The unique point of a Ketogenic diet is that it’s not just a ‘low carb’ diet, but a very low carb diet(less than 20g per day). When your body is completely devoid of glucose, it goes into a process called ketosis. Here, stored body fat is used up for energy as it’s converted into ketones. Hence to monitor if you’re losing weight, it’s important to measure the Ketone levels in your body.

How do you test using Keto Strips?

As your body starts producing ketones on a ketogenic diet, they will not all be used up. When your body Ketone levels increase, they are sent out through your urine instead of being stored as fat. You can measure them through a simple urine test.
By noting the colour change in the strip when it is dipped in your urine samples, you get to know about excess ketones in your body.

  • If the strips don’t change colour, it means your body isn’t into ketosis and no ketones are detected.
  • If the strips change colour, it indicates different levels of ketones in your body according to the colour.
  • A deep purple indicates the high level of ketones. If your n a Keto diet, it means you are in a state of ketosis.
  • For diabetics, it could mean a state of Ketoacidosis, and immediate medical intervention is required.

Are Keto Strips accurate?

Keto strips are accurate when you are beginning your keto diet and want to check if you are in a state of ketosis. They are not reliable in the long run once you are consistently under ketosis because the level of ketones significantly reduces in the urine during that time. Also be aware that the ketones detected are those which are in your urine and not bloodstream, so it isn’t the most reliable method.  It is useful for those with type 1 diabetes to check of you are into Ketoacidosis.
Bottom-line: While it gives a rough indication of ketones, there are more reliable methods for measuring ketones.
