Women

July 30, 2008 — In addition to limiting energy intake, overweight and
obese women may need to exercise 55 minutes a day, 5 days per week, to
sustain a weight loss of 10% during 2 years, according to the results
of a study reported in the July 28 issue of the Archives of Internal
Medicine.
"The importance of physical activity may be heightened in the
maintenance of clinically significant weight loss," write John M.
Jakicic, PhD, from the University of Pittsburgh in Pennsylvania, and
colleagues. "The consensus on recommendations for physical activity is
a minimum of 30 minutes of moderate intensity activity on most days of
the week, or 150 min/week. There is growing consensus that more
exercise may be necessary to enhance long-term weight loss."
Between December 1, 1999, and January 31, 2003, a total of 201
overweight and obese women with no contraindications to weight loss or
physical activity were recruited from a hospital-based weight loss
research center and randomly assigned to 1 of 4 behavioral weight loss
intervention groups according to physical activity energy expenditure
(1000 vs 2000 kcal/week) and intensity (moderate vs vigorous).
With a combination of in-person conversations and telephone calls
during the 24-month study period, participants were also encouraged to
reduce intake to 1200 to 1500 kcal/day. At baseline, body mass index
was 27 to 40 kg/m2, and age range was 21 to 45 years.
The intervention groups did not differ significantly in weight loss at
6 months (8% - 10% of initial body weight) or 24 months (5% of initial
body weight). Compared with individuals sustaining a weight loss of
less than 10% of initial body weight, those sustaining a loss of 10%
or more of initial body weight at 24 months reported performing more
physical activity (1835 kcal/week or 275 minutes/week; P < .001),
based on post hoc analysis.
"The addition of 275 minutes/week of physical activity, in combination
with a reduction in energy intake, is important in allowing overweight
women to sustain a weight loss of more than 10%," the study authors
write. "Interventions to facilitate this level of physical activity
are needed."
Limitations of this study include the amount of physical activity
based on self-report and inability to examine the additive effect of
different doses of physical activity above what could be achieved with
diet alone.
In an accompanying commentary, Warren G. Thompson, MD, and James A.
Levine, MD, PhD, from Mayo Clinic College of Medicine in Rochester,
Minnesota, note that dieting is modestly effective for the short-term
effect of obesity but that the long-term benefit is still unproven.
"Jakicic et al beautifully demonstrate that sustained weight loss
requires the continued achievement of 2000 kcal/wk of physical
activity," Drs. Thompson and Levine write. "We believe that 2000 kcal/
wk of physical activity can be achieved through a combination of
strategies, including increased formal exercise, a modified work and
school environment that allows for movement while working and
learning, and a modified home environment with less television and
more movement. Further research in sustainability of activity is
urgently needed if we are to solve the obesity epidemic."
The National Institutes of Health and the National Heart, Lung, and
Blood Institute supported this study. Dr Jakicic is on the Scientific
Advisory Board for BodyMedia, Inc, and the Calorie Control Council.
