It is estimated that 1.4 billion adults—one in three across the globe—are overweight. Registered dietitian and health writer Clare Fleishman explores surprising new suspects contributing to our planet’s expanding girth, including air conditioning, drugs, pollution, and others which get little notice as lack of will power shoulders the blame. This important work examines how we live in a new century and why obesity has become a major killer from the American Midwest to the cities of Europe and across the deserts of Africa.
