Wearables & Biomarkers

A portable indirect calorimetry system that brings VO2max testing and resting metabolic rate measurement out of the research lab and into the gym, the wellness clinic, and the coaching studio. Each unit increase in maximal oxygen consumption (VO2max) is associated with a 45-day increase in life expectancy. That finding comes from a landmark 2018 study…

A handheld device that measures your breath CO2 concentration to determine whether your body is burning fat or carbohydrates, turning the concept of metabolic flexibility from a laboratory metric into a daily habit. Metabolic flexibility is the body’s ability to switch efficiently between burning carbohydrates and burning fat depending on fuel availability, activity demands, and…

A professional-tier breath analyzer that quantifies fat oxidation with clinical precision, bridging the gap between consumer wellness gadgets and laboratory metabolic testing. The relationship between breath acetone and fat metabolism is not a new discovery. Researchers have understood for decades that when the body shifts from glucose oxidation to fat oxidation, acetone, a volatile byproduct…

A pocket sensor that reads fat metabolism through your breath, promising to replace urine strips and finger pricks for anyone following a ketogenic diet. In healthy individuals, ketone bodies circulate at barely detectable levels: roughly 0.1 millimoles per liter of beta-hydroxybutyrate in the blood and approximately one part per million of acetone on the breath….

Every breath you exhale carries chemical signatures of your metabolic state. Biosense captures one of the most revealing: acetone, the volatile byproduct of fat metabolism. The relationship between breath chemistry and metabolic health is not a new discovery. Physicians in the early 20th century recognized that diabetic patients in ketoacidosis had a distinctive fruity odor…

Two biomarkers, one fingerstick. Measuring both glucose and ketones simultaneously reveals a metabolic picture that neither number can provide alone. The ketogenic diet has moved from the fringes of metabolic therapy into the mainstream of health optimization over the past decade. Originally developed as a treatment for pediatric epilepsy in the 1920s, the high-fat, low-carbohydrate…

What if you could predict how your blood sugar will respond to a meal before you eat it? January AI is building the technology to make that possible. The promise of continuous glucose monitoring has always been reactive. You eat a meal. You watch your glucose rise. You learn from the spike. Over time, you…

The connection between blood sugar and body weight has been studied for decades. Now AI is using real-time glucose data to guide when, what, and how much you eat. Weight management has historically operated on a simple input-output model: calories in versus calories out. But a growing body of metabolic research has revealed that the…

Data without interpretation is noise. Nutrisense bridges the gap between continuous glucose monitoring and meaningful health change by pairing sensors with registered dietitians. The wearable health technology industry has a coaching problem. Devices have become remarkably good at collecting data: heart rate every second, glucose every minute, sleep stages every night. But the gap between…

Glucose is the universal metabolic currency. Every cell in your body runs on it. Until recently, tracking it continuously was a privilege reserved for diabetics. That is changing. There is a peculiar asymmetry in modern health monitoring. We track steps, heart rate, sleep stages, and calories burned with consumer devices that cost a few hundred…
