The Claim

Sleep restriction for 8 days does not significantly alter circulating levels of the appetite-regulating hormones leptin or ghrelin in healthy adults, suggesting that increased caloric intake during sleep loss is not mediated by these hormones.

Source: Effects of experimental sleep restriction on caloric intake and activity energy expenditure.

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.

How it works
1 study reviewed
In plain English

If you don’t get enough sleep for 8 days, your hunger hormones don’t change much—so if you end up eating more, it’s probably not because these hormones are telling you to.

What the research says

1 study
  1. Study: Effects of experimental sleep restriction on caloric intake and activity energy expenditure.

    Even though people ate more when they slept less, their hunger hormones didn’t change — so the extra eating isn’t because their body is making them hungrier through these hormones.
