I have been using just the Ketostix since I began in January and I feel they work fine for me. My daughter who got me started on keto is a physician, and she told me from the start not to worry about the numbers (quantity of ketones) because either you’re in ketosis or you’re not, and that’s all that matters. (Kinda like you’re pregnant or you’re not.)
I think that it’s misguided effort to fixate on achieving a higher “score” because the reasons for the ketone level in the bloodstream or breath or urine can vary, depending on whether the ketones are being created from dietary fat or from body fat, also whether you are using your ketones as fuel rather than “spilling” them.
The only reason I use the sticks is to provide feedback so I can gauge whether certain changes to my diet knock me out of ketosis completely. For example, will one glass of wine do it? Will two? Will a bowl of berries with cream do it?
We are all a little different in how we respond to certain foods, and the keto stix are just one tool to help you evaluate how your body responds. For example, some folks find they can be knocked out of ketosis with some artificial sweeteners but not others (even when keeping carbs below 20). Some people do better with more protein, some with less. Further, you will go through changes as you lose weight and/or heal your metabolism.
There is no keto rule book. With that in mind, take the information you find on this forum and test it out for yourself. Leaders in the community are coming together to make the essential information available to the lay public. The more you read and watch video presentations on the research that is being done, the better you will be able to adapt your way of eating to your health journey. Here is a good example:
