%X Participants were 276 healthy overweight employees (69.2% male; mean age 44.0 years [SD 9.2]; mean BMI 29.7 kg/m2 [SD 3.1]). They were randomized to one of two intervention groups receiving a six month lifestyle intervention with behavior counseling by phone (phone group) or e-mail (Internet group), or to a control group receiving usual care. Body weight, height, waist circumference, sum of skinfolds, blood pressure, total cholesterol level and predicted aerobic fitness were measured at baseline, at 6 and at 24 months. Regression analyses included the 141 participants with complete data.At 6 months a significant favorable effect on total cholesterol level (-0.2 mmol/l, 95%CI -0.5 to -0.0) was observed in the phone group and a trend for improved aerobic fitness (1.9 ml/kg/min, 95%CI -0.2 to 3.9) in the Internet group. At two years, favorable trends for body weight (-2.1 kg, 95%CI -4.4 to 0.2) and aerobic fitness (2.3 ml/kg/min, 95%CI -0.2 to 4.8) were observed in the Internet group.The intervention effects were independent of the used communication mode. However short-term results were in favor of the phone group and long-term results in favor of the internet group. Thus, we found limited evidence for our lifestyle intervention to be effective in reducing cardiovascular risk in a group of apparently healthy overweight workers.ISRCTN04265725The prevalence of overweight (i.e., Body Mass Index [BMI] ¡Ý 25 kg/m2) and obesity (BMI ¡Ý 30 kg/m2) is high and still continues to increase. Overweight and obesity have become a worldwide epidemic, posing a considerable threat to public health [1,2]. Overweight is associated with increased risk for cardiovascular diseases and other health problems that are mainly cardiovascular risk factors [1]. In addition, it is responsible for high health care costs [3]. Therefore, early prevention of overweight and obesity is warranted.It is now globally recognized that lifestyle modification aimed at improving dietary habits and physical activi
