Since there is a link between obesity and lack of sleep, is it due to hormonal/metabolism issues, a side effect, or the behavior of those who lack sleep?

Question

Is the link due to?

1. Lack of sleep messing up metabolism and hormones or body recovery?

2. Lack of sleep being an additional problem caused by something else (Stress, overwork, bad diet, etc.), thus lack of sleep becomes more of a sign, and less of a cause, of obesity creating problems?

3. The behavior of those that lack sleep? They’re stressed out, impulsive, prolly work shitty jobs with no free time and therefore gravitate to, or are only provided, fattening junk?

4. Any combination of the three?

I read an article saying night owls die earlier and it just goes on to say “We ALL know night owls drink beer and alchohol, which causes problems” like I’ve never drunk in my life, that wasn’t a genuine study. Is there a similar thing here?

Real easy to explain. Do you move more when you feel tired or well rested? Moving more burns more calories.
