Hormonal

High-intensity acute exercise suppresses hunger and food intake, but this suppression is not associated with a decrease in total ghrelin concentration.

If you are tracking hormones to understand your appetite, note that total ghrelin levels may not change during high-intensity exercise even if you feel less hungry. The active form, acyl ghrelin, is likely the key driver of this suppression.
