Acetone, a ketone body present in the breath, is a byproduct of fat metabolism. Measuring acetone with the LEVL device helps weight loss providers personalize weight loss programs with real-time fat metabolism insights.

The LEVL device was designed specifically for weight loss and uses a proprietary sensor to measure low levels of acetone and can be integrated into any weight loss program. Blood and urine ketone tests were developed to identify ketoacidosis, which occurs once ketone levels are extremely high and the blood becomes acidic. These tests are therefore not sensitive to lower levels of ketones.
