Why Measure Ketones?

Ketogenic diets promote healing and better health, including type 2 diabetes (T2D) reversal, weight loss, and enhanced physical performance. The clearest and easiest way to find out if your diet and exercise plan is getting you into ketosis is to measure your blood ketones. The easiest way to measure blood ketones is to measure the ketones in your breath - exactly the same way that blood alcohol is measured with a breath test.

Just as glucose measurements are critical for diabetes management, ketone measurements are the keystone metric for metabolic health and healing. Painless and inexpensive ketone measurements can provide meal-to-meal metabolic data, enabling the identification of "good" and "bad" foods and help personalize patients' diets for successful healing.
