The experiment was aimed at following effects of protein consumption-emphasising health-enhancing nutritional awareness education on changes in dietary habits, the resultant weight loss, and changes in the levels of total protein and protein fractions as well as variations in the activity of AspAT, A1AT and GGTP in the obese women blood. As a result of a four-month-long nutritional education course, the diet calorific value was found to be significantly reduced, as was the total protein consumption, including the consumption of animal protein. In addition, the consumption of lipids, including saturated lipids and cholesterol, as well as that of sucrose and sodium were found to have decreased as well. On the other hand, the uptake of plant protein, starch, lactose, dietary fibre, vitamins E, B1, B2, PP, B6, and C as well as mineral components (K, Ca, Mg, Cu) and liquids was observed to have increased. Those changes were accompanied by a slow, but consistent, body weight reduction (by 8.55 ±3.7 kg over the period of study; 0.50±0.21 kg/week) as well as a reduction of BMI (from 349±4.7 to 30.2±4.4) and WHR (from 0.86±0.04 to 0.80±0.05). The reduced - to the recommended levels commensurate with an appropriate body weight - consumption of total protein and animal protein was found to exert no influence on the levels of total protein and protein fractions and their per cent concentrations in blood. On the other hand, significant decreases in the activity of AspAT (from 25.3±4.6 to 13.5±4.5 IU/L) and GGTP (from 23.3±16.3 to 11.4±3.3 IU/L) were recorded. The significant increase in the blood iron content (from 83.9±37.0 to 133.8±40.7 µg/L) which ensued without any iron supplementation demonstrates a potential for improved iron absorption by increasing the amount of components active in the process.
