“The Obesity Code:Unlocking the Secrets of Weight Loss” by Jason Fung, MD.
This book lays out the root cause of obesity and diabetes is hyperinsulinemia and insulin resistance, and the cure is reducing overall endogenous insulin production/secretion through manipulation of:
When to eat—practice of intermittent fasting.
What to eat—whole foods rather than processed foods.
Avoid insulin spiking foods i.e. sugars, processed carbohydrates, and even protein.
Dr. Jason Fung completed medical school at the University of Toronto and a fellowship in nephrology at the University of California. He founded the Intensive Dietary Management Program in Toronto that provides a unique treatment focus for type 2 diabetes and obesity. Dr. Fung lives in Toronto.
Important Note About This Study Guide
This guide is a summary and not a critique or a review of the book. It does not offer judgment or opinion on the content of the book. This summary may not be organized chapter-wise but is an overview of the main ideas, viewpoints, and arguments from the book. It is NOT meant to be read as a replacement of the book which it summarizes but, instead, a supplement for review of the book's main premises and to provide commentary and additional resources.
What Causes Obesity?
The authorities and experts say it is a matter of Calories In versus Calories Out. Their advice is: "Eat Less, Move More." For over forty years, doctors have recommended a low-fat, calorie-reduced diet as the treatment of choice for obesity. Yet the obesity epidemic accelerates. The prevalence of obesity among American adults more than doubled since the early 1960s, from 13.4 percent to 35.7 percent.
Most "Eat Less, Move More" programs failed to achieve long-term weight loss because "calorie in versus calorie out" is not the only factor that causes obesity. Obesity is a multifactorial disease. We need a coherent theory to understand how all its factors fit together.
This book provides one such coherent framework that can account for most of what we know about the real causes of obesity. Obesity is preventable and potentially reversible if you understand their biological causes—not just their symptoms.
Part 1 of this book explores the environmental and genetic factors that give insight into the underlying causes of the obesity epidemic.
Part 2 reviews the current caloric reduction theory in depth, showing the shortcomings of the current understanding of obesity.
Part 3 introduces the hormonal theory of obesity to explain the central role of insulin and insulin resistance in regulating body weight.
Part 4 uses the hormonal theory of obesity to explain the social phenomenon of obesity.
Part 5 explores the roles of fat, protein, and carbohydrates in weight gain.
Part 6 provides guidelines for lasting treatment of obesity by addressing the hormonal imbalance of high blood insulin.
HOW OBESITY BECAME AN EPIDEMIC
Foods comprise three macronutrients: fat, protein, and carbohydrates. Refined carbohydrates were known to be fattening since the early 1800s as the French scientist and physician Jean Anthelme Brillat-Savarin described in his 1825 textbook, The Physiology of Taste.
Four decades later, William Banting, an English undertaking, rediscovered that "fattening carbohydrates" caused weight gain. Banting was not an obese child, nor did he have a family history of obesity. But he gained weight in his mid-thirties. He started eating less and exercising more. His physical fitness improved, but he still failed to lose weight because the exercise had built up his appetite. At the advice of his doctor, Banting tried a new approach. He avoided all bread, milk, beer, sweets, and potatoes. Banting not only lost the weight and kept it off. He felt so well he published his findings in the famous pamphlet Letter on Corpulence in 1863. For most of the next century, a diet low in refined carbohydrates was the standard treatment for obesity.
THE DIETARY GUIDELINES
With the discovery of vaccines and antibiotics, combined with increased public sanitation, infectious diseases such as pneumonia, tuberculosis, and gastrointestinal infections, became curable. Heart disease and cancer now caused a relatively greater number of deaths.
In the 1950s, heart disease became the number one killer. Physicians advocated lower-fat diets because dietary fat was thought to increase the cholesterol in the blood causing heart disease. But there was one problem: lowering dietary fat meant replacing it with either protein or carbohydrate. Since many high-protein foods are also high in fat, one must increase dietary carbohydrates.
In 1977, the United States Senate Select Committee on Nutrition and Human Needs issued a set of nutritional guidelines titled Dietary Goals for the United States. The specific guidelines include:
Increase consumption of carbohydrates until they reached 55 to 60 percent of calories; and
Decrease fat consumption to 30 percent, of which only one-third should come from saturated fat.
Although the guidelines still recognized the evils of sugar, refined grain was innocent.
The Dietary Guidelines for Americans, now updated every five years, were followed by the entire nation and the rest of the world. It created the infamous food pyramid
