The best exercise routine, according to your muscle clocks with Professor Karyn Esser
Our bodies naturally follow a roughly 24-hour cycle, called our circadian rhythm. And every cell has a rhythm.
As we get older, we tend to lose muscle, making us more prone to falls and less able to live independently. Though we can't stop aging, staying active helps keep our muscles strong and our bodies healthy for longer.
Prof. Karyn Esser is a specialist in how the body's natural rhythms affect muscles. Today, she guides us through the latest research and shows that it's always possible to harness the power of your muscles to enhance your quality of life. She is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center.
In today's episode of ZOE Science & Nutrition, Jonathan and Karyn explore the body's internal clocks and ask: why do our muscles have their own schedule, and is there an ideal time of day to exercise?

The surprising truth about histamine intolerance
We've probably all heard of “antihistamines,” medications that can ease symptoms of hay fever and other allergies.
But what is “histamine”? It’s a vital chemical that our bodies produce, and it plays a role in a number of functions that support our health.
Histamine intolerance seems to be increasingly common, but it’s difficult to diagnose. Some people may not be aware that they have it or how to treat it.
In today’s episode of ZOE Science & Nutrition, Jonathan speaks with Dr. Will Bulsiewicz, ZOE’s U.S. medical director, to learn more about this flourishing area of research — and the best ways to identify and treat histamine intolerance.
Will is a board-certified gastroenterologist, and New York Times bestselling author of the microbiome book Fiber Fueled.

Mushrooms as medicine: Uncovering the health secrets of fungi
They’re not a plant or an animal — fungi are their very own kingdom of life. And their unique composition means they offer novel, often unbelievable, benefits to our health. Certain species of fungi are currently used to treat conditions ranging from cancer to depression.
The love of mushrooms (or mycophilia) has grown in recent years. And at the heart of this movement is biologist Dr. Merlin Sheldrake, author of the bestseller Entangled Life: How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures.
In today’s episode of ZOE Science & Nutrition, Jonathan, Merlin, and ZOE Co-Founder Prof. Tim Spector ask: Why are mushrooms so special?

The truth about the Mediterranean diet
Each day this week, we examine one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll discover these diets' true impact on your health.
Today, we’re talking about the Mediterranean diet. This indulgent diet champions vegetables, beans, fish, and even red wine, all with a liberal helping of extra virgin olive oil.
However, this relatively high-fat diet undergoes many regional adaptations, and the wide range of options can be confusing, even intimidating, if you’re not that confident in the kitchen.
In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, Professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center. Together, they discuss this diet's potential health benefits and pitfalls.

Does calorie counting improve your health?
Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out these diets' true impact on your health.
Today, we’re talking about the century-old paradigm of weight management — calorie counting. Rooted in the law of thermodynamics, the notion is simple: Consuming fewer calories than expended results in weight loss.
While seemingly straightforward, the practical application of calorie counting can prove challenging, with many of us underestimating our calorie intake or finding it difficult to maintain this diet long-term.
In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, Professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center. Together, they explore this diet's complexities, addressing its potential and pitfalls.

The carnivore diet exposed: Healthful or harmful?
Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out the true impact of these diets on your health.
Today, we’re talking about the carnivore diet, a zero-carb approach centered on meat, fish, eggs, and minimal dairy while excluding all plant foods and alcohol.
Advocates claim it can help with autoimmune conditions, type 2 diabetes, and weight loss, asserting that our ancestors thrived eating this way. However, there are questions about nutrient deficiencies and excessive saturated fat intake with this diet.
In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, Professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center. Together, they explore its purported advantages and drawbacks.

Does the paleo diet hold the secret to health?
Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out the true impact of these diets on your health.
Today, we’re talking about the paleo diet, rooted in the idea of emulating our hunter-gatherer ancestors after concerns about the impact of a modern westernized diet packed with highly processed foods.
However, the diet often involves consuming increased amounts of saturated fats, primarily from meat. This is associated with heightened cholesterol levels and heart disease risk.
In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, Professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center. Together, they dissect the diet’s potential benefits, pitfalls, and sustainability.

Are low-fat diets bad for your health?
Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out these diets' true impact on your health.
Today we’re talking about the low-fat diet, popularised in the 1970s and fueled by the belief that fat was the culprit behind heart disease and weight gain.
However, the aftermath saw a surge in low-quality carbs. Food manufacturers, in the quest for low-fat options, replaced fats with sugar and refined grains, resulting in us opting for low-quality carbs over whole foods and whole grains.
In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, a professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center. Together, they unravel the complexities of the low-fat diet, addressing its potential and pitfalls.

Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out these diets' true impact on your health.
Today we’re talking about the keto diet, a global phenomenon favoring fats over carbs, lauded for potential health benefits like improved blood sugar control and weight loss.
Yet, the allure of keto does come with downsides. With a dearth of fiber and essential nutrients — as well a reputation for being notoriously difficult to keep on top of long-term — many find ketosis elusive.
In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, a professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center.

Exercise myths busted: Practical steps to sustain your health
Admit it, exercise isn't everyone's favorite pastime. Of course, our ancestors weren't hitting the gym by choice — our evolution has wired us to stay active, and this natural activity actually slows down the aging process.
The good news is that you can achieve the benefits without feeling like you're "exercising."
In today’s episode, Prof. Daniel Lieberman debunks exercise myths. He also teaches us how exercise impacts our health and how learning from our evolution can unlock the secrets of a longer life.
Daniel Lieberman is a paleoanthropologist at Harvard University. He’s the Edwin M. Lerner II Professor of Biological Sciences and a professor in the Department of Human Evolutionary Biology. He’s best known for his research on the evolution of the human mind and the human body.

Gut microbiome testing: What can it reveal about your health?
Your gut microbiome, a bustling community of microorganisms, is a vital player in your overall health. It doesn’t just impact your digestive system — it has a profound influence on your brain health and well-being.
However, the gut microbiome is a complex, long misunderstood realm, and figuring out how it affects daily life can leave even the most dedicated health enthusiasts scratching their heads.
Here at ZOE, we’ve transformed our understanding of this bustling microbial world, where both “good” and “bad” gut bacteria reside.
In today’s episode, Jonathan speaks with Prof. Nicola Segata and Prof. Tim Spector to explore how ZOE's microbiome testing and unique microbiome health scores provide personalized insights into your gut health.

The shocking damage ultra-processed foods cause to your brain
There’s been a surge in our consumption of ultra-processed foods, especially in the United Kingdom and the United States, where these foods contribute about two-thirds of people’s caloric intake.
Also a cause for concern is emerging evidence of ultra-processed foods’ detrimental effect on our brain health and overall well-being.
When most of our calories come from ultra-processed foods, the risk of chronic physical and mental health conditions escalates. Scientists are now uncovering the intricate mechanisms behind this relationship, particularly concerning the effects of these foods on our brains.
In today’s episode, we welcome back Prof. Felice Jacka, OAM. Felice is an Alfred Deakin professor of nutritional psychiatry and the director of the Food & Mood Centre at Deakin University, in Australia. She’s also the founder of the International Society for Nutritional Psychiatry Research and the world’s leading researcher on food’s impact on our brain and mental health.
Now, she’s back on the show to delve deeper into the effects of ultra-processed foods on mental health and the brain, specifically the hippocampus, an area responsible for learning and memory.

Healthy aging: The surprising power of your social life
Unfortunately, many of us spend our later years in poor health. But is this avoidable? And can we actually increase our healthy years?
While aging is inevitable, there are steps we can take to minimize its effects on our health. And surprisingly, some of these steps have nothing to do with exercise or diet. Simply spending time with others can provide countless benefits to us as we age.
But how can we maintain these connections? Does retirement affect our social interactions? And can attitude alone keep you healthier in your later years?
In today’s episode, one of the world’s top experts on aging, Prof. Rose Anne Kenny, joins us to explore these ideas.
Rose Anne is a world-leading geriatrician at Trinity College Dublin, where she leads a huge, long-term study on aging. She’s also the author of the number one international bestseller Age Proof: The New Science of Living a Longer and Healthier Life.

Is dairy good or bad for you?
Decades ago, there were reams of adverts instructing us to drink our milk so we don’t break our bones. But in the decades since, public opinion toward dairy is very different, and the scientific community has largely debunked these ideas.
Many of the health-conscious among us choose to avoid it altogether. Our reasons range from a belief that dairy leads to inflammation, to acne, or even to an increased risk of heart attack due to high levels of saturated fat.
But have we fallen into the same trap we often do, bouncing from one extreme to another? Could cutting out dairy mean we miss out on vital nutrients? Or could it hold the secret to a healthy gut microbiome?
Today, Jonathan is joined by ZOE regulars and renowned experts, Dr. Sarah Berry and Prof. Tim Spector.
In this episode, you’ll not only find out whether you should eat dairy or cut it out, but you’ll also hear two leading nutritional scientists try to reach an agreement on how to translate the latest research into actionable advice. And hopefully, they’ll still remain friends afterward.
