When it comes to curbing hunger, aerobic exercise, like running on a treadmill, is more effective than non-aerobic activities, such as weightlifting. So says a new study in American Journal of Physiology - Regulatory, Integrative and Comparative Physiology. Participants doing aerobic exercise had decreased ghrelin levels and increased peptide YY levels, meaning appetite was suppressed. The non-aerobic group also had lower ghrelin, but no significant change in peptide YY levels; HealthDay News reports.
Actually, sleep has a lot to do with ghrelin too. Previous research reveals not getting enough sleep boosts ghrelin levels and increases hunger and appetite, which can contribute to weight gain and obesity. Just another reason why getting sufficient sleep is a good idea!
