Table IV. Classication of lifestyles in relation to
the intensity of habitual physical activity or PAL.
Category PAL value
Sedentary or light activity lifestyle 1.40–1.69
Active or moderately active lifestyle 1.70–1.99
Vigorous or vigorously active lifestyle 2.00–2.40*
* PAL values > 2.40 are difcult to maintain over a long period
long period of time by free-living adult populations
range from about 1.40 to 2.40.
The average PAL for
both before and during Ramadan was 1.54 and 1.51,
respectively. These values were not signicantly
different from The Food and Agriculture Organisation/
World Health Organisation/United Nations
University recommendations for light activity (i.e.
1.56) for women.
Consequently, subjects of this
study are classied as having a sedentary or light
activity lifestyle either during or before Ramadan, as
shown in Table IV.
This study explores an important issue on physical
activity and lifestyle. The subjects who volunteered
in this study were young females (i.e. mean age is
21.6 years), and their being classied as having a
light activity lifestyle underlines an important health
concern. The practice of maintaining regular physical
activity is associated with the maintenance of adequate
body weight, cardiovascular and respiratory health,
tness, and a lower risk of developing chronic
diseases associated with diet and lifestyle.
energy recommendations should be accompanied
by recommendations to perform adequate amounts of
physical activity regularly. Time spent on activities
did not differ between pre-Ramadan and during
Ramadan fasting for all activities except for the time
spent on category 3, which includes praying. Muslims
spend more time praying during Ramadan, thus
the mean time spent on this type of activity was
signicantly higher compared to pre-Ramadan
periods. Results from other studies corroborate with
our ndings as well.
It is reasonable to expect that the obligation to eat
only during the night will lead to a denite change in
normal lifestyle activities, such as sleeping. However,
in this study, no signicant variation in total sleeping
time before and during Ramadan was found (category
1). These ndings were also consistent with other
studies, which reported no differences in total sleeping
In conclusion, our results demonstrate that
although no reduction in calorie intake was applied
to the subjects, Ramadan fasting contributed to weight
loss in healthy subjects. These ndings may nd an
application in weight loss programmes among subjects
complaining of obesity.
This study was funded by the Scientic Deanship at
The Hashemite University. We are grateful to the subjects
who volunteered for this study.
