    Abstract:
    Prevention of obesity may help reduce the morbidity and mortality from cardiovascular diseases. In Croatia, over half of adult population is overweight. Aldo the basic medical principles of healthy weight-loss programmes are well known, it is believed that mainly because of the leak of successful therapeutic approach obesity remains the most challenging changeable cardiovascular risk factor in nowadays clinical practice. Objective of this Croatian Healthy Weight Loss Programme substudy was to determine effects and differences between the intensive group and intensive individual weight-loss program on weight loss and cardiovascular risk factor. A clinical trial included 476 adults whose body mass index (BMI) was > 30 or > 28 accompanied by increased blood pressure, glucose, and cholesterol. The study participants completed either a group (n = 243) or individually-based (n = 233) 6-month weight-loss program consisting of education, low-fat diet, pharmacological treatment with orlistat, psychological counselling, and exercise. Body weight, body mass index, blood pressure, blood sugar, and blood cholesterol were measured in all participants after 3 and 6 months. The average weight loss was 12.2 (13%) kg and 7.6 (9%) kg in the group and individual program, respectively. Beside the weight reduction, the levels of blood cholesterol, glucose, and blood pressure were also significantly reduced in comparison with baseline, decreasing to normal values in all participants (P < 0.001 for all). Decrease in the monitored parameters was greater in participants in the group program. The weight loss program provided a healthy loss of extra weight in the period of 6 months. The group program produced greater decrease in body weight, body mass index, blood pressure, glucose, and cholesterol than the individual program.
