Abstract
The Aim. The aim of the study was to develop and evaluate the effectiveness of dietary therapy in obese patients on the basis of studying the polymorphism rs9939609 of the FTO gene.
Materials and methods. 100 patients with obesity of I-III degree aged from 18 to 55 years were examined. All patients underwent genotyping using allele-specific amplification with real-time detection of results. Depending on the genotypes of the FTO gene, obese patients received different diet therapy and were divided into 3 groups: patients with the TT and AT genotype received a standard low-calorie diet, and with the AA genotype a personalized diet.
Results. It was found that a decrease in the caloric content of the diet contributed to a decrease in body weight in obese patients, mainly due to muscle mass in carriers of the genotype AT, and in carriers of genotypes TT and AA - mainly due to the fat component.
Conclusions. Thus, the carriers of the mutant allele A in the homozygous and heterozygous variant require the selection of only a personalized diet. Therefore, in the appointment of dietary therapy to obese patients, it is recommended to carry out molecular genetic studies that will not only identify individuals with increased need for personalization of dietary therapy, but also increase the effectiveness of treatment for obesity and prevent the development of its complications.
