Ketostix: What are Ketostix and how do I use them?

If you’ve been reading up on keto dieting for a while, you’ve no doubt come across people talking about Ketostix (sometimes improperly spelled as ketosticks or keto sticks).  What are ketostix?  Why do you need them?  We answer all that and more in our complete guide to Ketostix and ketone urinalysis testing.

What are Ketostix?

Simply put, Ketostix are small, thin plastic strips with a small reagent area on them.  When Ketostix are dipped in urine (or passed through a stream of urine), the reagent area changes color to indicate the amount of ketones that are present in your urine.  This is an important indicator for those on ketogenic diets because it lets us know that our body has adapted to ketosis and we are doing the diet right.

Do I need to buy Ketostix?

KetostixYes and no.  Ketostix serve two very important functions for ketogenic dieters:

  • Troubleshooting:  Beginners find Ketostix useful because it is an indicator that they are doing the ketogenic diet correctly and have indeed limited their carbohydrate consumption sufficiently to force the body into ketosis, thereby starting the process of burning fat for energy instead of carbohydrates.  More advanced keto dieters use the strips to help figure out exactly how many carbohydrates they can eat before they are kicked out of ketosis.  It can also help determine how different foods affect one’s ability to stay in ketosis.  For example, some people’s bodies can handle sugar alcohols without having trouble staying in ketosis, and Ketostix can help diagnose this.
  • Psychological Motivation:  Quite simply, it feels great seeing Ketostix turn purple.  It’s a little bit of positive reinforcement that those of us on keto diets sometimes require to keep us motivated.  It might seem stupid to some, but committing to a ketogenic diet is not always an easy task, and some “proof” that your body truly is burning fat can sometimes be the little push we need to put another slice of bacon on the skillet, so to speak.

Where can I buy Ketostix?

Ketostix Ketone Urinalysis StripsKetostix are available at most pharmacies such as Walgreen’s or Duane Reade, but I prefer to purchase Ketostix online, typically via Amazon.  I have found that Amazon’s prices are cheaper than my local pharmacy, and I love the convenience of having them shipped right to my door.

If you choose to pick up Ketostix from your local pharmacy, you shouldn’t have much trouble getting them.  Most pharmacists will recognize the brand name Ketostix (made by Bayer).  If you have trouble finding this specific brand, or if the pharmacist isn’t familiar with the product, try asking for:

    I have been on a low carb diet for many years,I have included small amounts of brown rice, quinoa, sweet potato etc in my diet. i have been on a healthy diet, however I can not lost any weight, I have been told by doctors that i will not lose it as I have very high insulin levels in my blood , I am not diabetic. I am insulin resistent. I also have a fatty liver and lupus( I have maintained the lupus very well due to my diet and supplements)I got very upset when I gained yet another 7 kgs, Now for the last 12 days I have been on a ketogenic diet, and I am only 200 grms lighter. I have been exersing for the last 4 days.Yesterday afternoon I got quiet hungry and started sweating and felt light headed so i tried a ketostix and it was on number 5 very purple. Is it safe to be that high, also i weighed myself this morning and i didnt lose weight I gained 100 grms.
    Could you please give me feed back, thank you

      Mary – I have no idea if you stuck with the keto diet or not but FYI… 100grams is not even 1/4 of a pound. You can drink a pint of water and by doing so immediately increase the weight of your body by a pound. What I’m saying is basing the success of a diet on whether or not you have lost or gained weight in the grams is not the way to go. You need to be more interested in pounds or kilos and more importantly a long term progression, not a change over the space of a few days. Stick with it and record your weight in pounds over the space of a month and then review things. Weight loss is a marathon not a sprint.
      Good luck with it all! Stay positive 🙂
