That’s a lovely thought. But I wonder what happens when you cut half an hour sleep from someone who is already sleep deprived. In my case, that sleep deficit is particularly pronounced this time of year because there are so many things to do before the holidays in addition to the regular chores of life. Deliberately cutting out more sleep strikes me as crazy.
The irony, of course, is that I’m at the age where annual weight gain is a real concern. But cutting out sleep to lose weight? Perhaps when I was as young as the men studied for this experiment, I might have been able to cut sleep. But please, come up with a more realistic solution for someone holding down a real life, with real responsibilities, and a corresponding lack of sleep.
