Keto Dieter's Breath Weapon Registered as Biological Hazard at Open-Plan Office

A commercial real estate firm in Denver was forced to evacuate its open-plan office Tuesday after the building's air quality monitoring system detected elevated levels of volatile organic compounds, a false alarm ultimately traced to the acetone-laden breath of a single employee in deep ketosis. The employee, senior analyst Brian Ketone, has been on a strict ketogenic diet for four months, consuming fewer than 20 grams of carbohydrates per day. His body, in the metabolic state known as ketosis, has been producing acetone as a byproduct of fat metabolism and expelling it through his lungs at concentrations that the building's sensors interpreted as a chemical spill. 'The alarm triggered at 2:17 PM,' said building manager Sandra HVAC. 'Our VOC sensors detected acetone levels above the threshold in the zone around workstation 47-B. Standard protocol is to evacuate and call hazmat. We evacuated 340 people. Hazmat arrived. They found Brian.' The hazmat team, outfitted in full protective equipment, traced the acetone readings to Ketone's immediate vicinity using handheld detectors. Readings decreased with distance from his desk and increased when he exhaled. 'He was the source,' said hazmat team leader Captain Diane Respire. 'His breath was registering at approximately 4 parts per million of acetone. For reference, nail polish remover is mostly acetone. This man was essentially exhaling nail polish remover. At a desk. In an open-plan office. Near the salad bar.' Ketone, who was unaware his breath had triggered the alarm, said he had noticed colleagues 'keeping their distance' in recent weeks but attributed it to 'the new cologne I'm wearing.' 'He is not wearing new cologne,' confirmed the coworker seated at workstation 47-A. 'There is no cologne. There is only the smell. It smells like a combination of overripe fruit and industrial solvent. I've been breathing through my mouth since November. My mouth is tired.' The building manager has issued a formal request that Ketone 'consider dietary modifications that do not trigger the building's emergency response systems.' Ketone has declined, noting that he has lost 30 pounds and his triglycerides have never been better. 'My macros are dialed in,' he said. 'If the building can't handle my metabolism, that's an infrastructure problem, not a diet problem.' The building's VOC alarm threshold has been adjusted upward. Ketone's neighbors have been issued desk fans.
