The Complete Guide to Dry Fasting

Updated on March 7, 2023

If you’re like most people, you’ve probably heard about fasting diets and their benefits, from weight loss to inflammation reduction. In fact, it has been a common practice among many religions and cultures for centuries.

But, while it’s true that a few studies have found that fasting can be effective, the research isn’t strong. One such fad diet claim is dry fasting, which involves cutting out water completely.

Regardless of its potential benefits, dry fasting is a risky practice because you’re not getting the water you need to stay hydrated. And dehydration can cause serious complications, including low blood sugar, headaches, and nausea.

Some individuals may also experience nutrient deficiencies or feel irritable when deprived of water and food. This is why it’s important to consult with a professional before starting a new diet.

What Is Dry Fasting?

A dry fast is going without food or water for an extended period of time. It’s a variation of intermittent fasting, which can be helpful for weight loss and health but can also have some side effects.

Some people do a dry fast during the month of Ramadan, an annual Muslim religious observance. This may help improve body weight, lipids, and blood sugar.

However, dry fasting can have a number of side effects, including fatigue and headaches. It can also cause you to feel weak and dizzy, which could affect your work or school performance.

How Does Dry Fasting Work?

Dry fasting has been practiced by various religions and has been seen to help people lose weight and improve their health. It is also thought to enhance self-discipline and improve spirituality.

During a dry fast, the body goes into an extremely stressful state, forcing the cells to get rid of all toxins that are present in them. This is why dry fasting results in a significant drop in inflammation, which can help prevent autoimmune diseases, diabetes, and cancer.

The body is also forced to speed up metabolism to find energy sources, and it is believed that the secretion of hormones, such as PTH, helps in balancing cholesterol levels during this period.

It can be done safely as long as you follow a proper plan. It is best to start with intermittent fasting as it will help you to know your limits. You also need to follow this diet under the guidance of a professional.

The Best Way to Prepare for Dry Fasting

The best way to prepare for dry fasting is to drink plenty of water before you begin. Here are the three things you can do in order to prepare for a dry fast.

Talk To Your Healthcare Provider

If you’re interested in dry fasting, you may want to talk to your healthcare provider about the best way to prepare. Your preparation will depend on the type of dry fast you’re doing and how long it lasts. Prolonged dry fasting, or going without water and food for more than 24 hours, isn’t safe and should be avoided. 

Get Comfy With Intermittent Fasting

The best way to prepare for dry fasting is to start with intermittent fasting. This type of diet is less restrictive and allows you to drink water. Once you are comfortable with intermittent fasting, you can try dry fasting. 

Make Sure You Are Hydrated

Water is a must while fasting, and you should drink plenty of it outside the fasting window. Keep a bottle of water handy, and try to sip water in small amounts at short intervals. This will help you stay hydrated until the time comes for fasting. You should also eat lots of fruits and vegetables that have high water content.

How Long Should You Dry Fast?

A dry fast is a period of time when you are not eating or drinking any food or water. You can choose to dry fast for an hour, a day, or more. It’s a popular practice among Muslims during Ramadan. 

However, make sure you don’t fast for more than 8 to 12 hours, as it can lead to dehydration and other health problems. 

Do not do a dry fast without a doctor’s advice, especially if you have any health concerns or medical conditions. Also, it is not ideal for pregnant women and those who are breastfeeding.

Health Benefits of Dry Fasting

Dry fasting is an extreme form of intermittent fasting. It involves not drinking water or eating for a specified amount of time. Here are some potential health benefits of dry fasting. 

Fat Loss

Dry fasting allows you to lose weight quickly as your body burns fat for energy instead of storing it. However, it is important to note that this process can lead to dehydration if you aren’t careful.

Better Blood Sugar

In many religious communities, such as the Mormons, dry fasting has been shown to help prevent the onset of diabetes. There is also evidence that dry fasting increases insulin sensitivity, which can lead to better blood sugar control.

Decreased Inflammation

One of the major health benefits of dry fasting is that it reduces chronic inflammation. Long-term inflammation is a common cause of many chronic diseases, including heart disease, diabetes, and arthritis.

Lower Cholesterol Levels

One of the most significant health benefits of dry fasting is the reduction in cholesterol levels. The best way to reap the lipid-lowering benefits of dry fasting is to combine it with a diet rich in healthy fats.

Improved Bone Health

Dry fasting can boost your immunity and help improve bone health. It helps rid the body of old, diseased cells and enables new stem cells to replace them.

Health Risks of Dry Fasting

Dry fasting involves abstaining from food and water for a set amount of time. It promises health benefits like weight loss. But it can also cause serious side effects. If you’re considering dry fasting, make sure you understand the risks before starting.

  • Nutrient Deficiencies
  • Dehydration
  • Hunger


There are many claims by Instagrammers and dietitians about the health benefits of dry fasting. However, this diet is extremely restrictive and not suitable for most people. There are a few risks with this practice, including dehydration and electrolyte imbalances. There is no reputable medical research supporting the claim that you need to avoid water while fasting. Dry fasting can be dangerous, so you should only try it under the supervision of a doctor or other health expert. If done incorrectly, you can end up dehydrated.
