What Should You Eat BeforeExercising?Just before you exercise, the last thing you want to do is put a
bunch of proteins and fats into your body, even if they’re healthy
proteins and fats. These types of fuels take a long time to digest and
draw precious oxygen and energy-delivering blood into your stomach and
away from your exercising muscles. They also carry a greater risk of
giving you a stomachache during your exercise. But if you don’t eat at
all, you risk breaking down muscle and causing a great deal of stress to
your body during exercise.
