Our owner, Beto Boggiano, likes to send us peer-reviewed journal article studies that will keep us abreast of the latest research. This came through today:
We know that thin people sleep more and overweight people sleep less
(strong correlation) but here, two groups of people were put on a
restricted-cal diet to lose weight, both ate the same amt and lost
the same amount of weight but the ones that got more sleep (8.5 hrs)
lost FAT weight; the ones limited to less sleep (5.5 hrs) lost muscle
weight.
If you're trying to reduce fat mass, get your sleep.
