Listening to them said that fasting exercise is easy to cause hypoglycemia, so every time I basically exercise for a period of time after meals, mainly because I feel weak when I don't eat. Haha, don't laugh at me.

Don't exercise immediately if you haven't finished eating. It's definitely uncomfortable. It's easy for your stomach to sag after a long time. In short, it is not good for your health. You should digest and exercise.
