Why do some people grow fat and others remain thin on an almost identical diet? This is still something of a mystery, in spite of many attempts to find out the causes of obesity. What is certain, however, is that obesity can be controlled and corrected. This programme records some of the experiments that have been carried out, explodes some popular fallacies, and gives an outline of the facts about diet, weight, and exercise.
