Background/Objectives:  Exercise performed shortly before (that is, within half a day of) a high-fat meal is beneficial for stimulating fat oxidation after the meal and reducing postprandial triglycerides (TG). This benefit of exercise is unfortunately negated if the after-exercise food choice to replace the calories expended during exercise is one containing high-glycemic index (HGI) carbohydrates. We determined the effect of consuming low-glycemic index (LGI) carbohydrates after an exercise session on fat oxidation and TG after a subsequent high-fat meal.    Subjects/Methods:  Using a randomized, counterbalanced crossover design, 23 overweight or obese individuals (body mass index ⩾25 kg m −2 ) performed: walking exercise (90 min) at 1800 h followed by no meal (EX); exercise followed by a meal with LGI carbohydrates (that is, lentils, EX-LGI); exercise followed by a meal with HGI carbohydrates (that is, instant potatoes, white bread, EX-HGI); and a control condition with no exercise or meal. After a 10-h overnight fast, participants were given a standardized high-fat meal. Fat oxidation was estimated before and for 6 h after this meal from respiratory gas measures and TG determined from blood samples.    Results:  Fat oxidation (mean±s.d.) was higher with EX (6.9±1.7 g h −1 ) than EX-HGI (6.3±1.6 g h −1 ;  P =0.007) and Control (5.9±1.7 g h −1 ;  P =0.00002), and EX-LGI (6.6±1.7 g h −1 ) was higher than Control ( P =0.002). TG total area under the curve was 18–32% lower with EX and EX-LGI compared with control ( P =0.0005 and  P =0.0001, respectively) and EX-HGI ( P =0.05 and  P =0.021, respectively).    Conclusions:  A meal containing HGI carbohydrates consumed after an evening exercise session cancels the beneficial effect of exercise for stimulating fat oxidation and lowering TG after a subsequent high-fat meal, whereas consuming a post-exercise meal with LGI carbohydrates retains the positive effect of exercise.
