Fasting has gained popularity as a weight loss and wellness practice, with some individuals opting to fast for extended periods, carefully managing their nutritional intake during specific time windows. While many people incorporate hydration into their fasting routines, a growing trend known as “dry fasting” has emerged, where people abstain from both food and water. However, experts caution that dry fasting can be harmful to the body.
According to nutritionist Shyla Cadogan, RD, in a recent article, the human body can survive without food for a certain amount of time, but water is essential. Depriving the body of hydration for extended periods can lead to several health complications. Cadogan emphasizes that dry fasting can increase the risk of dehydration, causing symptoms such as fatigue, reduced urine output, constipation, headaches, and a lack of concentration. While dry fasting may appear to result in weight loss, this is often just water weight, which is quickly regained once fluids are reintroduced.
For those on a weight loss journey, staying hydrated is crucial. Proper hydration supports joint lubrication, maintains water and electrolyte balance, regulates body temperature, and promotes healthy bowel movements. Cadogan also highlights that there are healthier ways to fast that do not involve the risks of dry fasting, urging people to avoid putting their bodies through unnecessary harm.
While certain religious observances, such as Ramadan, involve fasting, these practices typically allow for meals before sunrise and after sunset, providing sufficient hydration within a timeframe that the body can handle. However, adopting dry fasting for wellness purposes can lead to serious health issues, making it a risky trend.
