'Ground-breaking, fascinating, important . . . we were astounded' Deliciously Ella, Delicious Ways to Feel Better A myth-busting tour of the body's hidden foundations from a pioneering evolutionary biologist Over the past twenty 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. By taking a closer look at what happens to the energy we consume, Pontzer explores the ways in which metabolism controls every aspect of our health - from fertility to immune function - and reveals the truth about the dynamic system that sustains us. Filled with facts and memorable anecdotes, Burn will change the way you think about food, exercise and life.

The Misunderstood Science of Metabolism

Burn

Herman Pontzer PhD

One of the foremost researchers in human metabolism reveals surprising new science behind food and exercise. We burn 2,000 calories a day. And if we exercise and cut carbs, we'll lose more weight. Right? Wrong. In this paradigm-shifting book, Herman Pontzer reveals for the first time how human metabolism really works so that we can finally manage our weight and improve our health. Pontzer's groundbreaking studies with hunter-gatherer tribes show how exercise doesn't increase our metabolism. Instead, we burn calories within a very narrow range: nearly 3,000 calories per day, no matter our activity level. This was a brilliant evolutionary strategy to survive in times of famine. Now it seems to doom us to obesity. The good news is we can lose weight, but we need to cut calories. Refuting such weight-loss hype as paleo, keto, anti-gluten, anti-grain, and even vegan, Pontzer discusses how all diets succeed or fail: For shedding pounds, a calorie is a calorie. At the same time, we must exercise to keep our body systems and signals functioning optimally, even if it won't make us thinner. Hunter-gatherers like the Hadza move about five hours a day and remain remarkably healthy into old age. But elite athletes can push the body too far, burning calories faster than their bodies can take them in. It may be that the most spectacular athletic feats are the result not just of great training, but of an astonishingly efficient digestive system. Revealing, irreverent, and always entertaining, Pontzer has written a book that will change how you eat, move, and live.

New Research Blows the Lid Off How We Really Burn Calories, Lose Weight, and Stay Healthy

Picked this up after hearing him on a podcast - interesting but quite depressing book the looks at food / eating / exercise & diet it’s impact on ourselves & the planet. 
Chapter on energy constraint interesting - from his research 
“Humans and other species adapt dynamically to changes in daily physical activity, maintaining total energy expenditure within a narrow range. Chronic exercise thus suppresses other physiological activity, including immunity, reproduction, and stress response. This exercise-induced downregulation improves health at moderate levels of physical activity but can be detrimental at extreme workloads.”
