Can I run on an empty stomach in the morning?

　　A considerable number of people like to go for a long-distance run as soon as they get up in the morning to strengthen their body. But running on an empty stomach can do more harm than good. According to research by relevant experts, running on an empty stomach will increase the burden on the heart and liver, making it prone to irregular heartbeats and other phenomena. Exercise requires energy, and the body's usual source of energy is mainly carbohydrates consumed in the diet.

　　When exercising on an empty stomach, such as jogging in the morning, the main source of energy depends on fat. At this time, the free fatty acids in the blood will increase significantly. Fatty acids not only become the energy source for myocardial and other activities, but excessive amounts can also become poisons for the myocardium, causing various arrhythmias and even sudden death. People over 50 are at greater risk because their ability to utilize free fatty acids is reduced compared with younger people.

　　People who are used to long-distance running in the morning should try not to go on an empty stomach as much as possible. Before running, you can drink some honey or Grape Sugar to ensure energy and avoid disadvantages to the body.
