks, to stay hydrated and manage hunger.
  • Keep Electrolytes Balanced: To keep the electrolytes (sodium, potassium, and magnesium) balanced during prolonged fasting, you can consume supplements or foods like broth or bouillon.
  • Monitor Your Body’s Changes: Monitor how your body reacts to the changes happening during fasting and adjust your approach accordingly. If you feel extreme discomfort, dizziness, or other serious symptoms, break the fast and seek medical help.


  • Autophagy: Extended fasting can streamline autophagy, a process where the body cleans cells from damaged or dysfunctional cellular components. It is good because it helps longevity and prevents some diseases.
  • Weight Loss: Fasting, especially prolonged, can create a calorie deficit, which helps the body burn stored fat to provide energy.
  • Insulin Sensitivity: Fasting can regulate blood sugar levels by improving insulin sensitivity, which is good news for those having insulin resistance or type 2 diabetes.
  • Mental Clarity: A 60-hour fast can increase mental clarity and focus in some individuals.
  • Resetting Eating Patterns: A 60-hour fast is long enough to enable you to break unhealthy eating patterns and cravings and improve dietary choices.

What Is a 60-Hour Water Fast?

A 60-hour water fast is like a regular 60-hour fast, but it also bans all drinks except water together with calories during fasting, i.e., no calories and no drinks, but water. The logic behind excluding beverages is to reduce water weight, which is good for some athletes or people who need quick weight loss.

As you may think, a 60-hour water fast is a challenging approach and is not recommended for everyone. If you have certain goals and need to achieve them through a 60-hour water fast, you’d better consult a healthcare professional first to ensure it can’t hurt you.

A 60-hour water fast involves the same rules and goals as a 60-hour fast but is a bit more strict and is not a good way to start fasting for beginners.

Now that we’re comparing a 60-hour fast with similar approaches let’s compare it with two other extended fasting methods, i.e., a 48-hour fast and a 72-hour fast, to see which one can be a better option for us to reach our goals.

60-Hour vs. 48-Hour Fast

A 60-hour fast and a 48-hour fast are both extended fasting periods, but their main difference is duration. Also, a 60-hour fast can provide more significant results.

  • Duration: A 60-hour fast lasts 2.5 days, while a 48-hour fast lasts two complete days.
  • Benefits: Both fasting methods create autophagy and help weight loss. However, a 60-hour fast may bring better results due to being longer and keeping the body in the proper situation for longer.
  • Challenges: Both methods are challenging, especially for beginners, and cause hunger, dizziness, and discomfort. But a 60-hour fast can be more challenging for being longer.
  • Safety: Both fasting approaches can be risky for those with underlying medical problems; then again, a 60-hour fast can be riskier.

As you’ve learned by now, a 60-hour fast is not so different from a 48-hour fast, but it can provide more significant results, whether positive or negative.

60-Hour vs. 72-Hour Fast

Different extended fasting approaches share the main features, but the longer the fasting, the more considerable the results.

  • Duration: A 60-hour fast lasts for 2.5 days, while a 72-hour fast continues for three whole days.
  • Benefits: Both fasting methods help weight loss, autophagy, and insulin sensitivity, yet the results of a 72-hour fast may be more sensible.
  • Challenges: Both fasting approaches can cause hunger and discomfort.
  • Safety: Both methods can be risky, especially for beginners or those who have special illnesses.

So, let’s focus on the 60-hour fast and explore its benefits and side effects in detail to find out if it’s an approach worth trying.

The Benefits of a 60-Hour Fast

  • Studies show that obesity and type 2 diabetes can lead to different types of cancer (source). A 2017 study found that four months of 24-hour fasting two or three times a week reduced the participants’ weights and waist sizes by about %17.8 and %11, respectively. Also, after two months of fasting, they didn’t need insulin treatment (source).
  • Different animal studies indicate that autophagy has positive effects on preventing cancer (source).
  • The findings of a 2018 study showed that fasting could positively affect the quality of life in people undergoing chemotherapy for breast or ovarian cancers. In this study, the participants tried a 60-hour fast about 36 hours before chemotherapy (source).
  • A study conducted in 2014 found that fasting for 2-4 days can protect stem cells against the adverse effects of chemotherapy on the immune system (source).
  • Inflammation is the cause of various chronic diseases, including arthritis, heart disease, cancer, and more. Intermittent fasting can decrease even and reverse chronic inflammation (source).
  • Insulin resistance, increased blood sugar, high levels of blood triglycerides, inflammation, and LDL cholesterol can cause heart disease. Luckily, a 60-hour fast can significantly decrease these risk factors (source).
  • A 60-hour fast can help lower body fat, which helps decrease cholesterol levels and blood pressure, improving mental health problems like depression (source).
Summary: Obesity and diabetes increase cancer risk. A 60-hour fast can reduce weight and insulin dependency and improve cancer treatment. It protects stem cells, fights inflammation, lowers heart disease risks, and enhances mental health.

How Much Weight Can You Lose on a 60-Hour Fast?

Various factors affect your weight loss, and when it comes to losing weight by fasting, your starting weight, body composition, metabolism, activity level, and how you break the fast play important roles.

Let’s see how these factors affect our weight loss to be able to do the math and adjust to get the best results from extended 60-hour fasting.

Water Weight

Minimizing or removing the carbohydrate intake in the early stages of fasting results in water weight loss. For every gram of stored carbohydrates (glycogen), the body holds onto several grams of water. During fasting, the body uses glycogen, which results in water loss. That’s why some people, especially athletes, go for a 60-hour water fast.

Calorie Deficit

Avoiding calories for 60 hours leads to a calorie deficit, which makes the body burn fat for energy. So, the extent of weight loss depends on the number of calories you can burn.

Fat Loss

The amount of fat you can lose during a 60-hour fast depends on your metabolic rate, activity level, and individual variations.


How you break the fast plays an important role in your weight loss. If you overeat or consume a lot of high-calorie, high-carbohydrate foods immediately after the fast, you may regain some weight. So, it’s recommended to break the fast with water and small, low-calorie meals.

But remember that weight loss should be a byproduct of fasting, and you must focus on health and well-being. To lose weight, you need a balanced diet and regular exercise, which help improve the fasting’s effects on weight loss.

How to Do a 60-Hour Fast?

  • Consult a Healthcare Professional: You must find out if extended fasting is good for you and if your body can handle it. So, take the necessary test to make sure it’s safe for you.
  • Plan Carefully: Start fasting when your schedule is not busy so you can have minimal physical activities and stress.
  • Drink Water Before Fasting: In the days before a 60-hour fast, drink plenty of water to avoid dehydration during fasting.
  • Have a Balanced Meal: Before you start your fast, have a nutritious meal containing protein, healthy fats, and fiber to help keep you full at the beginning of the fast.
  • Stay Hydrated While Fasting: Drink water during fasting to curb hunger and avoid dehydration. Drink 8-10 cups of water or more every day.
  • Maintain Electrolyte Balance: Drink electrolyte drinks or take electrolyte supplements to avoid electrolyte depletion, which causes muscle cramps and other issues.
  • Listen to Your Body: Monitor your body’s changes during fasting to see how you need to manage before, after, and while fasting to minimize negative effects and make the most of fasting.
  • Stay Busy: Try to do your favorite activities (those not containing intense physical activities) to keep your mind off fasting.
  • Break the Fast Slowly: Break the fast with small, easily digestible meals to let your digestive system adapt. You can start with bone broth, steamed vegetables, or a small salad with lean protein.
  • Don’t Overeat: Don’t let the hunger monster eat everything all at once! Start eating regular meals gradually, not right after the fast.
  • Start Eating Normally: Return to your regular eating habits, focusing on balanced and nutritious meals. Do not consume high-calorie or processed foods.
  • Monitor Your Body: Keep paying attention to your body’s reactions after fasting. Try to adjust and seek medical help if needed. It’s normal to experience some digestive problems.

Doing the fast safely is one part of the fasting process. The second phase is breaking the fast healthily. If you avoid food for 2.5 days and start eating things you shouldn’t after fasting, you may undo all the good things you’ve done!

How to Break a 60-Hour Fast?

Here is a step-by-step guide to breaking a 60-hour fast healthily.

  1. Start with Liquids:

Hydration is the first step. Begin with small sips of water, herbal tea, or unsweetened electrolyte drinks. You can also start by drinking warm bone broth. Whatever you drink, some sips will do. Don’t drink too much.

  1. Add Protein Smoothie:

After the first drink, you can use a high-quality protein powder (whey, plant-based, etc.) mixed with water or non-dairy milk (like almond milk). You can also add some leafy greens for added fiber and vitamins.

  1. Start Light Meals:

Gradually start eating small portions of easily digestible meals containing steamed vegetables, a small salad with lean protein (chicken, turkey, tofu), or cooked quinoa.

  1. Avoid High-Carb and Processed Foods:

Do not consume high-carbohydrate or processed foods right after breaking the fast, as they cause rapid spikes in blood sugar levels and digestive discomfort. It’s better to eat whole, unprocessed foods instead.

  1. Listen to Your Body:

Monitor your body’s reactions in each step, as each body reacts differently. If you experience any discomfort, bloating, or digestive issues, slow down or modify your food choices.

  1. Stay Hydrated:

Continue to drink water throughout the day after breaking the fast.

  1. Be Patient:

Your digestive system may need some time to adjust to eating again after a 60-hour fast. Be patient, and don’t expect to get back to your regular eating habits right after extended fasting.

  1. Avoid Heavy or Greasy Foods:

Do not consume heavy, greasy, or fried foods initially, as these are harder to digest and may lead to discomfort.

  • Quinoa
  • Avocado: In salads or smoothies
  • Nuts and Seeds

Foods to Avoid after a 60-Hour Fast

  • Highly Processed Foods: Foods high in refined sugars, artificial additives, and preservatives

  • Alcohol
  • Large Meals
  • Spicy Foods

60-Hour Fast and Autophagy

A 60-hour fast and avoiding calories and carbs can provide a suitable situation for autophagy, which is a cell-cleaning process. Autophagy is a normal bodily process of cleaning the body from damaged or dysfunctional cellular components.

Autophagy can lead to many health benefits, including

  • Cellular Repair,
  • Disease Prevention: Diseases like neurodegenerative diseases, cancer, and infections, and
  • Longevity.

The extent of autophagy matters. Its duration depends on your metabolism, activity level, and general health. Longer fasting, like a 60-hour fast, may provide more extended exposure to autophagy, enabling more significant cellular repair.

Is a 60-Hour Fast Healthy?

A 60-hour fast can be healthy for experienced faster and those who follow the rules and make their body ready for such an intense challenge. However, note that extended fasting, including a 60-hour fast, is not suitable for everyone. Let’s review some general points you need to consider before doing a 60-hour fast.

  • Fasting Is Not a Weight Loss Shortcut: While a 60-hour fast can lead to weight loss, it should not be considered a shortcut for quick weight loss. If you want sustainable weight management, you need long-term dietary and lifestyle changes.
