The Best Keto Strips To Test Your Ketone Levels

In recent years, the keto diet has become a worldwide sensation. With millions of online articles, books, and instagram stories about how “going keto” will change your life.

Of course, numerous keto diet add-on products have crept up across the market.

One of those products happens to be the increasingly popular keto strips (there is also keto meters for testing ketones). If you’re already on the keto bandwagon, you’ve no doubt heard of them.

We are going to look in depth at the top five best keto strips later, but for those of you who want to dive straight in, here’s a quick glance to the top choices:

These small strips let you know whether you’re body is in ketosis in order to meet your optimum fat loss goals.

But how do keto strips work exactly? What are the best keto stips on the market?

What Are Keto Strips?

Keto strips measure the levels of ketones in the body. More specifically, they usually look for one particular ketone, acetoacetate.

They do this by measuring the level of ketones in your urine.

You can either hold the keto strips mid-urine stream. Or alternatively, urinate into a sterile container and dip the strip in.

Within around 10-20 seconds the strip will begin to change color. After a couple of minutes it will have reached the final stage and indicate where on the ketosis scale you are.

This is done comparing against a color coded chart which we will be looking at later in this article.

Benefits of Using Ketone Strips?

The main benefit is the fact that they can indicate whether you’re actually in a state of ketosis.

If you haven’t totally eliminated carbs from the diet, it could be possible that the amount you are consuming is preventing ketones from being produced.

Equally the ketone strips work as a powerful incentive.

But there are other benefits including:


Since keto strips are so small they can easily be taken anywhere. Keep them in your purse or backpack, and as long as there is somewhere discreet to urinate, you can check your ketone levels.


Using keto strips is the cheapest way of checking ketosis.

It’s also possible to check ketone levels either through a blood or breath meter, which are more expensive options


As there are many people who have a phobia of needles or cannot stand the sight of blood, urine strips provide a way of measuring ketosis without piercing the skin.

How to Read Ketone Strips

Unlike other tests that should be evaluated by a professional, monitoring your ketosis levels can be easily achieved at home with the use of ketone strips.

They have been specifically designed to be discreet, simple and easy to use so that they can be used by anyone, anywhere.

Their design makes it simple to check your ketone levels against a simple color chart design which shows different stages of ketosis and where you fit on the scale.

Ketone Levels

Typically, ketones are measured in millimoles per liter (mmol/L). By checking the strip against a color chart, this indicates how far into ketosis you have progressed.

Ketone Strips Color Chart

All keto strip products come with a color chart included in the pack. Although they do vary between manufacturers, generally the colors range from beige through to dark purple.

Simply compare the color which has developed on the strip next to the chart to see which one is the best match.

This then has a corresponding key which expresses ketone levels in mmol/L and/or whether you are in a light, medium, or heavy state of ketosis.

As a general rule of thumb:

  • 0.6 mmol/L – 0.9 mmol/L = light ketosis
  • 1.0 mmol/L – 1.5 mmol/L = medium ketosis
  • 1.6 mmol/L – 3.0 mmol/L = heavy ketosis

What Are Normal Ketone Levels?

It’s generally agreed that a healthy person (and not in a state of ketosis) has ketone levels around 0.6 mmol/L.

Naturally, there will be some day to day differences, and of course between individuals, but it’s a fairly ‘normal’ level.

What Should Keto Levels Be to Lose Weight?

For serious weight loss, ketone levels should be above 3 mmol/L.

What Level of Ketones Indicates Ketosis?

Strictly speaking, any ketone level above 0.6 mmol/L is considered a state of ketosis. However, as mentioned above, this will only lead to small, if any, weight loss.

Best Time to Test Ketones in Urine

Ketone levels do not remain stable throughout the day. Alcohol, exercise, food and other lifestyle factors can all affect readings.

Recent studies have shown that the most reliable time to check ketone levels is first thing in the morning when the body has not been impaired by the above.

Of course, if you are considering purchasing ketone sticks, ideally, you would like a trusted source of information to know which are the best.

This is why we have taken the time to review the products currently available on the market and come up with the best keto strips we think could be a good choice for anyone looking for additional help monitoring their ketosis levels.
