Researchers from the University of Illinois Chicago suggest that water fasts may not be an effective method for sustained weight loss. While water fasting can lead to short-term weight loss, it is uncertain how long the weight will stay off once solid foods are reintroduced.
Additionally, the metabolic benefits like lower blood pressure and improved cholesterol from water fasting seem to diminish quickly after the fast ends. The study found no significant negative effects of water fasting or similar low-calorie fasts.
According to Krista Varady, a professor of kinesiology and nutrition at UIC and the project’s leader, water fasting may require significant effort and does not offer long-term metabolic benefits. However, it is crucial to maintain hydration, especially in hot weather.
Professor Varady said that it is crucial to have medical supervision if attempting a fast for more than five days. She is an expert in intermittent fasting and conducted a study on water fasting due to inquiries from journalists.
The report summarizes eight studies that examine the effectiveness of water fasting and Buchinger fasting, a supervised fast popular in Europe. The studies analyzed by Prof. Varady and her team aimed to determine the efficacy of these approaches for weight loss and various metabolic factors.
Staying hydrated is crucial during water fasting for weight loss. The YETI Tundra Haul Portable Wheeled Cooler is recommended to keep water cool in hot conditions. The cooler is praised for its durability and functionality, making it an ideal option for maintaining hydration during fasting.
Fasting demonstrated significant results in terms of temporary weight reduction. Individuals who engaged in a five-day fasting regimen experienced a weight loss of approximately four to six percent. Likewise, those who fasted for a period of seven to 10 days observed a weight reduction ranging from two to 10 percent, while participants fasting for 15 to 20 days achieved a weight loss of seven to 10%.
