Keto converts out there will know the commitment it takes to adopt the ketogenic diet. It takes sheer guts and willpower to eat just high-fat and low-to-zero-carbs for a day, let alone an extended period of time, but that’s exactly what it requires to reach that desired fat-burning state known as ketosis.
Up until recently, the only option out there for recognising ketosis were acid-measuring urine strips, which also happened to be notoriously inexact and unreliable. That is until one very resourceful San Franciscan cardiologist by the name of Ethan Weiss came along.
One of the ketones a body produces in a state of ketosis is the chemical acetone. In addition to being a very popular nail polish remover ingredient, acetone is one of the basic by-products that a body converting fat into fuel excretes in a state of ketosis.
Weiss, who had lost 9kgs through the keto diet, used this information to create something super practical for his fellow keto loyalists. Weiss re-jigged a classic alcohol breathalyzer test, which typically measures for ethanol on the breath, into one that measures for acetone. What he got was a Keyto breathalyzer, an accurate easy-to-use keto reader.
Weiss says the breathalyzer test produced some shocking results for him, and he wasn’t even trying to go keto.
“I didn’t… try to lose weight or think about losing weight. I was just trying to see if I could get my breath score to go up. And after about a week or so, I’d lost five or eight pounds,” Weiss told Business Insider. “By the end of a month, I was buying new clothes.”
The new breath test isn’t completely foolproof. It can give false readings after a person drinks alcohol (since most alcohol has a fair amount of sugar in it, keto dieters can’t have too much to drink anyway.) Keyto certainly isn’t the only keto breathalyzer on the market, either.
Weiss is confident that paired with the company’s new app, his breath test will have the edge over competition. In addition to giving breath readings, the app includes meal planning ideas, and a library of about 10,000 foods so dieters can look up whether or not the food they’re about to eat is keto-safe.
But most importantly, it gives dieters feedback quickly and painlessly. For example, one morning after Weiss inadvertently ate breaded chicken for dinner, his breathalyzer score plummeted. Weiss quickly knew the chicken wasn’t keto-safe.
Devices aren’t ready to try just yet, but should be available in early January to those who support the company’s crowdfunding campaign, at $99 a pop.
