"What if we are being programmed from birth to be fatter than we should be? That question is at the heart of new research into endocrine-disrupting chemicals, chemicals that may be contributing to the obesity epidemic. Over the past three decades, the developed world has become increasingly overweight, even after years of struggling to eat less and exercise more. Some scientists began to wonder whether there was another reason besides calories in and calories out, particularly when they noticed that lab animals used in experiments with chemicals were putting on weight. [The program] explores controversial new science that suggests exposure to man-made chemicals, starting in the womb, may be triggering changes to our metabolism that result in life-long weight gain."--Container.

"Man-made chemicals may be programming us to be fat -- before we're even born." Originally broadcast on the CBC series The Nature of things on January 12, 2012.
