Is it good to run on an empty stomach at night?

In our lives, many of our friends are very concerned about maintaining their body shape. When their bodies start to gain weight, they may think of various ways to lose weight. Many of you may have tried running, especially at night, some people run on an empty stomach. Is this harmful to health? Today I will introduce it to you in detail!

Of course it’s not good. Although almost everyone knows that exercising on a full stomach is not good, there are two completely different opinions about exercising on an empty stomach.

Many people who are trying to lose weight or build body support running on an empty stomach. Indeed, since the blood sugar content in the body is lower when fasting, the proportion of fat used for energy during running will increase, thereby consuming more fat. However, this is also where the problem lies. Since the blood sugar level in the human body is low when the stomach is fasting, and blood sugar is the only source of energy for the brain, running on an empty stomach will further reduce the blood sugar content, causing the brain to lack the necessary energy source, which can easily lead to hypoglycemia symptoms such as dizziness, weakness in the limbs, and even fainting. Although free fatty acids in the blood can serve as a source of energy for muscles such as the myocardium, the myocardium is not very efficient in using fatty acids. Excessive amounts of fatty acids may cause various arrhythmias or even sudden death. Although there are not many such examples, the facts show that in history, there have been several famous middle-aged and elderly joggers who died suddenly after exercising on an empty stomach.

?? In addition, due to insufficient sugar content, some fat will be incompletely oxidized, eventually generating some ketone bodies. Too much ketone bodies in the body can easily cause acidosis. In addition, exercising on an empty stomach can easily make people feel hungry and may cause abdominal pain, which will affect a person's normal digestive function. Because of the above reasons, it is recommended that you do not exercise on an empty stomach. If you are used to exercising on an empty stomach, you can supplement a small amount of carbohydrates such as fruit juice, honey, etc. before exercise.

Through the above introduction, everyone should now understand that running on an empty stomach will have a bad effect on the body. In life, we must base our weight loss on good health, otherwise we will not achieve the goal of weight loss but will harm our body.
