I just noticed something today. It seems as if I’m not hungry one day and the next I am, lather, rinse and repeat. I wonder what drives that. The meals I have aren’t that different one day to the next. Certainly my breakfast and lunch have been exactly the same.
I recall reading something about the amount of sleep affecting appetite and/or weight. A quick web search on “lack of sleep and weight” turned up interesting articles on the role of two hormones, leptin and ghrelin. FYI: one is from the NY Times, April 26, 2010.
My simplistic understanding: Leptin is made in my fat cells and signals the brain when I feel full. Ghrelin, made in the gut, stimulates appetite. Lack of sleep creates a double jeopardy situation; it decreases leptin and increases ghrelin. Yikes, this means with reduced sleep I feel less full and want to eat more. Sleep is definitely something to pay attention to, then.
Guess I better post this and go get some beauty sleep!
