Deciding what to eat before hitting the gym isn't always easy, but new research might help narrow down your choices. Before grabbing a pre-workout snack consider that what you put in your mouth could determine how much fat you burn while exercising. New research, involving female subjects averaging 24 years in age, shows that a low-glycemic meal causes you to burn about 50 percent more fat during your workout.
Previous studies with similar findings were focused on male and endurance athlete participants, so this new study broke new ground by focusing on women with a "typical healthy weight." Women who ate high-glycemic breakfasts before exercising burned half as much fat as the women who ate low-glycemic meals with the same caloric values. The reason? High-glycemic carbohydrates cause your blood sugar to spike sharply, while low-glycemic carbs let the body use energy for fat burning instead of blood sugar.
To maximize fat burning during your workouts, aim to consume low-glycemic meals consisting of foods like muesli, yogurt, skimmed milk, whole grains, porridge, some whole grain cereals, and soy. What do you eat in the morning before a workout?
