Why you’ve never been able to lose weight, and how that can change now
Everything you believe about how to lose weight is wrong. Weight gain and obesity are driven by hormones—in everyone—and only by understanding the effects of insulin and insulin resistance can we achieve lasting weight loss.
In this highly readable and provocative book, Dr. Jason Fung sets out an original, robust theory of obesity that provides startling insights into proper nutrition. 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.
“Fung zeroes in on why insulin resistance has become so prevalent and offers specific outside-the-box solutions that have emerged as the key to maximizing health."

In 2014, James Hamblin launched a series of videos for The Atlantic called "If Our Bodies Could Talk." With it, the doctor-turned-journalist established himself as a seriously entertaining authority in the field of health. Now, in illuminating and genuinely funny prose, Hamblin explores the human stories behind health questions that never seem to go away—and which tend to be mischaracterized and oversimplified by marketing and news media. He covers topics such as sleep, aging, diet, and much more:
• Can I “boost” my immune system?
• Does caffeine make me live longer?
• Do we still not know if cell phones cause cancer?
• How much sleep do I actually need?
• Is there any harm in taking a multivitamin?
• Is life long enough?
In considering these questions, Hamblin draws from his own medical training as well from hundreds of interviews with distinguished scientists and medical practitioners. He translates the (traditionally boring) textbook of human anatomy and physiology into accessible, engaging, socially contextualized, up-to-the-moment answers. They offer clarity, examine the limits of our certainty, and ultimately help readers worry less about things that don’t really matter.
If Our Bodies Could Talk is a comprehensive, illustrated guide that entertains and educates in equal doses.
