Keyto offers a personalized weight loss program that focuses on a low-carb, high-fat diet. The program is designed to help users lose weight effectively without experiencing hunger. It includes a 16-week course that provides a personalized lesson plan, access to a searchable food database, meal plans, recipes, and a members-only podcast. This comprehensive approach aims to educate users on core dietary principles and support them in making sustainable lifestyle changes.

A key feature of the Keyto program is the Keyto Breath Sensor, which analyzes a user's breath to determine whether they are burning fat or sugar for energy. This device helps users track their progress and ensures they are on the right path to achieving their weight loss goals. According to the company, 98% of users in their trial lost weight using the device.

Additionally, Keyto provides access to a team of experts, including a goal specialist, dietician, and personal trainer, to offer individualized support. This expert guidance, combined with the program's educational resources, aims to empower users to reach and maintain their health goals effectively.

The supplied product materials and a third-party review indicate that breath acetone can provide a non-invasive signal associated with ketosis and fat oxidation. A systematic review of self-tracking research shows that self-tracking is studied for motivation, usage, and health-related outcomes, but it does not validate this device or establish that it causes weight loss. The product-specific weight-loss result cited in the app listing is not accompanied by the underlying trial in the supplied evidence, so the program's weight-loss effectiveness remains unverified here.
