In his book, *The Obesity Code*, Dr. Jason Fung argues that obesity is caused by hormones, specifically the overproduction of insulin, rather than a lack of self-control. He recommends intermittent fasting as a solution. Fung's book has been packaged with other books that promote a ketogenic diet, and Fung himself recommends full-fat dairy products. However, it is unclear whether he addresses how his recommendations compare to a ketogenic diet.

What You'll Learn
Intermittent fasting
Dr. Fung's signature prescription for patients with obesity and type 2 diabetes is his intermittent fasting protocol. He emphasizes that the stress hormone cortisol causes weight gain and that lowering insulin levels is crucial in addressing obesity. However, some readers of the book wish that Dr. Fung had addressed concerns about whether fasting triggers an increase in cortisol levels.
In *The Obesity Code*, Dr. Fung provides a comprehensive guide to intermittent fasting, including dos and don'ts, and highlights the importance of sleep and meditation for health and weight loss. He also emphasizes the importance of choosing nutritious, organic whole foods and avoiding processed foods with hidden sugars.
The combination of intermittent fasting and a ketogenic diet is considered a winning approach by some, as they believe it helps achieve weight loss and improves overall health. The ketogenic diet is particularly effective at lowering insulin levels and reducing appetite. However, it is important to note that there is limited data on the long-term effectiveness of dietary protocols, and individual preferences and health conditions should be considered when choosing a diet plan.

Insulin resistance
To prevent insulin resistance, it is crucial to maintain a healthy weight and stay physically active. Eating a balanced diet with non-starchy vegetables, fruits, whole grains, and lean proteins can help reduce blood sugar and decrease insulin levels. Other lifestyle changes, such as managing stress and getting enough sleep, are also beneficial.
In his book, "The Obesity Code," Dr. Jason Fung argues that obesity is caused by hormonal imbalances, particularly the overproduction of insulin, which leads to insulin resistance. He emphasizes the importance of intermittent fasting and dietary changes to reverse insulin resistance and promote weight loss.
The ketogenic diet, which involves combining intermittent fasting with a low-carbohydrate, high-fat diet, has been praised for its effectiveness in lowering insulin levels and reducing appetite. While Dr. Fung does not directly compare the ketogenic diet to his intermittent fasting protocol in "The Obesity Code," his focus on insulin resistance and hormonal balance aligns with the principles of the ketogenic approach.

Weight loss
In his book, 'The Obesity Code', Dr. Jason Fung posits that obesity is caused by hormones, specifically the overproduction of insulin, rather than a lack of self-control. He recommends intermittent fasting as a solution to obesity. Fung's theory is that insulin resistance is the driving force behind most "diseases of civilization", including heart disease, cancer, and Alzheimer's disease. Thus, even individuals with a normal weight can benefit from addressing insulin resistance.
The ketogenic diet is a low-carbohydrate, high-fat, moderate-protein diet that induces the production of ketone bodies by mimicking the breakdown of a fasting state. It has been shown to be one of the most effective strategies for weight loss in recent years, with many studies demonstrating its physiological and biochemical basis for inducing effective weight loss. The ketogenic diet is also very effective at lowering insulin levels, which is a key hormone that drives weight gain.
The ketogenic diet and intermittent fasting are often discussed in conjunction with each other, as they are believed to complement each other. Intermittent fasting involves alternating periods of eating and fasting, which can help regulate insulin levels and promote weight loss. In Dr. Fung's book, he provides a simple roadmap for fasting, outlining the basic dos and don'ts.
While the ketogenic diet has been shown to be effective for weight loss, it is important to note that there is no one-size-fits-all solution for weight loss. Individual results may vary, and it is always recommended to consult with a healthcare professional before starting any new diet or fasting protocol. Additionally, addressing lifestyle factors, such as dietary habits and physical activity, is crucial for long-term weight loss and weight maintenance.
In summary, the ketogenic diet and the principles outlined in 'The Obesity Code' share similarities in their focus on lowering insulin levels and addressing hormonal imbalances associated with weight gain. Both approaches have been found to be effective for weight loss, and combining them through intermittent fasting can be a powerful strategy for achieving weight loss goals and improving overall health.

Ketogenic diet benefits
The ketogenic diet has been around since the 1920s, when it was used to treat children with epilepsy. Today, it is a popular weight-loss tool. The diet involves eating high-fat foods and severely limiting carbohydrates to burn fat. When your body burns fat instead of glucose for energy, it enters a metabolic state called ketosis.
There are several benefits to the ketogenic diet. Firstly, it is a very effective way to lose weight. Studies show that people on low-carb diets lose weight faster than those on low-fat diets, even when the latter are actively restricting calories. This is because low-carb diets rid excess water from your body, lowering insulin levels and leading to rapid weight loss.
Secondly, the ketogenic diet can help to reduce appetite. When people cut carbs and eat more protein and fat, they tend to eat fewer calories. This makes it easier to stick to the diet and lose weight.
Thirdly, the ketogenic diet can be beneficial for people with diabetes and insulin resistance. Cutting carbs lowers both blood sugar and insulin levels. In one study, 95% of people with type 2 diabetes had reduced or eliminated their glucose-lowering medication within six months of starting a low-carb diet.
Finally, the ketogenic diet may have benefits beyond weight loss and blood sugar control. It has been shown to improve cholesterol and blood pressure and may even help prevent chronic and degenerative diseases such as Alzheimer's and Parkinson's.

Obesity causes
In his book, *The Obesity Code*, Dr Jason Fung posits that obesity is caused by hormones, specifically the overproduction of insulin, rather than a lack of self-control. He argues that obesity is not about calories, fat grams, or exercise. When insulin levels are too high for too long, we develop "insulin resistance", which can lead to weight gain. This is supported by a review of the book, which states that a ketogenic diet is effective at lowering insulin levels and reducing appetite.
Obesity is a complex issue influenced by multiple factors, including individual behaviours, environmental factors, and genetics. Here are some of the key causes of obesity:
Energy Imbalance: Obesity can develop when there is an energy imbalance in the body, where the energy consumed (calories) exceeds the energy used. This is often associated with consuming large amounts of processed or fast food, which tend to be high in fat and sugar. Excess calories that are not used through physical activity are stored as fat in the body, leading to weight gain.
Genetics: Genes play a significant role in obesity. Certain genetic traits, such as having a large appetite, can make weight management more challenging. Additionally, rare genetic conditions like Prader-Willi syndrome and polycystic ovary syndrome (PCOS) are associated with weight gain.
Lifestyle and Environmental Factors: Unhealthy lifestyle choices, such as a lack of physical activity, can contribute to obesity. High amounts of sedentary behaviour, including screen time, have been linked to a higher body mass index (BMI). Environmental factors, such as easy access to unhealthy food options and the influence of social and cultural norms, can also impact an individual's risk of obesity.
Medical Conditions and Medications: Certain medical conditions, such as hypothyroidism and Cushing's syndrome, can lead to weight gain. Additionally, some medications can cause weight gain by disrupting the chemical signals that regulate hunger in the brain.
While Dr Fung's book focuses on the hormonal aspect of obesity, it is important to acknowledge that obesity is a multifaceted condition influenced by a combination of genetic, behavioural, environmental, and physiological factors.

Frequently asked questions
The Obesity Code focuses on obesity as a hormonal disorder, with the main culprit being insulin resistance. It argues that obesity is not about calories, fat grams, or exercise. On the other hand, the Ketogenic Diet is primarily a low-carbohydrate, high-fat, moderate-protein diet that induces the production of ketone bodies and reduces insulin levels.
Both approaches acknowledge the importance of lowering insulin levels and reducing appetite to achieve weight loss. Intermittent fasting is a key component of both methods, and they both emphasise the importance of nutritional choices and lifestyle changes.
Both methods have been shown to be effective for weight loss. The Ketogenic Diet has been widely studied and is considered a successful approach for weight loss and improving cardiovascular risk parameters. The Obesity Code's focus on hormones and insulin resistance provides a scientific strategy for weight loss, and it also acknowledges the importance of nutritional choices and lifestyle changes. The best approach depends on individual preferences and specific health goals.
