How does exercise affect appetite?

Exercise can have various effects on appetite, and the specific impact can depend on factors such as fitness level, body fat percentage, and individual differences in hunger cues. Research suggests that exercise can both decrease levels of the appetite-stimulating hormone ghrelin and increase levels of the appetite-suppressing hormone leptin

Exercise and appetite hormones

Exercise has been found to affect appetite hormones, such as ghrelin and peptide YY. Ghrelin is a hormone that stimulates appetite, while peptide YY suppresses appetite. Studies have shown that exercise, particularly aerobic exercise like running, cycling, and swimming, can lower levels of ghrelin and raise levels of peptide YY, leading to a temporary reduction in appetite

Gender differences

It's worth noting that there may be gender differences in how exercise affects appetite. Some research suggests that physical activity may raise concentrations of appetite-stimulating hormones like insulin and leptin more in women than in men

Exercise intensity and duration

The intensity and duration of exercise can also play a role in its effect on appetite. Vigorous intensity exercise, such as running or high-intensity interval training, has been found to reduce the hunger hormone ghrelin

Conclusion

In summary, exercise can have a temporary suppressive effect on appetite, particularly through the reduction of ghrelin and the increase of peptide YY. However, the relationship between exercise and appetite is influenced by various factors, including fitness level, body fat percentage, and individual differences. It's important to listen to your body's hunger cues and make sure to fuel yourself adequately before and after exercise to support your overall health and well-being.
