In overweight women, doing supervised aerobic exercise for 12 weeks is linked to eating more food overall, snacking more often, and feeling hungrier before meals while feeling less full, which may...
Mechanism
Synthesis from 1 study
After doing aerobic exercise, the body releases more hunger signals and fewer fullness signals, making women feel hungrier and less satisfied after eating. This causes them to eat more food without realizing it, balancing out the calories they burned during exercise.
Most probable mechanism
When women do regular aerobic exercise, their bodies release more hunger hormones and less fullness hormones, which makes them feel hungrier before meals and less satisfied after eating, so they end up eating more food to match the calories they burned.
Aerobic exercise increases circulating ghrelin levels, a hormone that stimulates appetite.
Aerobic exercise reduces circulating peptide YY and leptin levels, hormones that promote feelings of fullness and suppress appetite.
Altered ghrelin, peptide YY, and leptin signaling increases neural input to the hypothalamus, enhancing hunger perception and reducing satiety signaling.
Increased hunger and reduced fullness lead to higher voluntary food intake, including more frequent snacking and larger meal portions.
