The Diet Doctor portal has become one of the most recognized platforms for nutritional education, with an emphasis on low-carb, ketogenic, and fasting strategies. Among its lead authors is Dr. Jason Fung, a Canadian nephrologist whose research and clinical practice have helped popularize intermittent fasting as a therapeutic tool.
Dr. Fung maintains that fasting activates cellular regeneration processes such as autophagy, a natural mechanism by which the body eliminates damaged or aged components. This process not only promotes internal detoxification but also contributes to the prevention of metabolic diseases related to obesity and insulin resistance.
Currently, lack of sleep and reduced quality of rest have created a situation in which the body's natural repair mechanisms are compromised. Fasting, by giving the digestive metabolism a break, allows the body to redirect energy toward cellular repair and cleansing processes, functioning as a complement to sleep in physiological restoration.
Dr. Fung's approach to Diet Doctor seeks to offer a framework based on scientific evidence and clinical experience with thousands of patients. His central message is that fasting should not be understood as extreme deprivation, but rather as a natural practice that can be safely adapted under supervision, and that is especially valuable in today's context of fast-paced lifestyles.
