30 Day Water Fast for Weight Loss

30 Day Water Fast – Overview

Have you been trying to lose weight for the longest time possible without success? Are you overweight and have spent almost a decade setting weight loss as a new years’ goal?

Well, you are not alone. Many obese people are trapped by the grips of binge eating so tightly that even treatment centers have given up on them.

People take different approaches to detoxify their bodies, lose weight and improve their health. One of those approaches is the 30-day water fast.

Water fasting that is closely monitored by a health practitioner could be beneficial.

However, unsupervised water fast could severely affect your health, especially if it is attempted without medical guidance, especially among people with certain medical conditions.

This article will discuss what water fasting is and how it should be done. Read on to the end to find out what you should know before you try it out.

How to Do a 30 Day Water Fast

A water fast is a weight loss and body cleansing method that restricts the consumption of any food or drink apart from water for some time.

Typically, water fast lasts between 24-72 hours. However, it can last longer than 30 days. A medical practitioner should supervise a water fast that lasts longer than 72 hours.

You should prepare your body for going without food to prevent constipating during or after the fast.

Before the fast, eat some fresh vegetables and fruit juice, raw vegetables and fruits, and oatmeal.

Take fewer portions of food in the days preceding the fast. The foods should have a low content of sugar and fat.

While undertaking thirty-day water fast, you should never go two days without taking water as you might end up being dehydrated.

It would be best if you drink plenty of distilled water. Avoid tap water because it may have impurities that may cause ill health.

If possible, drink purified water as much as half of your body weight per day.

When on water fast, most people often feel a strong urge to eat junk. It is recommended that you abstain from caffeinated and sugary drinks such as diet drinks.

You should also avoid foods with high soy protein content, which often cause severe health problems during and after a fast.

 Areas of the Body Detoxified with a Water Fast

As you have 30 days of water fast, your body will undergo a process of detoxification in which four major organs will be cleansed: the large intestines, the skin, kidneys, and the lungs.

The Large Intestines- During the 30 days fast, having an enema before you go to bed could help you eliminate solid waste products from your colon, which makes your body sluggish, and causes headaches during the fast.

The significant intestine detox should be undertaken regularly throughout the rest of the water fast. A water fast deposits toxins into the intestines.

Failing to take an enema could lead to the reabsorption of these toxins into the bloodstream which could make you will feel quite nauseous.

The Kidneys- Drinking pure water eliminates all toxins in the body through the kidneys.

The Lungs- It is recommended that you walk for about half an hour every day if you are strong enough. Walking cleanses the lungs through deep breathing.

The Skin- Over half of the waste products in the body are eliminated through the skin.  Therefore, it is essential to bathe adequately using a loofah sponge or a bristle brush to help dislodge the dirt when bathing.

While undertaking 30-day water fast, you might experience a bit of discomfort on the second day, primarily due to the processes of detoxification.

Some of the issues you may experience include fleeting hunger pains and dizziness caused by withdrawal from caffeine, and sugar may cause headaches, but it is a part of the detoxification process.

Physical annoyances may also include weariness, tiredness, nausea, and sleepiness.

How to Successfully Break a 30 Day Water Fast

This time is as important as the beginning of a fast. You should carefully watch you eat for the first couple of days before you resume your regular diet.

You can begin breaking your fast with fruits such as shredded apples, pounded grapes, and steamed vegetables.

30 Day Water Fast – Breaking the Water Fast

There is no duration identified as the best period for breaking a fast. However, it is recommended that you extend your duration of breaking a fast by one day for every four days.

So if you were fasting for twelve days, you should break your fast in three days.

Avoid consuming heavy meals after a fast—heavy metals such as those high levels of proteins, for example, meat. Eating heavy meals after a fast could affect your digestive system permanently.

It could also cause complications like overstretching due to overeating. It would be best to continue taking water and fresh fruits and vegetable juices to allow the body to detoxify completely.

After taking fruits and vegetables on the first, second, and third day, increase the portions and begin including other types of meals slowly. You could, for example, have mashed potatoes without butter and later on have a salad without the oil dressing.

Training your stomach to eat lightly will prevent it from relapsing back to old habits.

Training your stomach to eat lightly will enable it to adjust accordingly and help you control and maintain your weight in the future.  

It is good to avoid bananas during the first days of breakfast because they have no juice and can easily cause constipation.

Also, do not break the water fast immediately. Begin by reducing the amount of water you take and increasing the amount of vegetable and fruit juice you take.


When it comes to diet and weight loss, there is no one-size fit method. Before embarking on a 30-day water fast, you need to discuss your health with a registered dietitian or doctor.

The health practitioner can then individualize the diet and detox plan to fit your body and health needs.
