V2 KETOSCAN Mini Breath Ketone Meter, Diet & Fitness Tracker | Monitor Your Fat Metabolism, Level of Ketosis on Low carb, Ketogenic or Any Nutrition & Fitness Program

I've completed over a 150 tests over past few months comparing blood, breath and urine here is what I learned.First things first. There are 3 types of tests, blood, breath and urine. Blood is most accurate/most expensive/most intrusive, Breath is nearly just as accurate/expensive/least intrusive, and urine is cheapest/less accurate/kinda messy.Accuracy - More accurate than urine. KetoScan probably most accurate for fat loss. Not always as precisely lock step with blood test results, but pretty close.Ease of use - KetoScan test and app pretty good. Works great for logging notes and results. Ketoscan takes about 30-60 secs for results.Final Recommendation - If your goal is weight loss, KetoScan is perfect tool for weight loss journey. Dont hesitate to buy. For the simple reason if you burn fat, it will leave in your breathe. From what I have seen, if my breathe ketones are above 10, iI losing 2-3 lbs a week. If they are 5 or lower, losing less than 1 lb/week. This is relative to calorie restricted diet.Side note: There was a study years ago relative to your breath ketones and your breath ketones are above 10, you will lose 2.5lbs a week. If it is above 5, then 1.25lbs a week. The Ketoscan fat oz/hour numbers seem to be based off that study and seems to be true for me too.

I have been keto on and off for nearly 2 years and had started using a ketone blood meter early on in my journey. I am familiar with how my diet impacts the level of ketones my body produces and understand how to manipulate my metabolism to maximize fat burning.The breathalyzer I purchased is very accurate and has been consistent with my results from blood ketone testing. I use the Keto mojo glucose and ketone blood meter.Pros:Reliable. Testing twice in a row provided the same or similar result. Testing compared to blood meter provided a similar result. Readings of .5-1.0 mg/dL On blood meter was equivalent to 5-10 on the breathalyzer. I’ll attach images if it allows.Comes with a nice carrying pouch and extra attachments for the breathalyzer.It’s cheaper in the long run. You get 300-320 uses with the first purchase and for every replacement, 300-320 when you send it in for $30+shipping.No blood, no urine, just breath, cleaner, preferable way of testing ketone levels.Stores data in the app for you to keep track of your readings and you can take notes and upload photos with your results. It helps to remember what diet or activities promoted each respective reading.Cons:Testing with this is not as quick as blood testing. I often have to do what’s called a self-diagnostic which essentially is a pre-test before the actual testing. I have to blow into it and it takes approximately 25-30secs and then the actually test is about 15-20secs.Testing requires you to download the KetoScan app. All readings are stored in the KetoScan app using a Bluetooth connection.KetoScan is not compatible with the Fitbit App which is what I use to track and manage weight and other health information. This is probably the most disappointing. I hope more features for the app roll out overtime. You have to manually update your weight and body fat percentage for an accurate reading.You have to ship in your meter to calibrate it to get what you might consider a “refill” of breath testing at 300-320 test for $30. Cheaper but inconvenient to have to go without testing for the interim. You have to pay to ship the product back and they will pay to return the product back to you.

I have done a keto diet many times.. when you are in Keto mode, you feel it. I thought this would be a helpful tool.. participating in sports where weight class meant something , I now had bought this to assist in fat loss.. it has given extremely erratic readings on the same day.. by the time I checked what I could be doing wrong .. it was too late to return this .. and I rarely return so I am stuck with it.. Keto has a certain feel if you know your body well.. at times I dieted and did cardio to know I was full keto would get readings completely off.. followed by a completely different reading. By the time you realize this is a gadget .. it will be too late to return. Don’t waste your money, learn to understand how your body feels.. complete waste of money. My mistake was believing in it and continuing to try.. instructions were followed perfect… at that point return timeIs over.

Overall, I'm happy with the Ketoscan meter. Being the kind of person who does not want the stress of putting holes in my fingers every day or the added expense of the the lancets and strips, but wanting more information than urine strips, I find that this sits right in the middle. It give me day to day comparisons of my ketosis levels so I can see when I'm going good or bad and adjust accordingly. Probably not as accurate as analyzing the blood, but easy to adopt for daily use to see trends. Did not give it 5 stars because I find the ketoscan software to be a bit outdated.
