elderly people like morning exercise, but the fasting exercise can lead to dizziness, sports hypoglycemia, and even syncope; and eating immediately after eating can lead to stomach pain, even vomiting. Therefore, it is suggested that eating a banana before the morning exercise can prevent the symptoms of hypoglycemia.
people who like to exercise in the morning must eat something that is easy to digest, such as bananas, raisins, sports drinks with high carbohydrates, and so on. And you'll have to exercise after 30 minutes.
