Background:  Over the last three decades the prevalence of overweight and obesity has increased dramatically among children and adolescents worldwide. As the results of animal and human studies suggest that a diet rich in fructose may be a risk factor for the development of overweight, the aim of the pilot study was to evaluate if a dietary counseling aimed at a moderate reduction of dietary fructose intake (−50% in comparison to intake at baseline) has a positive effect on the body mass index (BMI) of overweight and obese children. Methods:  Fifteen overweight or obese children aged 5–8 years were included into the 3 month dietary intervention study. At baseline and after 4 and 8 weeks children and their parents were trained to reduce fructose in the children's diet. Anthropometric parameters for calculating BMI and BMI standard deviation scores (BMI‐SDS) as well as nutritional intake were assessed at baseline, after the 12‐week intervention and after 12 week of follow up. Results:  After the 12‐week intervention children had significantly reduced their total energy, fructose, sucrose and glucose intake. BMI and BMI‐SDS were significantly reduced by 0.68 kg/m2 and 0.21, respectively, at the end of the intervention. At follow up, the BMI‐SDS was significantly lower in comparison to baseline while the BMI was only decreased by trend (P= 0.08). Conclusions:  The results of our pilot study indicate that counseling aimed towards a moderate reduction of dietary fructose and/or general sugar intake may have a positive effect on BMI in overweight and obese children.
