Nighttime Fasting: A Doctor Explains the Benefits and Importance of Individual Needs Spain, May 30, 2025 – Dr. Sari Arponen, a physician and researcher, recently appeared on Cadena SER's popular radio show, La Ventana, to discuss the health benefits of nighttime fasting. Her interview highlighted the importance of this practice for overall well-being and the need to consider individual factors. Dr. Arponen explained that for most healthy adults, a 12–13 hour overnight fast is ideal.
