The company's health program consists of a $100 smart breath sensor that can detect when the body is in ketosis - a state in which it burns fats rather than sugars and carbohydrates for fuel - and a scientific smartphone app that provides personalized food and lifestyle recommendations based on an individual's physiology. The ketogenic diet - often called a "low-carb" diet - and its possible health benefits has seen increasing interest among health-conscious consumers, but traditional methods for detecting when one is in a state of ketosis have been inconvenient or expensive.
Such methods include detecting ketones using urine strips, which are messy and inaccurate, or with blood tests, which can be painful and expensive. Keyto takes a different approach by detecting a byproduct of ketone production - acetone - in the breath.
"Over the past year, the ketogenic diet has become one of the most popular diets in the United States," says David Sacks, co-founder and general partner of Craft Ventures, which led the funding round. "We believe the market is ripe for a device like Keyto, which can help people reach their goals more effectively. The Keyto team's proven track record combined with the unique form factor of its product make it a very compelling investment."
To use the Keyto breath sensor, users simply breathe into the cylindrical device and view the result on the Keyto app, which is presented as an easy-to-understand "Keyto Level" - the higher the level, the greater the state of ketosis and the more efficient the fat burn. The iOS and Android app, says the company, uses machine learning algorithms to deliver the right information at the right time to individuals based on their Keyto Level, body measurements, age, and goals.
The app includes personalized meal plans and lifestyle recommendations, a comprehensive library of ketogenic recipes, as well as educational and inspirational videos. In addition, the app features a built-in social community
