Outcome measures
Primary outcome
The primary endpoint is defined as the change in weight after two months of
intervention. The change in weight will be compared between the groups.
Secondary outcome
The secundary endpoints are the changes in body composition, physical activity
and daily energy intake after the intervention.
Background summary
There is controversy about the influences of snack consumption on energy
balance. Short term intervention studies demonstrate no energy intake
compensation, which suggests that eating in between meals result in higher
daily energy intake. Epidemiological studies however, do not show a clear
relation between snack consumption and overweight.
Study objective
The aim of the current experiment is to investigate the long term effects of
moments of snack consumption on compensation behaviour and energy balance in a
free living situation. In addition, we will focus on the effects of energy
density on energy balance.
Study design
This experiment will have a completely randomized, parallel design, with 2x2
factors: moment of consumption (either during a meal or in between meals) and
energy density (high energy density, > 12 kJ/g or low energy density, <4 kJ/g).
The low energy density group and the consumption during a meal group are
considered as reference groups. The energy content of the snacks in each study
group will be 25% of the participant*s daily energy needs. Subjects will be
randomly allocated to one of the four groups.
Intervention
Participants have to consume snacks each day for 8 weeks. Moment of consumption
is either during meals or in between meals. The food products are commercially
available. Two groups of products will be used, differing in energy density.
Study burden and risks
This intervention is non-therapeutic to the subjects. Subjects have to visit
the university on 2 days each week to collect the snacks and to measure their
body weight. Body composition, physical activity and ad libitum energy intake
will be measured at the start and at the end of the study period.
The amount of energy derived from the provided products is 25% of the energy
needs. The energy intake during the rest of the day is ad libitum, which
enables subjects to compensate for the energy consumed with the snacks.
Therefore no adverse effects are expected by participation in this experiment.
The risk associated with participation can be considered as minimal.
