Best Keto Test Strips

Ketosis refers to the process by which your body begins to burn fat as a fuel source instead of carbohydrates. In a healthy adult, ketosis is the result of a decreased availability of glucose because of a low-carb diet. It also is an incredibly effective way to shed some fat.

The keto diet was first introduced in the 1920s to treat epilepsy. In recent years, however, it has gained a massive following for its ability to enhance your weight-loss program. Other recorded benefits of the keto diet include enhanced athletic performance and mental clarity, in addition to improved cardiovascular health and cholesterol levels.

ketosis bodyPart of maintaining ketosis is checking your ketone levels regularly, which you can accomplish easily using ketosis strips that check your urine. But with the ever-burgeoning popularity of the keto diet, there is a horde of ketone test strips available on the market today, and all keto strips are not created equal.

In this review, we hope to help you identify the best keto strips out there, so you can measure your ketone levels quickly and accurately, thus remaining in ketosis and burning fat fast.

Quick Navigation

Why Do You Need To Measure Ketones?

The main factors influencing ketone levels is your balance of protein and carbohydrate intake and your level of physical activity. Even at rest, your body and brain need some form of energy to keep functioning. This level is known as your Basal Metabolic Rate, or BMR. When your body has low levels of carbs available for energy, it will turn to another source to keep going.

Reaching ketosis will increase your body’s production of ketone bodies to provide fat as your alternative energy source. High levels of ketones in your blood, therefore, are an indicator that your body has begun burning fat as its primary fuel source.

Higher levels of carbohydrate consumption will reduce blood-ketone levels and take you back out of ketosis. Your body naturally favors glucose over fat for energy because it’s easier to metabolize, so your body will always burn carbohydrates before burning fat.

ketosis testingTesting your ketone levels regularly with ketone test strips will allow you to make any necessary dietary adjustments to remain in ketosis [1]. So, regular testing can prevent your ketone levels from dropping too low.

Ketone testing your urine might sound more technical than just jumping on the scales to measure weight loss. But there is a difference between weight loss and fat loss, and your scale only measures total weight. It doesn’t account for water retention and the weight of muscle over fatty tissue. Water is heavy, and water retention alone can cause you to lose or gain as much as 3 pounds in a day. Similarly, muscle tissue is far denser and heavier than fatty tissue and will affect your overall weight.

The best keto strips will give you a clear indication of whether you have high ketone levels in your blood. Keeping them high guarantees that your body is burning fat.

Are Keto Strips Accurate?

There are multiple ways to measure blood ketone levels. The best method for you will depend on how often you want to check them, as well as your budget and personal preference.

  • Blood Test: This is the most accurate way to check blood-ketone levels, and you can accomplish it via the use of a blood glucose meter. If you're planning to measure regularly, though, the machine and test strips can get quite expensive. Though greater in accuracy, the finger-prick method can be more invasive as a repetitive procedure than simply using urine strips.
  • Breathalyzer: You can also check ketone levels in your breath. A breathalyzer is an accurate way to monitor up-to-the-minute ketone levels, though it does not deliver as much accuracy as using a glucose-blood monitor. A breathalyzer can, however, be an expensive initial outlay. The upside, of course, is that the device is a one-time purchase.
  • Ketone Strip: Ketone strips are thin plastic bands with an absorbent pad at the end that captures your urine to measure your ketone levels. You then measure your urine marking on the strip against a color chart (included with the strips) to get your reading. It is probably the simplest and most accessible way for keto dieters to measure ketones regularly because you can test urine as often as you like, and most ketone strips are inexpensive compared to other methods.

It’s worth noting that keto urine strips measure levels or ketones in your urine during the past few hours rather than providing up-to-the-minute accuracy. Even so, the best keto strips boast accuracy and are the simplest way to check ketone levels over the day or week.

What is the Best Time to Measure Ketones?

timing of ketone testYou can use a ketone strip to check ketone levels in your urine at any time of day. Anecdotal evidence suggests that results tend to be better just before lunch or dinner, at least two or three hours after consuming any food or drink, except water. It’s crucial to ensure optimum hydration levels when you’re on a keto diet. Carbohydrates retain three times the water molecules than protein or fats. If you are depleted of carbs, your body will not be able to store as much water. It is, therefore, essential to maintain adequate water intake.

The results of a study published in 2016, however, indicate that participants with stable ketosis had the highest levels of ketones in their urine (ketonuria) in the early morning and directly after dinner. Developing a routine of testing for ketones first thing in the morning, therefore, might give you the most reliable results.

What is the Optimal Ketone Level for Weight Loss?

If your main aim is to promote health, balanced blood glucose, and weight loss through fat-burning, experts recommend starting with light nutritional ketosis. The levels on the strips for this should read 0.5 mmol/L-1.0 mol/L. Once you have established this safely, you can aim for optimal or full nutritional ketosis, with levels on the strips displaying between 1.0 mmol/L-3.0 mmol/L.

  • Light nutritional ketosis:5 mmol/L-1.0 mmol/L
  • Optimal ketosis: 1.0 mmol/L-3.0 mmol/L.

What Are The Signs of Ketosis?

In addition to regular urine testing with keto strips, several signs indicate you’re in a state of ketosis:

  • Bad Breath: Unfortunately, this is one of the first signs you’ll experience with ketosis. It pays to be patient, though, as it will pass. In the meantime, increasing your water intake, reducing protein intake, and maintaining high standards of oral hygiene will help alleviate this symptom.
  • Weight Loss: Weight loss from fat will start to become apparent after a sustained period of elevated ketones.
  • Reduced Appetite: Appetite suppression is a common symptom of ketosis, as your body burns fat slower than the glucose from carbohydrates.
  • Increased Focus and Energy: Initially, you might experience brain fog with ketosis, as your body works hard to find another fuel source. After your body adapts, however, you may start to enjoy increased mental focus as keto dieting delivers incredibly effective brain fuel.
  • Short-Term Fatigue: In the early stages of ketosis, your body will struggle to adapt to carb depletion, again because fat is harder to metabolize than glucose. You might feel like everything is working a bit slower than you'd hoped for a while. Once your body has adapted, this will pass, and your energy levels will increase again. Many people report energy levels surpassing their levels before switching to a ketogenic diet.
  • Short-Term Decreases in Performance: Similar to fatigue, your body will be struggling to rebalance energy levels in the early days of ketosis. Any intense physical activity will put further demands on your body and drive up ketones. This increase will be reflected in any athletic training or workouts, with less impressive results and lower intensity levels. Hang tight, though, this is temporary, and you’ll be kicking it again in no time.

With all this information at hand, let’s take a look at some of what we believe are the best keto strips on the market today to check your levels.

Achieving Ketosis

Ketosis is not your body’s natural state, and it prefers to use glucose over fat as a fuel source because it’s an easier and more fuel-efficient way to keep your engine going. It can be a difficult process, therefore, to put your body into a state of ketosis, while still maintaining a healthy diet and lifestyle.

keto testing strips reviewThe primary way to trigger ketosis is to restrict carbohydrate intake. The level of restriction required will vary between individuals. This will depend on your age, weight, activity levels, insulin sensitivity and, of course, the all-important genetic influences. On average, however, ketosis will occur if you’re consuming less than 50 grams of carbohydrates a day for a minimum of three days.

Once you achieve a state of ketosis, maintaining it can be your next challenge. This is where regularly testing your urine with ketone urine strips can make things a bit simpler. Each individual will have unique reactions to food intakes and energy output. Personal monitoring of ketone levels in urine is the only way to measure which lifestyle and nutritional choices are working best for you.

If regular urine monitoring indicates that you’re struggling to maintain ketosis, you can make nutritional or exercise adjustments to help. Here are a few tips to help get back into the ketosis sweet spot.

Tips to Maintain Ketosis:

  • Minimize Carb Intake: To maintain ketosis, your carb intake must be 50 grams or fewer per day. This is generally no more than a handful of berries or a small portion of vegetables.
  • Include Coconut Oil in your diet: Coconut oil contains fats called medium-chain triglycerides (MCTs). MCTs are absorbed significantly faster than most other fats and transported directly to your liver, where they can be used as energy or converted to ketones.
  • Increase exercise intensity: Exercise increases your body’s need for fuel. When you are carb-depleted, your liver will generate more ketones to meet your needs.
  • Increase consumption of healthy fats, including coconut oil and avocado.
  • Try a short fast.
  • Maintain adequate protein intake.
