Why do most diets fail? Why does one person eat a certain meal and gain weight, while another eating the same meal loses pounds? Why, despite all the advice about what to eat, are we all still getting fatter? The answers are much more surprising - and fascinating - than we've been led to believe. The key to health and weight loss lies not in the latest fad diet, nor even in the simple mantra of 'eat less, exercise more', but in the microbes already inside us.

Over the past 20 years, Evolutionary Biologist Herman Pontzer has conducted ground-breaking studies across a range of settings, including pioneering fieldwork with Hadza hunter-gatherers in northern Tanzania. This book draws on his eye-opening research to show how, contrary to received wisdom, exercise does not increase our metabolism. Instead, we burn calories within a very narrow range: nearly 3,000 calories per day, no matter our activity level.

For decades we have been taught that fat is bad for us, carbohydrates better, and that the key to a healthy weight is eating less and exercising more. Yet despite this advice, we have seen unprecedented epidemics of obesity and diabetes. Taubes argues that the problem lies in refined carbohydrates, like white flour, easily digested starches, and sugars, and that the key to good health is the kind of calories we take in, not the number.

In industrialised nations, our sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases like diabetes. A key remedy, we are told, is exercise - voluntary physical activity for the sake of health. However, most of us struggle to stay fit, and our attitudes to exercise are plagued by misconceptions, finger-pointing and anxiety. But, as Daniel Lieberman shows in Exercised, the first book of its kind by a leading scientific expert, we never evolved to exercise.

Eat less, lose more: a mantra few of us would disagree with and one we’ve heard countless times in official health advice. And yet doctors treating diabetes and obesity are experiencing extraordinary results among patients by taking a different approach - not by counting calories, but by eating a low-carb, high-fat diet. Setting out the case for this ‘ketogenic’ approach to eating, Gary Taubes analyses the bad science behind the nutritional dogma that has brought us to a diabetes and obesity crisis. 

Hygiene prevents the spread of disease and saves countless lives. But in recent decades, rather than safeguarding us from illness, an obsession with ‘cleanliness’ seems to have been having the opposite effect. As we are now starting to realise, our overuse of soap, sanitisers and untested, misleading skin-care products is doing untold damage to our skin’s vital microbial layer, which influences everything from acne, eczema and dry skin to how we smell. 

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. 

How can a blind person learn to see with her tongue or a deaf person learn to hear with his skin? What does a baby born without a nose tell us about our sensory machinery? Might we someday control a robot with our thoughts? And what does any of this have to do with why we dream? The answers to these questions are not right in front of our eyes; they're right behind our eyes. This book is not simply about what the brain is but what it does. Covering decades of research to the present day, Livewired also presents new findings from Eagleman's own research.

Everyone knows how hard it can be to maintain a healthy diet. But what if some of the decisions we make about what to eat are beyond our control? Is it possible that food is addictive, like drugs or alcohol? And to what extent does the food industry know, or care, about these vulnerabilities? In Hooked, Pulitzer Prize-winning investigative reporter Michael Moss sets out to answer these questions and to find the true peril in our food. 

The latest book from the author of the Sunday Times number one best seller Feel Better in Five. It's more important than ever before that we get in shape, stay healthy and live well - Dr Chatterjee is back to show you how. Weight loss isn't a race. It isn't one size fits all. Drawing on 20 years of experience as a GP, Dr Rangan Chatterjee has created a conscious, long-lasting approach to weight loss that goes far beyond fad diets and helps to find the best solutions that work for you.

There is nothing more essential to our health and wellbeing than breathing: take air in, let it out, repeat 25,000 times a day. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it.

Ageing - not cancer, not heart disease - is the world’s leading cause of death and suffering. We accept as inevitable that as we get older our bodies and minds begin to deteriorate, and we are increasingly likely to be struck by dementia or disease. Ageing is so deeply ingrained in human experience that we never think to ask: is it necessary? 

In his first audiobook, The Lazarus Strategy, Norman will inspire listeners to embrace the coming years with equal measures of optimism and determination; celebrating the good news of his research - that staying active is scientifically proven to keep the body young and healthy and stave off age-related diseases. His lifestyle blueprint will show us that the positive changes we can make now are both simple and easily actionable but have the power to help us reap the rewards in later life and enjoy an independent and productive old age.

Strengthen your immunity for good. In this groundbreaking audiobook, expert immunologist Dr Jenna Macciochi unravels the new science around immunity and decodes exactly what it takes to be well in the modern day. Offering simple, clear and educated advice, debunking popular myths along the way, Immunity explores the secrets of people who never seem to get ill, why autoimmune disease is more prevalent than ever and how germs are actually good for us.

Intelligence is usually seen as the ability to think and learn, but in a rapidly changing world, there's another set of cognitive skills that might matter more: the ability to rethink and unlearn. In recent months, the pandemic has forced us all to reevaluate our assumptions about health and safety and multiple acts of police brutality have challenged most of us to reconsider our responsibility for fighting racism. Yet in our daily lives, too many of us still favor the comfort of conviction over the discomfort of doubt.
