As happens so often this late at night, I've just had a relatively mundane eureka moment.
As I stared down at the nutrition information on a package of fake hot dogs, I realized the fat, protein, and all the rest of the good stuff was measured using the metric system. Whereas I, like any good American, measure myself in pounds.
So rather than bother with unit conversions, I've decided to start keeping track of my weight using the metric system. It should help me get a better grasp of the actual amounts I'm ingesting.
I just wanted to remind myself to find an appropriate scale.
