In Reply: Drs Smith and Ebrahim suggest that
the conclusions in our article are not justified because there was no control
group. The purpose of our study was to compare short- and long-term changes
in weight and cardiovascular risk factors in patients who were randomized
to a diet combined with either continuous bouts of vigorous aerobic exercise
or accumulated lifestyle activity. The National Heart, Lung, and Blood Institute
has recently advised that "physical activity is recommended as part of a comprehensive
weight loss therapy and weight maintenance program. . . ."1
Thus, we wanted to examine whether dieting patients who were randomized to
the lifestyle group would have health improvements similar to those receiving
the standard of care (diet plus vigorous exercise).
