Description The article focuses on a part of the total daily energy expenditure – thermic effect of food. The objective was to identify differences between postprandial energy expenditure after administering of isoenergetic testing meals with variable macronutrient content in selected experimental group. With the use of experiment the changes in energy expenditure above resting levels during 180 min after ingesting either high protein (85 en%) or maltodextrin (100 en%) meal-replacement shakes were identified. The experimental group were healthy men (n=20, 25,4 plus/minus 3,1 y). We found that, the amount of ~ 110 g of protein ingested within 10 min caused immediate and persisting thermic effect being significantly elevated for more than 3h. It is in contrast to the maltodextrin outcome. Ingestion of ~ 120 g caused a significant thermic effect lasting ~ 150 min. Diet induced thermogenesis calculated as the percentage of the protein and maltodextrin ingested reached ~ 14 % and 8 % respectively.
