The Claim
In adults aged 30–60, a polysomnographically measured total sleep time of 5 hours is associated with a 14.9% increase in fasting serum ghrelin levels compared to 8 hours of sleep, independent of BMI, age, sex, and sleep-disordered breathing, suggesting that acute sleep loss stimulates the secretion of appetite-promoting hormones.
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.
If you only sleep 5 hours instead of 8, your body might produce more of a hormone that makes you feel hungrier — even if you’re the same weight, age, or sex as someone who sleeps longer.

1 studyThis study found that people who slept only 5 hours had 14.9% more of the hunger hormone ghrelin than those who slept 8 hours, even after accounting for weight and other factors — just like the claim says.
