Weight Change and Fitness
Participants in the lifestyle group lost an average of 5.5 (1.8)
kilograms, compared with 0.6 (2.2) kilograms in the control
group, resulting in a net reduction of 4.9 kilograms
(P0.001). Fourteen of 20 lifestyle participants and 2 of 23
control participants lost 10 or more pounds (4.5 kg). Heart
rate at 5 minutes of the submaximal treadmill exercise test
was significantly reduced in the lifestyle group compared
with the control group (8.6 beats per minute, P0.011),
along with concomitant reductions in RPE (1.8, net of
control group, P0.035).
