RMR has it

I just learned a new weight loss term: Resting Metabolic Rate (RMR). Apparently, this is an estimate of how many calories we burn a day based on height, weight, age and gender.

By doing a quick online search, I found a calculator online and was told that my RMR is 1535 Calories per day. Further online research has taught me that this estimate isn't based on your activity level ... it is based on your body AT REST (hence the name!). This fascinates me.

When I started 50n50, my RMR was 1603 calories per day ... and as I've lost weight that has decreased as well. Makes sense. At my goal weight (145) I will be burning 1373 calories per day. Again, fascinating.

Since I don't generally spend my days in complete rest I like to think this allows me some leeway for days like yesterday (aptly named Fat Tuesday) during which I consume almost 1500 calories.
