Every other day oddity

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!

    Also take a look at your workouts. Days I lift weights I’m generally hungrier.

    Thanks for the comment on my blog about the HIIT program you’re going to be following. I’m going to research it out of curiosity. Can’t wait to hear how you like it.

    Hey Brandie! Thanks for the tip on workouts. I’m not working out right now but I’ll definitely keep it in mind when I start. Estimated start date on the HIIT is mid-Oct. Intense exercise isn’t recommended on my diet, Ideal Protein, especially in the first phase.
