Fasting as a Therapeutic Option for Weight Loss
1.25 CEU Credit
U.S. dietary guidelines released in 1977 and the food pyramid of the 1980s cautioned Americans to restrict dietary fat and encouraged the regular consumption of grain by positioning it as the foundation of the diet. These recommendations corresponded with the rise of the obesity and Type 2 diabetes epidemics. Understanding the hormonal mediators (e.g., ghrelin and insulin) of hunger and food storage is vital to understanding the physiology of feeding, fasting, and changes in body fat mass. Caloric restriction increases hunger hormones and decreases metabolism. Fasting decreases hunger hormones, increases metabolism, and decreases insulin levels. Refined carbohydrate consumption and frequent eating increase insulin levels. Therapeutic fasting is highly effective for regulating and improving metabolic health, but it is not profitable for the medical industry. Prescription drugs and surgical interventions are very profitable although minimally effective.
Fasting is an ancient dietary strategy that carries important benefits for weight loss, Type 2 diabetes, and other chronic diseases. Here, Dr. Jason Fung discusses the physiology of fasting and how to apply it in a clinical setting.
Dr. Jason Fung, MD, is a nephrologist and expert in the use of intermittent fasting and low-carbohydrate diets for the treatment of Type 2 diabetes. He trained in Los Angeles and Toronto as a kidney specialist. Early in his medical career, it became obvious to him that conventional treatments were failing patients. Many of today’s medical issues are related to obesity, and without addressing the root cause, the other problems do not improve.
Following core physiologic principles, he founded the Intensive Dietary Management Program to provide a unique treatment focus for Type 2 diabetes and obesity: Rather than focusing on medications, this clinic focuses on dietary changes that are simple yet effective. He pioneered the clinical use of therapeutic fasting for weight loss and Type 2 diabetes reversal.
Fung is the author of The Obesity Code, The Complete Guide to Fasting and The Diabetes Code. He is also the scientific editor of the Journal of Insulin Resistance and the managing director of the Public Health Collaboration (Canada), an international nonprofit organization dedicated to promoting evidence-based nutritional information.
1. Develop a historical understanding of how dietary guidelines promoted eating patterns that may be detrimental to metabolic health.
2. Understand the hormonal mechanisms related to the physiology of feeding and fasting.
3. Understand why long-term weight loss is so difficult and learn how to apply therapeutic fasting in a clinical setting.
