No More Guessing!

Thanks to Keyto, I finally know how my body is responding to my diet right now! It’s a powerful course correction tool. I’m a newbie to the tool but not to Keto lifestyle attempts. It’s very motivating to see my Keyto level multiple times per day and manage my food choices accordingly. Thanks to the team at Keyto and the spark of genius that brought this tool to market. Take a bow!

So easy to use

I’ve been doing keto for a few years and have never had a reliable way to make sure I was in the butter zone of Ketosis. The urine strips are not accurate, I’ve compared them after using the Keyto. Highly recommend this to anyone doing Keto.

Keyto makes keto fun!

I have never successfully stuck to a diet for more than 2-3 days in my life. I had been intrigued by the idea of ketosis and done a lot of research on fasting, and different ways to achieve ketosis. Fascinated by the device I decided to order it, and it’s one of the best decisions I’ve made. I’ve been successfully in ketosis for 4 weeks and counting, and the keyto makes it like a game! I feel so liberated being free from cyclical carb binging and the subsequents sluggish and tired feelings. My sleep has been amazing, my energy levels are returning, and I feel so focused. I know this device is helping motivate me towards this new keto lifestyle change.
