The book I am going to introduce now was published in 2016. It is because a friend told me he read a book “Obesity Code” written by Dr. Jason Fung. He strongly recommended the book, and he insisted he lose more than 30 pounds by following Dr. Fung’s advice. I was quite sceptical but eventually bought the book. It was because I have tried many methods, including taking medicine, but none of the methods were successful. I read the book and follow the advice accordingly. I lost more than 40 pounds, and many of my relatives and friends suspect I have critical diseases or cancer.
How many pounds have you ever tried to lose weight? What methods have you used to lose weight? Did you succeed or fail in the end? Do you feel losing weight is difficult? Perhaps you have decreased your intake of food and still found it hard to lose a few pounds. But as long as you cannot bear it and eat a little more, your weight will bounce back and increase.
The Obesity Code By Dr. Jason Fung
This book is meaningful to me, because it can save my friend David’s life. David’s grandmother has diabetes, and before she passed away, she was obese and had severe diabetes conditions. David’s father was also very fat and had diabetes. The whole family has one thing in common, that is, they enjoy eating a lot. In fact, I was really happy to have dinner with his family, because they like to have a full table of delicious food, and usually they took them all without any leftovers. I already sense that the diabetic demons are already standing beside them.
David is 1.69 meters tall and weighs up to 84 kilograms. I estimate his body mass index BMI is around 29.4 kg/m2 which is considered obese. He told me his average glycemic index is 8-9 and he thought it was not serious. I told him to seek the advice of a doctor, as I think the alarming signal is ringing. I told him that diabetes can cause many complications. Once he finds the symptoms emerge, he may be too late. I remind him to reduce weight and keep the fasting blood sugar level below 5.6 mmol/L and sugar level after meals below 7.8 mmol/L. I strongly recommended “Obesity Code” to David in order to lose weight first. He followed the method in the book, and lost 30 pounds within half a year. His blood sugar returned to normal.
The Mission of “Obesity Code”
I think every book has a mission. The mission of “Obesity Code” is to reveal the obesity problem spreading around the world. The biggest inspiration to me from this book is that I finally understand why so many people fail to lose weight. It turns out that many people use the wrong method with traditional concepts. Before reviewing this book, I will explain the definition of obesity here. If your body mass index (BMI) is over 25 kg/m2, you are obese. How to calculate the BMI? The calculation method is the weight calculated in kilograms divided by the square of the height in meters.
Assumes a person’s weight is 80 kg and his height is 1.6 meters. The BMI is 80 kg/1.62
the answer is 31.25 kg/m2 which is obesity. The author of this book is a doctor. Why does he study obesity? Because he is a nephrologist, he has seen that more and more patients with diabetic nephropathy need kidney dialysis. At present, most diabetics are type 2. Obese is the main cause of type 2 diabetes. If we do not solve the problem, he thought, there will be more and more type 2 diabetic patients, and eventually more and more patients will have diabetic nephropathy. Even though we train up more nephrologists cannot solve the problem. The author is determined to study the solution to obesity in depth. In the beginning, he had difficulties.
The author said when he was in medical school, he never learned how to help people lose weight. Although he has become a nephrologist, his knowledge of nutrition is very little and poor. In the end, he decided to ask the most basic question of why a person becomes obese.
Is Obesity Due to Eating Too Much and Moving Too Little?
The traditional concept tells us that there are two major causes of obesity. The first is “Eating too much”. The second is “Moving too little”. If you want to lose weight, the easiest and most direct way is to eat less and exercise more. Another conventional wisdom about obesity
is that losing weight requires willpower. If you fail to lose weight purely because your will has insufficient strength. Do you think the above concept is correct? Let us read further.
In 2010, an online survey in the United States found 61% of respondents believed obesity was caused by choices of diet and exercise that personal willpower. It is all because they refuse to eat less and exercise. In the same study, 49% of people think insurance companies should charge more premiums to obese people, which indirectly reflects that many people think obese people should pay for their lack of willpower to reduce weight. But the author believes obesity has nothing to do with a person’s willpower. He used a very interesting metaphor to explain that if a person can successfully complete medical school, he needs to go through countless nights in the hospital, and finally obtain a specialist qualification through hard work. Then he becomes a specialist doctor. Would you say he lacks willpower? If there is no problem with the willpower of a doctor, why would there be obese doctors in the world?
Even today, many people still think that obesity is due to a person’s lack of willpower. “Eat too much, exercise too little” and as a result they become fatter and fatter. This book tells us that this concept is completely wrong. You believe that there are a few friends around you who will not get fat no matter how much they eat. And there will always be friends who will tell you that they get fat just by drinking water. Even breathing will make you fat!
Is Obesity Determined By Congenital Factors or Acquired Factors?
Here we will first discuss a question. Obesity is mostly determined by congenital factors? Or is it determined by acquired factors? A study was conducted in Denmark in 1986. The researchers found 540 children who were adopted from childhood. The time the study was conducted, they had grown up and the average age was 42. The researchers then used official government records to track down their biological parents and adoptive parents. The concept of this study is very simple. These children are congenital because they are inherited from their biological parents. But they have lived with their adoptive parents. So their acquired living habits will be similar to their adopted parents. If their body mass index is close to their biological parents when they grow up, then obesity is mostly determined by congenital factors.
On the contrary, if their body mass index is close to that of their adoptive parents when they grow up, then it is mostly determined by acquired factors. The studies have found that when adopted children grow up their body mass index is very close to that of their biological parents.and there is no relationship between the body mass index of their adoptive parents.
Can Calories In And Calories Out Work For Obesity?
There are more and more medical studies showing that if the mothers gained a lot of weight during pregnancy, the new born babies will also weigh more when they are born. The chance of becoming obese in the future will also be higher. If 70% of obesity is congenitally determined, what is the 30% acquired factor? One school of people thinks it is related to calorie intake, and thus derives a set of concepts called calories in calories out. What is a calorie? A calorie is a kind of energy unit of one calorie is defined as raising one litre of water by one degree Celsius. Traditionally, people think obesity is due to excess intake of calories. That is, the more a person eats, the more calories he consumes. If he does not exercise and burns the excess calories the body will accumulate more calories, so the body will become fat. Therefore, the traditional view is that
Calories in – Calories out = Body fat
Actually calories from fat are highest on an equal weight of food.
As long as you eat less high-fat food, you will reduce the calories entering the body. If you increase exercise, the body will produce more calories, so that we can lose weight.
But the author thinks this concept is wrong. He cites five points to refute this theory

Actually, for type 2 diabetics with obesity, it is better to keep track of what you eat that spikes the blood sugar. The best device for diabetics related to food is Abbott FreeStyle Libre 2
