Both groups were asked to fill out a 3-day food record at all
time-points. All participants received detailed instructions on how
to describe their food intake accurately according to household
measurements and/or standard portion sizes. They were asked to
record all foods and drinks consumed for three consecutive days,
either from Thursday to Saturday or from Sunday to Tuesday. The
three nutrition lectures during the exercise training-phase were
based on information on dietary habits for this age group from the
National Nutrition Survey in 2002 and food-based dietary recommendations from the Icelandic Public Health Institute
[16]. Furthermore, Group 2 also received two short individual
counseling interviews and two sessions of hands-on training in a
kitchen during their 6-month exercise training session.
