I wonder if this netizen has the habit of dieting while exercising. Did he take 1-2 hours to keep it?
If you don't eat much and do strenuous exercise with similar body consumption, it is easy to have hypoglycemia, and after long-term exercise, muscle mass will increase and basal metabolism will also increase. I suggest you eat a little about an hour before exercise. If you still feel dizzy after exercise, see if eating some sugar can alleviate it. If relief means dizziness caused by hypoglycemia, then you can increase your diet appropriately.
