Trade Review"A feast for the mind." Nature "The most succinct diet book ever written." The Scientist "People should read this book. They should read it if they are obsessive weight-watchers or serial dieters, or just concerned about what their children eat. They should read it if they work in public health, the food industry, catering, or education." Times Higher Education "Along with offering a fascinating history, they show how an understanding of calorie needs saved lives in the global fight against hunger." -- Emily Kaiser Thelin The Wall Street Journal "Takes the science of calories and breaks it down for the rest of us." San Francisco Chronicle "This book will help dispel many of the commonly held myths we have about eating. An informative and interesting read for those who want to know the science behind calories, food and weight." Huffington Post Books "Does the seemingly impossible: it takes calories from the abstract to the concrete. Nestle and Nesheim explain the significance of the calorie not only in understandable scientific terms, but also in social terms with the explicit aim of helping their reader navigate the convoluted world of food labels and diet fads." Civil Eats "Presents an interesting series of opinions and overviews that are deserving of a wider audience." yum.fi
