What is it: Glucose variability (GRV or GV), represented as a percentage, refers to the frequency and height of your spikes and dips in glucose throughout the day. It is calculated by looking at the ratio of the standard deviation to the mean (how much you fluctuate outside of your average range).
What are you looking for: Target variability depends on your goal. For weight loss, and metabolic health aim to keep your GRV under 15%. If you are consistently below 15% keep it up! You’ll only see added benefits. Clinical data from research studies shows that higher GRV is associated with more poor metabolic health outcomes while lower GRV is associated with increased lifespan independently of hemoglobin A1C levels.
