In collaboration with Dr David Stensel’s group at Loughborough University, we have undertaken a series of studies that have investigated the effects of different types of exercise (aerobic or resistance) and also exercise intensity on appetite and gut hormones. We have found that aerobic exercise causes the greatest suppression of hunger and leads to a more favorable profile of appetite regulating hormones (lower ghrelin and higher PYY). In addition, we have shown that high intensity intermittent exercise produces greater appetite suppression with concomitant higher circulating PYY3-36 concentrations than energy-matched continuous exercise. We are now investigating the mechanisms underlying these gut hormone changes.
