Water fasting is a period when a person eats no food and drinks only water. Fasting in this way may help with weight loss, but is it safe, and do the effects last long-term?


People may undertake water fasting to lose weight, for spiritual or religious reasons, or to try and combat particular health problems. Research suggests that occasional fasting may help with weight loss, although other methods may be more effective long-term.


To make sure that water fasting is done safely, people should prepare properly and choose a good time to go without food, when the body does not require too much energy.


What is water fasting?

A water fast is when a person does not eat and drinks nothing other than water.


There is no set time that water fasting should last for, but medical advice generally suggests anywhere from 24 hours to 3 days as the maximum time to go without food.


Throughout history, people have undertaken fasts for spiritual or religious reasons. But, water fasting is now popular in the natural health and wellness movements, often alongside meditation.

Benefit of water fasting

People with risk factors for certain diseases could benefit from short-term fasting. These include:


heart disease

high blood pressure

high cholesterol


being overweight

These risks are often related. When the body does not have access to carbohydrates, which are its preferred source of energy, it will use fats. So, a fast can result in weight loss as the body uses up fats in the body for its energy.


According to the Academy of Nutrition and Dietetics, the best way to lose weight is to take it slowly, combining a healthy diet with exercise. It is also important to try and change some eating habits, such as reducing the number of sugary foods and snacks eaten.


Although there are potential health benefits to fasting, there are considerable risks if a fast is carried out for too long, or by someone whose health or age puts them at risk of damage to their body.


If someone has health concerns, or is planning to fast for longer than 24 hours, they should seek the advice of a medical professional and consider undertaking a fast under supervision.
