It's been called the world's first man-made epidemic, and it's killing us. In this riveting documentary, Dr. Stephan Rossner of Stockholm, an expert on obesity, leads us through startling evidence of how our society has created this toxic environment. Cheaper production, "supersized" fast foods and a $12 billion advertising industry are lethal when mixed with a car-dominated culture, urban sprawl and labour-saving technologies. Although North America is the epicentre of obesity, this disease is being exported worldwide as a by-product of western culture. Infiltrating low-income communities and developing nations, obesity is creating a potentially bankrupt health system. Featuring lively animation and hard-hitting science, The Weight of the World reveals that obesity is not an individual problem, but one that requires changes in public policies and attitudes.
