Abstract

The aim of the study is to identify the features of the regular aerobic exercise effect, dietary diet with the intake of dietary supplements with plant components, intended for weight loss, on the reduction of body weight, fat mass, and glycemic profile of overweight women. The article presents the results of two groups of women (22 people in each) in a three-month physical fitness program to reduce excess weight, including regular exercise and adherence to dietary nutrition. Women of the first group additionally took an active substance for weight loss, containing a mixture of carnitine, chromium, arginine and guarana, green tea, citrus fruits and willow extract, women of the second group without placebo. It was found that participation in the program led to approximately the same reduction in body weight, BMI, total body fat, visceral fat and waist circumference in women of both groups. The use of a dietary supplement (fat burner) had a negative effect on glucose metabolism and insulin resistance. We attribute this result to the presence of caffeine and an especially inappropriate combination of substances in the mixture. The negative influence of a fat burner on carbohydrate metabolism revealed by us in the process of physical culture and health-improving fitness must be taken into account when organizing sports nutrition with the use of biologically active additives.
