BioSense is a clinical-grade FDA-registered breath ketone monitor in a consumer-friendly design that is HSA/FSA eligible. BioSense ketone test results are reported in units called ACEs – a unit that translates parts per million (ppm) of breath acetone into a blood ketone equivalent. This Ketone Score is a summary of how long and how deeply you’ve been in ketosis on any given day. This is important because research suggests that a daily Ketone Score of 120 is associated with a fat loss rate of about 0.5 pounds/week. Follow our link to receive a $20 discount when you join the 4 STAR CLUB and use this device alongside our 4 STAR ENDURANCE metabolic efficiency workouts and private coaching to train (and eat!) smarter!
