Many people lose their appetite after high-intensity exercise and can't eat anything. From a neurological point of view, in order to supply more oxygen during exercise, the body pumps blood faster, that is, sympathetic nerves are excited, and the feeling of "hunger" is dominated by parasympathetic nerves. When the sympathetic nerve is excited, the parasympathetic nerve has low excitability and is not easy to feel hungry.
