The experiment was aimed at determining effects of health-promoting nutritional education and changes in dietary habits of menopausal women and their body weight loss on the composition of their body. Fourth-month nutrition-awareness education resulted in a reduction of dietary energy content, total protein consumption (including uptake of animal protein), total fat (including saturated fats), cholesterol, sucrose, and Na. On the other hand, an increase was recorded in the consumption of plant protein, starch, dietary fibre, vitamin B₆, PP and beta-carotene as well as mineral components – K, Ca, Mg, Zn and liquid. Those changes were accompanied by slow, but steady, reduction of body weight (from 86.7±8.5 to 80.7±8.2 kg), and a reduction of BMI (from 33.3±3.5 to 31.3±3.4), WHR (from 0.87±0.09 to 0.84±0.07), and WHtR (from 0.65±0.06 to 0.60±0.06). A change in body composition involving not only a significant reduction in the fat proportion (from 46.6±5.9 to 41.8±4.1%) and an increase in the fatless body weight (from 51.3±5.3 to 57.2±3.6%) and water content (from 39.1±3.4 to 42.8±3.6%), but primarily a true reduction of the body fat content (from 38.7±7.9 to 33.3±6.7 kg), without any change in the fatless weight and water content were found as well.
