Obesity in Britain: gluttony or sloth?

Abstract
Department of Health statistics show that the prevalence of serious obesity doubled in Britain between 1980 and 1991 (fig 1) and is continuing to increase.4 In the United States, latest survey data show that obesity is much more prevalent than in Britain and is still increasing; in certain ethnic and regional subgroups 50% of women are clinically obese.5 The American experience provides no grounds for optimism regarding the developing epidemic in Britain.
