The daily metabolic rate of the post-obese and the lean.
Daily metabolic rates of 16 post-obese women and 16 matched, lean controls were measured at three different levels of activity in a room respirometer. Both groups had similar height, weight, age, and other anthropometric indices. Results show that the post-obese have metabolic rates approximately 15% lower than their controls at any level of activity. They also eat less. Slimmed-down, obese women have a normal body composition. For both groups, aerobic exercise did not have a prolonged stimulatory effect on metabolic rate after the exercise had finished. Mild exercise was more effective than aerobic exercise in increasing daily metabolic rate because it could be comfortably sustained for a longer time. Implications of these findings are discussed in relation to the etiology and treatment of obesity.
