The Claim

Acute total sleep deprivation does not significantly alter subjective hunger ratings or the number of food items consumed at subsequent meals in young healthy adults, despite inducing significant changes in circulating leptin levels, indicating that acute sleep restriction does not immediately drive increased appetite or caloric intake in controlled laboratory settings.

Cause and effect
1 study reviewed
In plain English

Staying up all night doesn't actually make young, healthy people feel hungrier or eat more food the next day, even though their hunger hormones change. This shows that just missing one night of sleep doesn't immediately cause people to overeat, contrary to what many people assume.

See the scientific wording

Acute total sleep loss does not significantly alter subjective hunger ratings or the number of food items consumed at subsequent meals in young healthy adults, despite significant changes in circulating leptin levels. This indicates that sleep deprivation does not immediately drive increased appetite or caloric intake in controlled laboratory settings, challenging the assumption that acute sleep restriction directly causes overeating.

What the research says

1 study
  1. Study: Leptin and hunger levels in young healthy adults after one night of sleep loss

    The study found that staying awake all night changes hunger hormones but doesn't actually make people feel hungrier or eat more right away. This suggests that stress, not just lack of sleep, is what makes us crave food.
