Abstract
The health consequences and the increasing incidence of obesity already in childhood present indeed a threat. The general societal prevention is not sufficient, the focus of the treatment should be in families.
The pharmacological support in children is limited to cholecalciferol and metformin, while the biologically active nutritional supplements are also important. Motivation is substantial, as well as behavioural changes in lifestyle, reduction of the caloric supply and enhancement of the energetic output.
