In addition to his five basic steps, a set of lifelong habits that will improve your health and control your insulin levels, Dr. Fung explains how to use intermittent fasting to break the cycle of insulin resistance and reach a healthy weight—for good.

• why fasting is actually good for health
• who can benefit from fasting (and who won't)
• the history of fasting
• the various ways to fast: intermittent, alternate-day, and extended fasting
• what to expect when starting to fast

The must-have guide to reversing and preventing type 2 diabetes through intermittent fasting and a low-carb, high-fat diet—from Dr. Jason Fung, internationally best selling author of The Obesity Code.

Today, most doctors, dietitians, and even diabetes specialists consider type 2 diabetes to be a chronic and progressive disease—a life sentence with no possibility of parole. But the truth, as Dr. Fung reveals in this paradigm-shifting book, is that type 2 diabetes is reversible. Writing with clear, persuasive language, he explains why conventional treatments that rely on insulin or other blood-glucose-lowering drugs can actually exacerbate the problem, leading to significant weight gain and even heart disease. The only way to treat type 2 diabetes effectively, he argues, is proper dieting and intermittent fasting—not medication.

Author of the international bestsellers The Diabetes Code and The Obesity Code Dr. Jason Fung returns with an eye-opening biography of cancer in which he offers a radical new paradigm for understanding cancer—and issues a call to action for reducing risk moving forward.

Our understanding of cancer is slowly undergoing a revolution, allowing for the development of more effective treatments. For the first time ever, the death rate from cancer is showing a steady decline . . . but the “War on Cancer” has hardly been won.

In The Cancer Code, Dr. Jason Fung offers a revolutionary new understanding of this invasive, often fatal disease—what it is, how it manifests, and why it is so challenging to treat. In this rousing narrative, Dr. Fung identifies the medical community’s many missteps in cancer research—in particular, its focus on genetics, or what he terms the “seed” of cancer, at the expense of examining the “soil,” or the conditions under which cancer flourishes. Dr. Fung—whose groundbreaking work in the treatment of obesity and diabetes has won him international acclaim—suggests that the primary disease pathway of cancer is caused by the dysregulation of insulin. In fact, obesity and type 2 diabetes significantly increase an individual’s risk of cancer.

In this accessible read, Dr. Fung provides a new paradigm for dealing with cancer, with recommendations for what we can do to create a hostile soil for this dangerous seed. One such strategy is intermittent fasting, which reduces blood glucose, lowering insulin levels. Another, eliminating intake of insulin-stimulating foods, such as sugar and refined carbohydrates.

For hundreds of years, cancer has been portrayed as a foreign invader we’ve been powerless to stop. By reshaping our view of cancer as an internal uprising of our own healthy cells, we can begin to take back control. The seed of cancer may exist in all of us, but the power to change the soil is in our hands.

Take the guesswork (and fear) out of fasting with real-life and expert advice

In recent years, intermittent fasting—restricting calorie intake for a set number of hours or days—has become an increasingly popular diet strategy. While some in the medical community initially dismissed the idea as a dangerous fad, recent research not only validates the safety of fasting for weight loss but also offers compelling evidence of wide-ranging health benefits, from reversal of diabetes and other metabolic disorders to enhanced cognitive function and increased longevity.

But for many who are eager to try out fasting, the regimen can feel a bit intimidating. After all, abstaining from food doesn’t sound like much fun. People rightly wonder: How often can I eat? Will I be able to focus at work? Will I have enough energy to exercise? And perhaps the most concerning question of all: Won’t I be hungry all the time?!

Enter Dr. Jason Fung—world-renowned fasting expert—his colleague, Megan Ramos, and Eve Mayer, who has experienced the life-changing benefits of fasting through Dr. Fung’s program. Together, they’ve teamed up to write a one-of-a-kind guide that answers the most common questions people have about fasting—and offers a customizable program that provides real results.

In Life in the Fasting Lane, Dr. Fung, Ramos, and Mayer take the reader by the hand and walk them through the basics of a fasting lifestyle—from the science behind fasting as a health and weight loss strategy to the real-life choices and dilemmas people commonly encounter. While Dr. Fung and Ramos explain the fundamentals of fasting and offer a customizable approach, Mayer shares her in-the-trenches perspective and hard-won knowledge as a success story who turned her life around with fasting.

With chapters that address everything from meal planning to mental strategies; exercise to socializing, Life in the Fasting Lane is a unique and accessible guide to developing a sustainable and beneficial fasting routine that offers dramatic, lifelong results.
