Background. The main cause of the excessive deposition of fat is the destruction of the mechanisms controlling the expenditure of energy. Pathological increase of adipose tissue leads to disorders of the body, and lipid – carbohydrate parameters, promotes the development of vascular diseases and increases the risk of morbidity and mortality. The aim of the study is to demonstrate the impact of diet and physical activity changes in the parameters lipid-carbohydrate of adolescents.
Material and methods. The study included obese boys (n = 35), undergoing weight reduction. A low-energy diet and regular physical activity were applied. At the beginning and after four weeks were performed anthropometric measurements and indicators of the composition of venous blood was determined. In the venous blood was determined total cholesterol, HDL-cholesterol, triacylglycerols (TG), glucose and insulin. LDL-cholesterol was calculated.
Results. It was found that the applied treatment improved the lipid profile of blood. Only for triglyceride change was not statistically significant. Statistically significant was the reduction of the concentration of glucose.
Conclusions. Reduction of body mass resulted in positive changes in blood lipidogramme and reduction of waist hip ratio, which can reduce the risk of cardiovascular disease in the future. Reduction in serum insulin and glucose demonstrates improved carbohydrate metabolism and indicates a reduced risk for type II diabetes.
