The purpose: To analyze the possibilities of usage and the dynamics of such metabolic parameters as physical rating, basal metabolism and metabolic age, in evaluating the results of liposuction. Materials and methods. The following body composition indicators were measured: physical rating, basal metabolism, and metabolic age. The study included 26 relatively healthy women before liposuction, immediately after the surgery and on the 7th day after it, which were measured with Tanita BC-542 two-electrode body composition analyzer. The significance of differences was assessed using the Wilcoxon test with an error value of p 0.05. Results. The physique rating immediately after liposuction in 3 (11%) patients improved, remaining on the 7th day, in one (4%) woman it has deteriorated. In 22 (85%) women it has not changed. The basal metabolic rate in patients on admission was 1333 (1265-1407) kcal. After liposuction it increased to 1340 (1289-1394) kcal (p = 0.02), on the 7th day - 1357 (1319-1482) kcal (p = 0.04). Metabolic age on admission in 14 (54%) patients was less than actual, in 1 (4%) woman in matched, in the remaining 11 (42%) it was more than the actual. Immediately after liposuction, the metabolic age corresponded to the actual in 6 (23%) patients, in 13 (50%) it was less than the actual age, in the remaining 7 (27%) it increased. On the 7th day the metabolic age in 16 (89%) decreased, while in the remaining 2 (11%) it did not change. On the 7th day it neither increased. Conclusions. In most patients, metabolic rates improved after liposuction, but in one case, the "deterioration" of physique rate was recorded. The procedure for measuring metabolic parameters in estimating the results of liposuction requires improvement.
