Ketone Testing: How to Know if the Ketogenic Diet is Working

It’s a brand new decade. And it’s off to a good start! After watching your coworker Janice drop 40 pounds, you’ve finally decided to give keto a go— and what better time than January— right?! So you downloaded a sample menu plan. Watched the Keto Kickstart Masterclass. Polished off your junk food and restocked with the essentials— butter, bacon and coffee ;).

“Let’s do this!”

Tomorrow rolls around and you hop on the scale— nothin’— zero pounds lost.

Okay, no biggie. It’s only day one.”

The following day you’re SUPER strict— bulletproof breakfast, lean lunch, followed by intermittent fasting for dinner. Next morning it’s back to the scale— nothin’— not a damn pound.

“WTF?”

So Janice recommends you run to Walgreens and purchase some ketone strips. You take her advise— pee on the strip— and watch as nothing happens.

Begrudgingly, you give it another go. This day even more militant than before. That evening you bust out your strip and wait in anticipation.

“Neutral?! Forget this garbage!”

Whoa, whoa, whoa friend— pump the breaks! First off, if you actually watched the Keto Kickstart Masterclass, you would know that keto is a LOT more than bacon and butter. Second, those pee strips are basically garbage. And finally, ketosis takes a while to get into— so be patient.

“What’s the deal with ketosis anyhow?”

Let’s recap.

What is Ketosis?

Ketosis is a metabolic state in which your body uses ketones (derived from stored or ingested fat) instead of glucose (sugar and carbs), for energy.

Ketosis is basically the holy grail of keto. Meaning, if you can maintain a consistent state of nutritional ketosis— you’ve mastered keto (for the most part).

Fortunately, ketosis is not some elusive metabolic state. In fact, it’s 100% measurable. In order to know (for sure) you’re in a state of ketosis, you can simply test your ketone levels. There are 3 common methods for measuring ketone levels.

3 Ways to Measure Ketone Levels

1. Urine Testing

The first (and most common) option when it comes to measuring ketone levels is to test your urine. Urine testing involves peeing on a test strip (and often your hand) in order to measure excess amounts of ketones within the body. Urine testing may help to determine if you’re in a state of ketosis, but they aren’t always accurate. Adaptation and hydration play a major role in the outcome of your read— often resulting in misleading results

If you choose to go this route, I’d recommend the brand Perfect Keto, they run around 8 bucks on Amazon. However, if you’re impatient like me, you can always purchase an off-brand at your local Walgreens or CVS. 

2. Breath Testing

The second method of ketone testing involves your breath. You can actually measure the amount of acetone in your body by using a breath meter. However— you should know— that this is the least reliable method of ketone testing. And not one I’d personally recommend (especially if you’re a boozer).

3. Blood Testing

The third, and most reliable method of ketone testing involves drawing blood. Now don’t worry— it isn’t nearly as scary as it sounds. By squeezing a single drop of blood onto a test stick, you can test the level of beta-hydroxybutyrate in your body. Blood testing will determine whether or not you are in a state of ketosis (down to the millimole). However, blood testing is the most expensive method available.

If you’re considering keto for the long haul, or diabetic— you’re wise to invest. I’d recommend the Precision Xtra for diabetics. And Keto Mojo for the lifers. Both have great reviews. Precision Xtra is more expensive. However, it measures both beta-hydroxybutyrate and blood glucose. 

Understanding the Ketone Spectrum

Ketosis isn’t as simple as you’re in or you’re out. There’s a whole spectrum involved. Dr. Stephen Phinney, MD, PhD and Jeff Volek, PhD, RD suggest nutritional ketosis begins at molecular concentration levels of 0.5 mmol/L. Which means, once you cross the 0.5 threshold, you’re officially “in ketosis.” Now, it doesn’t stop there. Beyond “nutritional,” there are progressive zones of “optimal” or “theraputic” ketosis.

How Do You Know Which Zone is Best?

Well, that all depends on your goals.

If weight loss is your primary goal, then nutritional ketosis (0.5 mmol/L-1.0 mmol/L) is a good starting point. As your weight plateaus (or if you’re up for the challenge), aim for optimal ketosis (1.0 mmol/L-3.0 mmol/L).

Individuals seeking therapeutic benefits for medical conditions such as epilepsy, cancer, or endocrine and metabolic disorders are generally encouraged to aim for therapeutic ketosis (3.0 mmol/L -5.0 mmol/L).

Long-term keto enthusiasts or athletes may want to consider a cyclical keto diet (CKD). In which case, therapeutic ketosis (3.0 mmol/L -5.0 mmol/L) is a solid goal prior to the advancement of CKD.

Warning!

No one (no matter the goal) should aim for the ketoacidosis zone (8.5 mmol/L -10.0 mmol/L). Anything above 8.0 mmol/L moves into the danger zone. The good news is, this zone is almost impossible to reach.

Individuals with Type 1 Diabetes need to be especially cautious, because they face the potential of producing a diabetic complication called ketoacidosis. Ketoacidosis is a life threatening condition, which is why I always recommend consulting with a health care provider prior to experimenting with keto.
