We’ve talked about two types of measurements so far: mood/health and performance. Tied to that but something that is far more visible to everyone are measurements of body composition. It’s one thing to track something as subjective as how I feel each day of the experiment and trend that. It’s another thing to track overall performance over the experiment at regular intervals to see how my body is operating. However it is our body’s physical characteristics that are both the most visible and at the same time one of the important things that I want to track and trend over the experiment.
