Clarity is key for ketosis monitoring. The ketogenic diet introduces the body to a new opportunity to shift the metabolic scales. Our body prefers to use carbohydrates as its main fuel source. As our diet decreases in carbs, our very resourceful metabolism turns to fat as a backup fuel. Ketones are a byproduct of this biological shift. The Nu-Therapy Ketone Breath Meter Monitoring System is calibrated to detect one of the three components of ketones in your breath for convenient Keto tracking, wherever you may be. You can now pinpoint which foods are contributing or hindering your progress towards ketosis. With fast results in seconds, take-with-you portability and no mess clean up, it provides quick, accurate tracking and clear readings. Take an illuminated approach to your Keto journey. The Nu-Therapy Ketone Breath Meter helps you conveniently check that your lifestyle and dietary choices are Keto-friendly. It’s your essential Keto diet companion. Note: Includes Ketone Breath Meter, 10 replaceable mouthpieces and User Manual. This product requires 2 AA alkaline batteries (not included).
