The Claim
A 6-month aerobic exercise program in sedentary, overweight middle-aged men reduces serum leptin by 24%, and this reduction serves as a physiological signal of energy insufficiency that drives increased appetite and energy intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In sedentary, overweight middle-aged men, six months of aerobic exercise lowers leptin levels by 24%, and this lower leptin level is associated with increased appetite and higher food intake.
See the scientific wording
A 6-month aerobic exercise program in sedentary, overweight middle-aged men reduces serum leptin by 24%, indicating a physiological signal of energy insufficiency that may drive increased appetite and energy intake.
When a person exercises regularly, their fat stores shrink because the body uses stored energy. This causes fat cells to release less of a hormone called leptin. Lower leptin levels tell the brain that the body has less energy available, which turns on hunger signals and makes the person eat more to restore energy balance.
What the research says
1 studyWhen overweight middle-aged men exercised for 6 months, their bodies made less of the 'I'm full' hormone (leptin), which likely made them hungrier and caused them to eat more, explaining why they didn’t lose as much weight as expected.
