520			_aBackground: Manipulation of macronutrient intake and exercise can alter overall energy consumption and potentially body composition. Aim: The purpose of this study was to manipulate the macronutrient content of breakfast before exercise to investigate the impact on exercise energy expenditure and postexercise energy intake (EI). Methods: Twelve active men were recruited, 11 finished the study protocol (age: 28 ± 9 years; VO2max: 56 ± 5 ml·kg−1·min−1). In a randomized crossover design, each participant completed 4 trials, 3 consisting of a specific breakfast (protein, PRO; carbohydrate, CHO; noncaloric; NON-CAL) followed in 1 h by a 45 minutes moderate intensity treadmill exercise protocol. The fourth trial consisted of breakfast and no exercise (CON). An ad-libitum lunch and food for the rest of the day were provided and assessed for EI. Measures included resting metabolic rate pre- and postbreakfast along with oxygen uptake (VO2) during and after exercise, along with hunger scales, and blood measures of glucose, insulin and plasma-PYY prebreakfast, pre-exercise, postexercise, and 60 minutes postexercise. Results: Fat oxidation was highest during exercise in the NON-CAL (0.57 g·min−1) trial with similar levels of fat oxidation between PRO (0.50 g·min−1) and CHO trials (0.48 g·min−1). Hunger was not affected by PRO intake or exercise, nor was appetite hormones and glucose. EI at lunch and dinner was not significantly different between trials. Conclusion: Pre-exercise PRO intake did not modify fat oxidation during exercise, did not lead to a larger VO2 versus CHO, nor did it attenuate EI postexercise.
