Avalon presented KetoAir™ at the two-day London Health Optimization Summit on September 13th and 14th, 2025. During the event, attendees learned firsthand how KetoAir™ integrates into broader wellness and metabolic-health programs.

October mid-program data from the Nevada POOL/PACT Holistic Health Reset show individual improvements in metabolic health, which may be driven by better diet, exercise habits, sleep quality, and daily routines. KetoAir™ aims to play a role as a measurement and accountability tool, helping participants track daily ketone levels and stay aligned with their health goals.

“Our Q3 achievements reflect momentum for KetoAir™ as we expand into new markets and introduce solutions that meet the growing global demand for metabolic-health tools,” said Meng Li, Interim Chief Executive Officer and Chief Operating Officer of Avalon.”

The KetoAir™ breathalyzer device is owned and manufactured by Qi Diagnostics Limited, a nanosensor-based diagnostic technologies company. Intended for users pursuing ketogenic diets for weight loss, athletic performance, or therapeutic purposes, the device utilizes nano-sensor technology to provide real-time insights.
