2.3.2 Questionnaires
The participants’ height and weight were measured. BMI was computed as
the body weight (kg) divided by the square of the height (m). The
dietary intake was assessed using a 3-day food diary (2 weekdays and 1
weekend) before starting the low calorie diet and supplements and also
at the end of the study during last week. Dietary intake composition
data were analyzed by “Nutritionist 4” (First Databank Inc., Hearst
Corp., San Bruno, CA, USA). The subjects’ PAL was evaluated using the
International Physical Activity Questionnaire 25 pre
and post intervention.
