A fan of self-experimentation, Tim Ferriss tracks the effects of his dietary interventions using several biomarkers. In particular, he monitors his ketone levels, both upon waking and following exercise. Tim maintains that not everyone processes ketones to the same extent, and he prefers to tailor his ketone level to allow maximal mental clarity. He also measures fasting glucose and hemoglobin A1c, a three-month average of glucose levels, to ensure that he does not trend toward pre-diabetes. Tim also chooses to measure free testosterone and sex hormone-binding globulin along with numerous other parameters. In this clip, Tim Ferriss outlines the biomarkers that he measures routinely to make sure his health is on-track while following a ketogenic diet.
