Re: Re: Sleep - Ghrelin, Leptin

[Guest guest]

Just an anecdote. A co-worker sleeps 2-4 hours/night, and has done so

for years. He claims it's all he needs. He works 2 or 3 jobs at a

time, shift followed by shift followed by shift. He eats everything,

especially junk food, yet stays rail thin......

There was another problem with that experiment. The guy knew that he had a

minibar stocked with all sorts of fattening (and delicious) goodies in his

room.

I think it would have worked better if they just let him ask for the foods

he wanted/craved at each meal or snacktime, instead of loading up a minibar

(which he could easily access) with " bad " foods. Too much temptation and I

don't know if I could resist it myself.
