Summary

This study looked at how one session of brisk walking or jogging changes appetite-related hormones and brain responses to food pictures in 40 adults with different body weights. Participants exercised for 60 minutes while wearing a mask to measure oxygen use. Researchers measured hormones like oxyntomodulin and ghrelin from blood samples and linked them to appetite and brain activity. The goal is to better understand how exercise affects eating behavior.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
acute continuous exercise (brisk walking or jogging)
What this could lead to
If successful, this could help explain how exercise influences appetite and eating behavior, potentially guiding weight management strategies.
What could go wrong
This is a small, completed observational study with only 40 participants. Results may not apply to everyone, and it does not test a treatment or long-term effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Body mass index (BMI) between 18.5 - 24.9 kg/m2 and a waist circumference of ≤ 88 cm for women, and ≤ 102 cm for men or a BMI between 25 - 40 kg/m2 and a waist circumference of \> 88 cm for women, and \> 102 cm for men. BMI and waist circumference thresholds vary amongst ethnicities. People with a South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean family background are prone to central adiposity and their cardiometabolic risk occurs at a lower BMI. Therefore, the following BMI and waist circumference thresholds will be applied for people of South Asian, other Asian, Black African and African-Caribbean ethnicity: (1) BMI 18.5 kg/m2 to 23 kg/m2 and waist circumference of \< 90 cm for men and \< 80 cm for women; (2) BMI 23.1 kg/m2 to 40 kg/m2 and waist circumference of ≥ 90 cm for men and ≥ 80 cm for women. * Normally consumes three meals a day * Able to walk continuously for 1 hour on a treadmill * Weight stable for 3 months (\< 3kg change in weight) * Regular menstrual cycle for the last 6 months (people taking the combined contraceptive pill are eligible for the study) * Able to undergo a 45-minute MRI scan Exclusion Criteria: * Smokers (vaping is considered smoking in this study) * Known medical conditions (e.g. diabetes, heart condition) * Taking any medication which may affect the study outcomes (e.g. liraglutide, semaglutide, insulin, steroids, anti-psychotics) * Clinically diagnosed eating disorder * Previous bariatric surgery (e.g. gastric bypass, gastric band, sleeve gastrectomy) * Food allergies or intolerances, or severe dislikes to study foods * Pregnant or breastfeeding * Have recently donated blood (within eight weeks of visits 2 and 3).
