In this book, Herman Pontzer challenges conventional wisdom about metabolism, exercise, and weight loss. His groundbreaking research shows that exercise does not increase our metabolism; instead, humans burn calories within a narrow range of nearly 3,000 calories per day, regardless of activity level. This evolutionary strategy, while beneficial for survival in times of famine, contributes to modern obesity. Pontzer emphasizes that weight loss requires cutting calories and that all diets succeed or fail based on calorie intake. He also stresses the importance of exercise for maintaining optimal body function, even if it does not lead to weight loss. The book is filled with facts, memorable anecdotes, and insights into how metabolism controls various aspects of health, from fertility to immune function.
Each Sunday, TED shares an episode of another podcast we think you'll love, handpicked for you… by us. From metabolism gummies to spicy foods, the Keto diet to intricate exercise routines — it seems there’s always something that is being sold or promoted to speed up your metabolism. But do most of us even know what our metabolism IS? And is there any way to hack it (you know, so we can eat pizza all day and not stress about it)? In this episode of Body Stuff with Dr. Jen Gunter, Dr. Jen outlines what science knows about this process and why the myths and misunderstandings about our metabolism’s ability to change can actually do us more harm than good.
