What You'll Learn
Intermittent fasting
In his book, "The Obesity Code," Dr. Fung recommends intermittent fasting as a way to break the cycle of insulin resistance and achieve a healthy weight. He suggests that obesity is driven by hormones, particularly insulin, and that understanding the effects of insulin resistance is key to long-term weight loss. Intermittent fasting helps to regulate insulin levels and reduce inflammation in the body.
Fung's protocol does not specify the number of macronutrients, such as protein, fat, and carbohydrates, to consume. However, individuals following his protocol typically end up eating fewer carbohydrates and more protein and fat than is typical in a standard American diet. Calorie counting is not required, and there are no set meal plans or menus to follow when breaking a fast. This flexibility allows individuals to customize their fasting schedule to meet their needs.
The benefits of intermittent fasting, as outlined by Dr. Fung, include its non-invasiveness, low cost, and effectiveness in managing diabetes. He emphasizes that the root cause of diabetes and other metabolic disorders is the high-sugar, processed food-laden standard American diet. By reducing sugar intake and increasing natural, unprocessed foods, individuals can improve their health and reduce their risk of disease.
Dr. Fung's work has helped countless people transform their lives and improve their health. His approach to intermittent fasting provides a sustainable and accessible way to optimize health and well-being, demonstrating that dietary choices can have a significant impact on overall wellness.

Lowering insulin levels
Dr. Jason Fung, a Canadian nephrologist, has dedicated his career to making intermittent fasting accessible and safe. He is the author of several books, including "The Obesity Code", "The Diabetes Code", and "The Cancer Code". His work focuses on lowering insulin levels in the body to promote weight loss and improve overall health.
Insulin is a hormone that regulates blood sugar levels and promotes the storage of body fat. When blood sugar levels rise, the pancreas releases insulin to bring them back to normal. While insulin is essential for maintaining blood sugar balance, elevated insulin levels can lead to increased fat storage and weight gain. Obese individuals tend to have higher insulin levels, and this is strongly correlated with waist circumference and waist-to-hip ratio.
Dr. Fung's diet aims to lower insulin levels by reducing carbohydrate intake and incorporating intermittent fasting. He recommends a low-carbohydrate or ketogenic diet, which has been proven effective for rapid weight loss. This type of diet decreases insulin levels, which can help normalize blood sugar and reduce inflammation. Additionally, intermittent fasting provides periods of insulin deficiency, which can help break the cycle of insulin resistance and improve insulin sensitivity.
To lower insulin levels, Dr. Fung suggests choosing natural, unprocessed foods and minimizing the consumption of highly glycemic foods like white rice and potatoes. He also emphasizes the importance of sleep, as it affects insulin sensitivity and carbohydrate cravings. By balancing feeding and fasting periods, individuals can effectively manage their insulin levels and promote a healthier body composition.
In summary, Dr. Jason Fung's approach to lowering insulin levels involves a low-carbohydrate diet and intermittent fasting. This method aids weight loss, normalizes blood sugar, and reduces inflammation. By understanding the role of insulin and incorporating lifestyle changes, individuals can achieve better health and improve their overall well-being.

Eating natural, unprocessed foods
Dr. Jason Fung is a Canadian nephrologist and bestselling author of several books on intermittent fasting and low-carb diets for treating obesity and diabetes. His books include "The Obesity Code," "The Diabetes Code," and "The Cancer Code." Dr. Fung's diet plan focuses on lowering insulin levels in the body, which aids in weight loss and normalizing blood sugar levels.
Understanding Unprocessed Foods
Unprocessed foods are those that are in their natural, whole state and have not been significantly altered or refined. This includes fruits, vegetables, legumes, whole grains, nuts, and meat that has not been treated with preservatives, additives, or excessive processing. While there is no single definition, unprocessed foods are generally understood as being closer to their natural form and retaining their inherent nutritional value.
Benefits of Unprocessed Foods
Eating unprocessed foods has numerous potential health benefits. Firstly, unprocessed foods are nutrient-rich and can aid in weight loss by providing your body with essential vitamins, minerals, antioxidants, and fiber. A diet high in ultra-processed foods has been linked to an increased risk of obesity, heart disease, and even certain types of cancer. By contrast, unprocessed foods can help regulate your sleep-wake cycle, promote heart health, and support a healthy gut.
Incorporating Unprocessed Foods into Your Diet
When transitioning to a diet with more unprocessed foods, it is important to do so gradually to avoid potential side effects like fatigue, irritability, and digestive issues. Here are some specific tips:
- Focus on whole, nutrient-dense foods: Prioritize unprocessed foods that are rich in nutrients, such as fruits, vegetables, legumes, whole grains, nuts, lean meats, and seafood.
- Read labels carefully: When shopping, take the time to read the labels on food products. Look for ingredients that are recognizable and avoid those with long lists of additives, preservatives, or excessive amounts of sugar and salt.
- Shop the perimeter of the grocery store: Typically, the outer sections of grocery stores contain fresh produce, meats, and dairy, while the inner aisles are where most processed foods are found.
- Cook with natural plant oils: When preparing meals, use natural plant oils like olive oil or avocado oil instead of highly processed vegetable oils.
- Embrace herbs and spices: Enhance the flavor of your meals with fresh or dried herbs and spices, which add a burst of flavor without artificial additives.
- Be mindful of dairy: Opt for dairy products with minimal additives, and exercise caution with unpasteurized dairy due to the potential risk of harmful bacteria.
- Avoid extreme restrictions: It is not necessary to eliminate all processed foods from your diet. Enjoy your favorite processed treats in moderation, and remember that some processed foods, like yogurt or whole-grain bread, can be part of a healthy diet.

Occasional periods of fasting
Dr. Jason Fung is a Canadian nephrologist and the author of several bestselling books about intermittent fasting and low-carb diets for treating obesity and diabetes. His work focuses on lowering insulin levels in the body, which aids weight loss and has the added benefit of normalizing blood sugar levels and reducing inflammation.
In his book, *The Obesity Code*, Dr. Fung recommends occasional periods of fasting (intermittent fasting) alternated with periods of eating a low-carb or keto diet. Intermittent fasting is a dietary technique that involves restricting food and drink intake for a period of time and has been shown to provide health benefits and improve markers of health in the body.
Fung suggests that understanding weight loss requires understanding the hormonal roots of obesity. He explains that the hormone insulin is the key driver of obesity, and therefore, obesity is a hormonal, rather than a caloric, imbalance. Insulin is a fat-storing hormone that signals the body to store food energy as body fat. When we eat, insulin levels rise, and when we fast, insulin secretion decreases, allowing for decent breaks in insulin secretion, which is important for a healthy body.
Fung recommends balancing insulin-dominant periods (when we are eating) with insulin-deficient periods (when we are fasting). Intermittent fasting is an effective way to manage when to eat, and it can be customized to meet individual needs and preferences. For example, one approach is to fast for 24 hours from dinner one day to dinner the next, incorporating a cup of vegetable, chicken, or beef broth in place of lunch. This pattern can be adjusted to make it work for the individual.

Fasting and diabetes
Dr. Jason Fung is a Canadian nephrologist and functional medicine advocate. He is also the bestselling author of several books about intermittent fasting and low-carb diets for treating obesity and diabetes. His books include "The Obesity Code", "The Diabetes Code", and "The Cancer Code".
Fung's diet mainly focuses on lowering insulin levels in the body. This is achieved by reducing the intake of carbohydrates, which are known to raise insulin levels and cause the body to store more fat. By lowering insulin levels, blood sugar levels normalize and inflammation decreases, which is particularly beneficial for people with diabetes.
In his book "The Obesity Code", Dr. Fung recommends occasional periods of fasting (intermittent fasting) alternated with periods of eating a low-carb or keto diet. Very low-carbohydrate and high-fat diets, such as the ketogenic diet, have been proven effective for rapid weight loss. During periods of fasting, the body's fat-burning process is activated, allowing it to break into its fat stores for energy. This practice is known as intermittent fasting and has distinct physiological effects compared to calorie restriction.
Fung has also pioneered the use of therapeutic fasting regimens for weight loss and type 2 diabetes control at his Intensive Dietary Management clinic in Toronto. He has seen success in helping people with diabetes reduce or eliminate their need for insulin through intermittent fasting. However, experts stress caution as there can be risks associated with fasting, such as hypoglycemia, headaches, fatigue, nausea, and insomnia. It may also be less safe for certain groups, such as pregnant women and those on specific medications.
