Flow chart of experimental design. Resting energy expenditure (REE) and respiratory exchange ratio (RER) were evaluated for 30 min before each treatment on day 1 and day 5 of each experimental session. Diet induced thermogenesis (DIT) was assessed for 90 min after the consumption of either a high glycemic index (HGI) or low glycemic index (LGI) breakfast. Substrate oxidation was determined during REE, RER and DIT assessments. Subjects exercised (EXE) for 30 minutes at 85% to 95% VO2max. Blood insulin (INS), glucose (GLU), free fatty acids (FFA) were determined in the fasting state (0 min) and 30, 60, 90, 120, 130, 140 and 150 min after the consumption of test meals. Blood lactate (LAC) level was evaluated immediately before the exercise (90 minutes after the consumption of test meal) and at the 10, 20 e 30-min timepoints during the exercise.
