> Researchers from the University of Chicago and the University of Wisconsin-Madison found that study participants consumed on average 270 calories less per day over two weeks if they slept at least one hour more than normal.

When I saw the title I suspected it was related to eating more if you slept less. I find myself doing this when I cheat myself out of a goodnight's sleep.

100%. If I sleep less I feel hungrier and justify eating more snacks or shittier food.

When I'm tired, I find myself eating in an attempt to feel better, even though hunger is not the problem. It doesn't work very well and stops helping at all as soon as I stop eating.

Yeah. "You eat less when you literally don't have time to be eating since you are sleeping"

Amazing

This is incorrect. Getting less sleep directly up-regulates appetite. It's not just more time to eat, it's increased food craving.

There is also that whole thing about testosterones levels plumetting when under-sleeping.

Also makes sense if you think about it; little opportunity for sleeping was likely an indicator of external stressors during our evolution, so up-regulatibg energy intake during those times seems reasonable.

Source it. The linked article does not make that claim

Anecdotally, I can also attest that I'm much more likely to want junk food if I haven't slept enough. Just do a quick google search for "lack of sleep hunger" and you'll see tons of articles and papers popup.
