How to know if you’re in ketosis: The best indications

A ketogenic diet is a way of eating that leads to ketosis. But what exactly is ketosis? And how do you know you are in ketosis (a.k.a. a ketogenic state)?

What is ketosis?


Ketosis, or nutritional ketosis, is the scientific name for when your body uses ketones and fat for fuel instead of carbohydrates. Typically, ketosis goes along with your body generating ketones, called ketogenesis or being in a ketogenic state.

While in a ketogenic state, your blood will have elevated levels of ketones, which are produced by your liver when your body is burning fat. Sometimes even medical professionals will associate this biological process with diabetic ketoacidosis.

Where diabetic ketoacidosis is a dangerous medical condition where extremely high levels of ketones cause the blood to become acidic, ketosis is a very common state with safe levels of ketones in the blood.  More on the differences between ketosis and ketoacidosis here.

But how do you know if you’re in ketosis?

How to know you’re in ketosis

Urine test strips

One of the most common ways of testing for the ketones are urine test strips. These are used commonly by diabetics to make sure their ketone levels are safe. These strips are easily available at most pharmacies, and are relatively affordable, making them a very simple way.

The downside is that because they specifically measure excess ketones rather than simply the presence of ketones, they are not as helpful for keto-ers who want to know whether they are in ketosis. That being said, they can be a good motivator for people that are just starting their keto journey.

Blood glucose and ketone meters

For those curious keto-ers wanting to prove they are indeed producing elevated levels of ketones, a blood test will give the most accurate results. These blood tests measure the presence of ketones, rather than measuring only the excess of ketones.

Testing for these ketones, while very similar to glucose tests, requires specific strips and a meter that can test for ketones. Most glucose meters can only test glucose. If you want a meter that can test both ketones and glucose, we recommend the Keto Mojo meter. In these blood tests, ketosis is indicated if the result is between  0.5 – 3 mmol/L.

Other indications of ketosis

If you do not have access to or do not want to use a ketone meter or urine test strips, no worries! If you pay attention, you will likely notice clear signs that you are in ketosis, whether you have a test to prove it or not.

Here are some.

  • Improved mental clarity. Your brain loves ketones, and it’s very common for people to have reduced brain fog and greater mental acuity when in a ketogenic state.
  • More energy. Many people notice increased energy when they’re in ketosis. Without the wild glucose fluctuations that standard carb-y fare will result in, energy levels remain much steadier, as well. (Goodbye, afternoon sugar crashes.)
  • Weight loss. Even if it’s slow, weight loss can be an indicator of ketosis.
  • Low-carb eating. If you are keeping your carbs very low, it’s pretty safe to assume you’re in ketosis. When first starting a keto or low-carb way of eating, it’s important to know that the time it takes for your body to adjust and enter a ketogenic state varies, anywhere from a matter of hours to days. But if you remain consistent, you can trust that your body will quickly learn to start producing those ketones.
  • Intermittent fasting. Fasting causes the body to enter ketosis, just like low-carb eating does!

What do my ketone levels mean?

One final note when it comes to ketosis and measuring ketones. If you choose to test your ketone levels, a higher number does not equate to faster weight loss, or mean that you’re doing keto “better” or that you’re deeper in ketosis.

Remember, nutritional ketosis is measured when blood ketone levels reach 0.5 – 3 mmol/L. If you are on the lower end of that range, you’re still in a ketogenic state! Never measure your success based on someone else’s results.

When I start keto, how long does it take to get into ketosis?

There’s not one single answer to this question. For some people, it might take a matter of hours. (For example, the time between dinner and breakfast.) For others, it could take several days. Factors include age, level of physical activity, metabolic health, and more. Typically, you can expect to be in ketosis within 2-4 days of cutting back significantly on carbs, but everybody is different!

The best way to stay in ketosis is to keep your carbs low. This will allow your body to continue to use your fat for fuel instead of carbs.
