Measuring ketone production can be a pain. I’ve recently been testing a new device called BIOSENSE® that will change this. It’s a scientifically validated, highly accurate breath ketone monitor that makes it easy to test your ketones throughout the day. I’m now recommending it to all of my patients that are fasting or doing ketogenic diets, and I’m using it myself. Check it out!

Measuring your ketones can help you do more than determine whether or not you’re in nutritional ketosis. One of the easiest ways to measure ketones is by using a ketone breathalyzer. The Biosense breath ketone monitoring system is the only clinically-backed breath ketone monitor. This device provides you with an easy and accurate way to determine whether or not you are in a state of nutritional ketosis while intermittent fasting or following a ketogenic diet.

The BIOSENSE® breath ketone meter has been an absolute game changer for me and my obsession with monitoring health data. The device is super simple to use, minimally invasive, and all of your data gets stored in an app that allows you to view your breath ketone trends over time. BIOSENSE® has allowed me to very easily test my ketone levels throughout the day without having to prick my finger or pee on a stick. Every day I feel like I am able to put this data to work to optimize my overall health and wellness.

How BIOSENSE® Works

Behind The Technology

BIOSENSE® provides a method accurate enough to replace blood measurements to track fat metabolism rate with a simple rate. How? Through our patented deep lung sampling process, which provides accurate and reproducible measurements by correcting for natural variations in exhalation time and lung capacity across individuals.

BIOSENSE® is the only breath monitor to provide this patented technology. Clinical data shows a high full-day correlation between blood and breath ketones.

Fat Burn

Only BIOSENSE® provides a full daily picture of the depth and duration of your ketosis, so you can see your true, fat metabolism rate.

Accuracy

The BIOSENSE® patented deep lung sampling technology, together with an individual factory calibration process, ensures that every device delivers precise breath ketone measurements.

Personalization

BIOSENSE® lets you set a personalized goal for your daily time and depth in ketosis, represented by the BIOSENSE® Ketone Score. This is important because research suggests that a daily Ketone Score of 120 is associated with fat loss.
