“The Hidden Flaws in How You’re Measuring Ketones (And How to Fix It)”
You’re eating 20g of carbs, drinking ketoade, and avoiding hidden sugars. But if you’re not tracking ketones accurately, you might be missing the full picture. Let’s talk about the three common ketone-tracking methods—and their pitfalls:
-
Urine Strips: Cheap but unreliable. They measure excess ketones (acetoacetate) your body isn’t using. Once you’re fat-adapted, urine strips often show false lows.
-
Breath Ketone Meters: Measure acetone in your breath. While non-invasive, results vary with hydration and breathing patterns.
-
Finger-Prick Blood Tests: The gold standard—but painful, expensive, and only captures a single moment.
Imagine driving a car with a speedometer that only works once a day. That’s keto without continuous data! Ketone levels fluctuate hourly based on meals, exercise, and sleep. A midday spike from fasting might drop after lunch, but you’d never know with spot checks.
Enter SiBio’ CKM sensor: Stick it on your arm, and it works like a glucose monitor—but for ketones. For 14 days, it logs trends, flags dips, and helps you correlate habits (like that late-night snack) with ketosis. No more wondering, “Am I still in ketosis?” Just open the app and know.
