Physical Activity and Human Obesity

Abstract
THIS report deals with the physical activity and attitudes toward such physical activity of obese and nonobese persons. Recent investigations suggest that reduced physical activity may be important in the pathogenesis of obesity. Mayer et al.1 have shown that the caloric surplus of obese hyperglycemic mice during the active phase of their obesity is due primarily to the fact that they are far less active than their nonobese litter mates. When the "waltzing gene" is bred into this strain of mice, moreover, the resultant increased activity is sufficient to prevent the development of their usual massive obesity. Finally, these authors . . .
