[Diet therapy program for weight loss and assessment of its effectiveness in overweight and obese persons]

The basic method of obesity treatment is diet therapy aimed at long-term maintenance of negative energy balance by restricting the caloric intake of the diet. The aim - to evaluate the effectiveness of the diet therapy program for weight loss with the use of a complex of amino acids and glucomannan. Material and methods. To conduct the study, in accordance with the inclusion and exclusion criteria, a sample of 33 overweight or obese people was formed, of which 30 people (16 men and 14 women) took part in the study. The age of the persons included in the study ranged from 20 to 59 years (average 41.0±1.73 years), body mass index- from 26.4 to 45.5 kg/m² (average 35.5±0.8 kg/m²), waist circumference as a criterion for abdominal obesity - 110.4±2.4 cm. Participants three times a day (7.00-9.00, 12.00-14.00 and 16.00-18.00) received within 14 days 15 g of powder dissolved in 200 ml of water containing whey protein concentrate, potassium (618 mg in the form of citrate), glucomannan, taurine (290 mg), zinc (2.5 mg in the form of sulfate), vitamins B₆ (1.4 mg) and B12 (3 mcg), and 2 capsules containing L-isoleucine (340 mg), L-ornithine-alpha-ketoglutarate (290 mg), L-citrulline-DL-malate (290 mg) and L-tryptophan (80 mg). In the evening, the main meal was dinner, which included a protein dish with vegetables and herbs. The energy value of the evening meal was 400 kcal (1675 kJ), the proportion of protein, fat and carbohydrates was 40, 30 and 30%, respectively, of the calorie content of the evening meal. Results. It was shown that the use of a 14-day course of the diet therapy program to reduce body weight was accompanied by a statistically significant decrease in body weight on average 6.3% of the initial level, an improvement in body composition indicators (a rather pronounced decrease in body fat mass by 9.2%, p<0.001, with a smaller decrease in lean body mass and skeletal muscle mass, respectively by 3.9 and 4.1%, p<0.001) and metabolic blood parameters (a decrease in serum glucose concentration, total cholesterol, triglycerides, total bilirubin and gamma-glutamyltransferase by 12.5, 15.0, 35.0, 22.8 and 34.6% respectively). Conclusion. Application of the diet therapy program for weight loss «Non-invasive liposuction» allows us to recommend its use in obese patients in order to increase the effectiveness of therapeutic and prophylactic measures in correcting excess body weight, improving the parameters of carbohydrate and lipid metabolism, and the functional state of the biliary system.
