Within each of us is an ancient mechanism that eliminates toxic materials, initiates fat burning, and protects cells against stress. It’s called autophagy, and when it’s turned on, the complex operation can not only slow down the aging process, but can optimize biological function as a whole, helping to stave off all manner of disease—from diabetes to dementia—and affording us the healthy lifespan we never thought possible.
So how can we activate this switch through diet? How frequently should we fast and for how long? Must we abstain from all foods or just specific macronutrients? What’s the sweet spot between intermittent fasting, protein restriction, and ketogenic eating?
Backed by a wealth of data, and with a practical program anyone can follow for lasting results, The Switch not only decodes the science of autophagy, but also teaches you how to control it and benefit from its profound impact.

James Clement has devoted the last two decades to the science of life extension. He is best known for his Supercentenarian Study, which has received international press (see: Betterhumans Supercentenarian Research Study in the News) in addition to a feature story in the New York Times by Pulitzer Prize–winning writer Amy Harmon. A champion of the transhumanist movement, he is the founder of the Betterhumans non-profit, which is the world’s first specifically transhumanist biomedical research organization. Led by a collection of high-profile researchers, the organization focuses on bringing cutting edge scientific discoveries from the lab to the clinic, so that humanity can take advantage of these breakthroughs in a safe and inexpensive manner, as quickly as possible.
