A Publishers Weekly Best Book of the Year From an obesity and neuroscience researcher with a knack for engaging, humorous storytelling, The Hungry Brain uses cutting-edge science to answer the questions: why do we overeat, and what can we do about it? No one wants to overeat. And certainly no one wants to overeat for years, become overweight, and end up with a high risk of diabetes or heart disease--yet two thirds of Americans do precisely that. Even though we know better, we often eat too much. Why does our behavior betray our own intentions to be lean and healthy? The problem, argues obesity and neuroscience researcher Stephan J. Guyenet, is not necessarily a lack of willpower or an incorrect understanding of what to eat. Rather, our appetites and food choices are led astray by ancient, instinctive brain circuits that play by the rules of a survival game that no longer exists. And these circuits don’t care about how you look in a bathing suit next summer. To make the case, The Hungry Brain takes readers on an eye-opening journey through cutting-edge neuroscience that has never before been available to a general audience. The Hungry Brain delivers profound insights into why the brain undermines our weight goals and transforms these insights into practical guidelines for eating well and staying slim. Along the way, it explores how the human brain works, revealing how this mysterious organ makes us who we are.

“One of the most profound and illuminating studies of this century to have been published in recent decades.”—John Gray, New York Times Book Review Hailed as “a magisterial critique of top-down social planning” by the New York Times, this essential work analyzes disasters from Russia to Tanzania to uncover why states so often fail—sometimes catastrophically—in grand efforts to engineer their society or their environment, and uncovers the conditions common to all such planning disasters. “Beautifully written, this book calls into sharp relief the nature of the world we now inhabit.”—New Yorker “A tour de force.”— Charles Tilly, Columbia University

This book is guaranteed to spark lively debates and critical thinking in any classroom! Two of the most respected voices in education identify 50 myths and lies that threaten America's public schools. Berliner and Glass argue that many citizens conception of K12 public education in the United States is more myth than reality. Warped opinions about our nations public schools include: they are inferior to private schools; they are among the worst in the world in math and science; teachers should be fired if their students dont score at the national average, and on and on. With more than a little humor, Berliner and Glass separate fact from fiction in this comprehensive look at modern education reform. They explain how the mythical failure of public education has been created and perpetuated in large part by political and economic interests who stand to gain from its destruction. They expose a rapidly expanding variety of organizations and media that intentionally misrepresent facts. Where appropriate, they name the promoters of the hoax and point out how their interests are served by encouraging false beliefs. Their method of debunking these falsehoods is to argue against their logic, criticize the data supporting them, and present more credible contradictory data. This dynamic book features short essays on important topics to provide every teacher, administrator, school board member, and concerned parent with reliable knowledge from authoritative sources.
