Interleukin‐6 is not involved in appetite regulation following moderate‐intensity exercise in males with normal weight and obesity

Obesity (Silver Spring)Published Randomised crossover trial

Authors' conclusion

These results suggest that IL-6 is not involved in exercise-induced appetite suppression. Despite blunted appetite-regulatory peptide responses to MICT in participants with OB, NW participants exhibited decreased acylated ghrelin; however, no differences in appetite perceptions existed between CTRL and MICT or NW and OB.

Study context

Population
Sedentary males with normal weight and with obesity
Comparison
Moderate-intensity continuous training (MICT) vs non-exercise control, in normal weight (NW) vs obesity (OB)
  • NWn = Ninereference
  • OBn = eight
Primary endpoint
Role of IL-6 in exercise-induced appetite regulation (IL-6, acylated ghrelin, PYY3-36, GLP-1, appetite perceptions)
Follow-up
Fasted, pre exercise, and 30, 90, and 150 minutes post exercise

Primary result

As reported in the abstract

IL-6 did not moderate/mediate acylated ghrelin release after exercise
p > 0.251

Further findings

No observable effects of MICT on PYY3-36, GLP-1 or overall appetite
P > 0.334, η p 2 < 0.062
