title: Obesity: overview of pathogenesis and treatment.
abstract: This paper presents an overview of selected current concepts of the pathogenesis and treatment of obesity. It has been estimated using the 1981 Canada Fitness Survey data that 14.1% of Canadian adult men and 20.6% of women are greater than 20% above reference table weight. Recent advances in adipocyte metabolism and control have shown that hyperplastic obesity can occur at any age and that there are differences in the replicative rate of adipocyte precursor cells from the massively obese. Furthermore, a number of the complications of obesity, including hypertension, have been related to regional body fat distribution, independent of total body fat. It is suggested that some of the controversy on the relationship between body weight/weight loss and hypertension may be due to failure to account for this. There is now suggestive evidence that abnormalities in diet-induced thermogenesis and (or) brown adipose tissue may result in human obesity. The roles of the major treatment modalities (diet, behaviour therapy, and exercise) are reviewed as are the potential hazards of the weight loss process.
