Evaluation of the effectiveness of diet therapy with protein modification in elderly patients with obesity

Abstract

Patients and methods. This study included 43 elderly patients with class I-III obesity, who were randomized into two groups: the study group (24 patients) and the comparison group (19 patients). Anthropometric and serum parameters were assessed in all patients before and after diet therapy: total protein, transaminases, triglycerides, cholesterol fractions, glucose, uric acid, potassium, calcium, magnesium, iron, vitamins A, B2, B6, B9, B12, E, C and 25(OH)D3. Patients in the study group received a modified version of the standard diet with calorie restriction up to 1700 kcal and with protein modification by including 36 g of a specialized product for 14 days. Patients in the comparison group received a variation of the standard diet with calorie restriction up to 1730 kcal. Results. In patients in the study group, there were positive dynamics of biochemical parameters (a significant decrease in the levels of total cholesterol, glucose, uric acid, an increase in serum concentrations of 25(OH) D3, vitamin E and B12, potassium, calcium, magnesium, and zinc) and body composition parameters (a significant reduction of fat mass, total fluid, a slight increase in muscle mass) against the background of diet therapy with the inclusion of a specialized food product. Conclusion. Thus, timely diagnosis and correction of eating disorders in the elderly is an important part of the prevention and rehabilitation of alimentary-dependent diseases.
