An October 2024 study by University of Virginia Health System concerning ghrelin, the “hunger hormone”, associated with perceptions of hunger, said,
“We found that high intensity exercise suppressed ghrelin levels more than moderate intensity exercise,”
“In addition, we found that individuals felt ‘less hungry’ after high intensity exercise compared to moderate intensity exercise.”
“We found that moderate intensity either did not change ghrelin levels or led to a net increase,”
[that exercise above the lactate threshold] “may be necessary to elicit a suppression in ghrelin.”
“Exercise should be thought of as a ‘drug,’ where the ‘dose’ should be customized based on an individual’s personal goals,”
“Our research suggests that high-intensity exercise may be important for appetite suppression, which can be particularly useful as part of a weight loss program.”
