Your Summer Reading List, The Energy Edition

Books that support your cellular energy


It’s beach season — which means it’s also the season of stacking up books you’ve been meaning to read, packing them in your bag next to the sunscreen, and (let’s be honest) reading maybe three of them. This summer, Countdown wants to make those three count.

We’ve pulled together 13 books that are perfect poolside, on a porch, or tucked into a beach bag — but that also happen to be some of the smartest reads out there on energy, vitality, and what’s really going on inside your cells. Think of it as a reading list that works double duty: equal parts beach read and brain food, equal parts nature writing and science.

Because here’s the thing: whether a book is about mitochondria specifically, or about hormones, sleep, stress, or the science of aging well, it all comes back to the same idea. Your cells are where your energy is made. And understanding how to support them is really just another way of understanding how to feel better, think more clearly, and live with more vitality, in every facet of life.

So consider this your syllabus for a smarter summer. Grab a copy (or thirteen), and get ready — your cells are going to love this summer’s reading list and because these are affiliate links below, when you purchase them we’ll invest the earnings back into mitochondrial research.

Optimize

By Dr. Catherin Clinton

A fascinating look at how light, water, sound, and the world around you shape your health at the cellular level by quantum biology expert and naturopathic physician Dr. Catherine Clinton.

We are biologically wired to exchange energy with our environment—yet modern life has severed this essential connection. Sunlight directs hormone signaling and immune function.

From the #1 bestselling author of The New Menopause comes a fresh, brand-new guide to the transition that often starts years before anyone tells you it’s happening. Dr. Mary Claire Haver—the trailblazing voice behind the movement to revolutionize health care for women—sets things straight.

Though menstrual cycle changes and the emotional rollercoaster that accompanies them are the hallmarks of the transition to menopause, many women with regular periods as young as 35 can also start to feel irregular, with symptoms that include anxiety, fatigue, joint pain, brain fog, sexual symptoms, and volatile moods. This array of symptoms can be hugely disruptive—all the more so when a doctor dismisses a woman’s complaints as all in her head or prescribes unnecessary and potentially harmful treatment. In this book, she explains that the numerous and varied symptoms of perimenopause occur in direct response to normal endocrine changes; this is the hormonal “zone of chaos.” Whether you have symptoms or not, The New Perimenopause helps remove the mystery around this time of change, putting women in control of their health going forward.

Protocols: An Operating Manual for the Human Body

by Andrew D. Huberman PhD

From Andrew Huberman, host of the world’s leading health podcast Huberman Lab, comes an essential guide to improving brain function, optimizing your physical health and performance, enhancing mood and energy, rewiring your nervous system, and more.

The power of your physiology can be harnessed in two complementary ways. First, through a set of foundational behaviors—core practices that substantially improve your day-to-day mental and physical state. Second, through targeted behaviors—specific tools you can use to overcome common challenges. In this book, Andrew Huberman brings both together in a set of essential “protocols.” Pre-order for your fall reading.

Power, Sex, Suicide

By Nick Lane, PhD

The OG mitochondria book, a modern classic of popular science that explains why these tiny organelles are basically responsible for life as we know it from the accomplished Nick Lane, the recipient of the 2027 Countdown Award which will be presented at the Evening of Energy Gala on January 30th, 2027.

In this fascinating and thought provoking book, Nick Lane brings together research findings in this exciting field to show how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don’t we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death. And let’s be honest, this title will get some attention at the beach.

Forever Strong

By Dr. Gabrielle Lyon

After years of watching patients cycle through her practice, Dr. Gabrielle Lyon noticed a pattern. While her patients struggled with a wide range of conditions, they all suffered from the same core problem: they had too little muscle rather than too much fat.

When we think about muscle, we tend to think about strength or aesthetics, but in reality, muscle accounts for so much more than that. As the body’s largest endocrine organ, muscle actually determines everything about the trajectory of health and aging. Many of the conditions Dr. Lyon’s patients were experiencing were actually symptoms of underdeveloped or unhealthy muscle.

Now, Dr. Lyon offers an easy-to-follow food, fitness, and self-care program anchored in evidence and pioneering research that teaches you how to optimize muscle—no matter your age or health background. Discover how to overcome everything from obesity to autoimmune disorders and avoid diseases like Alzheimer’s, hypertension, and diabetes by following Dr. Lyon’s powerful new approach to becoming forever strong.

Brain Energy

By Dr. Christopher Palmer

We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat?

In Brain Energy, Harvard psychiatrist, and member of Countdown’s Scientific & Medical Advisory Board, Dr. Chris Palmer unites our existing knowledge about mental illness within a single framework: Mental disorders are metabolic disorders of the brain. The root cause of mental illness isn’t merely genetics or a chemical imbalance, but rather the energy available for your brain.

Palmer explains this new understanding of mental illness in detail, from symptoms and risk factors to what is happening in brain cells, and sheds light on the new treatment pathways this theory opens up for all mental disorders, including anxiety, depression, ADHD, alcoholism, eating disorders, bipolar disorder, autism, and even schizophrenia.

The Inner Clock

By Lynne Peeples

Your body contains a symphony of tiny timepieces, synchronized to the sun and subtle signals in your environment and behavior. But modern insults like artificial light, contrived time zones, and late-night meals can wreak havoc on your internal clocks.

Armed with advances in biology and technology, a circadian renaissance is reclaiming those lost rhythms. The Inner Clock explores the emerging science and its transformative applications: How could taking a walk in the morning and going to bed at the same time each night keep your body  in sync? Why are some doctors prescribing treatments at specific times of day? And how might a better understanding of our circadian rhythms improve educational outcomes, optimize sports performance, and support the longevity of our planet?

Science journalist Lynne Peeples seeks out the scientists, astronauts, athletes, and patients at the forefront of a growing movement. Along the way, she sleeps in a Cold War-era bunker, chases the midnight sun, spits into test tubes, and wears high-tech light sensors to decipher what makes our internal clocks tick and how we can reset them for the better.

Unbreakable

By Dr. Vonda Wright

Strong skeletal muscle drives healthy longevity yet too often women in particular neglect this important measure of fitness. Indeed, more than 70% of women experience musculoskeletal symptoms like joint pain, muscle loss, and reduced bone density as they enter perimenopause and menopause. These symptoms—what Dr. Vonda Wright refers to as the “musculoskeletal syndrome of menopause”—can often set us up for osteoporosis, osteopenia, broken bones, increasingly limited mobility, and reduced independence later in life. That trend stops now. Unbreakable outlines a new and direct path to protecting ourselves against this too-common fate.

Drawing on her decades of experience as a pioneering orthopedic surgeon helping women at all fitness levels to repair their bones and regain strength, Dr. Wright gives clear action steps to shield us from the timebombs of aging.

Unbreakable includes a six-week, master exercise protocol to jumpstart skeletal and muscular strength, critical information about baseline blood and mobility tests that will help you understand your current health state, and twenty easy, anti-inflammatory recipes, Unbreakable is an invaluable guide to adding more vibrantly healthy life to your years.
