Re: Sleep - Ghrelin, Leptin

[Guest guest]

I saw it too and I wonder. I've also heard it before.

But the amount of sleep varies from individual to individual.

Also as people age, they need less sleep, which seems to be a normal

phenomenon.

I don't find that my appetite increases when I get less sleep. Of course,

I'm only one mouse. But so was the guy they showed in the experiment.

Maybe because instead of sleeping, they are up eating.

I think they GET less sleep, not sure they NEED less sleep. Some get less sleep because they're hungry maybe. I get less sleep because I'm getting older, and believe me I was never an early riser. I like the CST because I can sleep an hour later (ha).

Hi folks:How would this fit in with the apparent fact that, as people lose weight transitioning to CR, they find they need less sleep?Rodney.

Hi Francesca:

Yes. The 'evidence' supplied to support the proposition - that

someone restricted to four hours of sleep per night for several days

ate more each day as the 'study' progressed - was wholly

unconvincing.

Perhaps the same applies to most people when deprived of small

amounts of sleep every day for years. But perhaps it doesn't. Who

knows until they study many more people over much longer timeframes.

Perhaps this will prompt the people at the Nurses' Health Study to

take a look at their data, if hours of sleep is something they have

been keeping track of. For sure they will have the BMI data.

But I like Jeff's explanation!
