Dr. Edward Group, DC, discusses the body’s self-healing mechanisms that are activated when we engage in different types of fasting, including Ketogenic diet, intermittent fasting, and the water-only fast. New studies confirm the age-old notion that fasting slow illness and disease by boosting the immune system. He explains that this can be somewhat controversial, as many practitioners are taught to only treat the symptoms rather than the cause, so these cleansing and fasting techniques are not being taught in medical schools.
