Study hypothesis So far there haven't been a lot of studies on the effects of treatment aimed at weight reduction of overweight and obese pre-school children. There is clear evidence, however, that the combination of cognitive behavioral therapy, dietary guidance and lifestyle activity change is very effective for weight reduction in older children.

Does a multidisciplinary treatment program consisting of dietary advice, life style activity and psychological counselling, aimed at preschool overweight children, as well as their parents, influence the progression of Body Mass Index (BMI)?

Interventions Interventions will be divided in two groups: the intervention and the usual care group.

1. The intervention group will receive a three months multidisciplinary treatment program
2. The dietary intervention will consist of a normocaloric diet, based on the required daily intake for this age group, thus securing sufficient normal growth. In six meetings parents and child will receive education and advice to ameliorate their eating behaviours
3. The exercise program will focus on an active lifestyle. Children and parents will be encouraged to reduce sedentary activities. A physiotherapist will guide them once a week in a group training (ten children per group) session. The children will perform physical activity that mimics the type and intensity of elementary school exercise. These sessions will last one hour. The parents will be asked to add on an extra 60 minutes of physical activity of their own once per week, building up to every day according to the Dutch Standard of Healthy Activities
4. Parents will also receive six sessions of behavioural therapy. In these sessions they will learn to be a healthy role model, work with feasible goals and healthy rewards, sticker charts to motivate the children and keep track of the progress, change family attitudes towards healthy eating and physical activity, practical ways to remove unhealthy food triggers and the difference between hunger and cravings. These sessions are group sessions; to diminish the burden of appointments these sessions take place in the evening.

Usual Care:
In the usual care group a paediatrician will follow up the child and its parents. In a period of three months they will be seen three times, for 30 - 60 minutes. They will receive information on healthy eating behaviour and instructions to perform physical activity once per week for 60 minutes on their own, building up to every day according to the Dutch Standard of Healthy Activities.
