Exercise's effect on appetite

    Been doing a little research..

    "There are several hormones that help regulate appetite, but the researchers looked at two of the major ones, ghrelin and peptide YY. Ghrelin is the only hormone known to stimulate appetite. Peptide YY suppresses appetite."

    One study found that a 60 minute aerobic workout on a treadmill decreased ghrelin, and increased peptide YY. The same study found that 90 minutes of weight lifting decreased ghrelin, but didn't really effect peptide YY.

    This seems to make sense, at least for me, because I find that my appetite is more suppressed after sprinting, than it is after lifting weights.

      I cannot exercise on an empty stomach, it has been miserable the times that I've tried. I typically start working out at 5:30-6:00 am. I am not hungry afterwards, though if it was an especially hard strength day then I will down a protein shake that has next to no carbs in it to make certain my body has enough protein - generally I don't have a meal until 5-6 hours later.
