Measurable effects of a change in lifestyle may occur in the long term. Only overweight, not obese children benefit from the intervention, therefore more targeted programmes should be created for obese children. Furthermore, eating habits were not documented although they are a major factor of energy balance. Parents’ perception of the children’s fitness passes and possible changes of the lifestyle after the information meeting were not quantified, therefore no information is available, which key guidelines have potentially been implemented. Additionally, sustainability of the applied approach has not beenprovenyet and should be analyzed in further follow-up studies.
