Keto Diet Guide: How to Measure your Ketones Properly – Thomas DeLauer

Ketone Ranges Overview

Below 0.5 mmol/L is not considered ketosis – at this level, you’re far away from maximum fat-burning

Between 0.5-1.5 mmol/L is light nutritional ketosis – you’ll be getting a good effect on your weight, but not optimal

Around 1.5 – 3 mmol/L is what’s called optimal ketosis and is recommended for maximum weight loss

Values of over 3 mmol/L aren’t necessary – that is, they will achieve neither better nor worse results than being at the 1.5-3 level

Higher values can also sometimes mean that you’re not getting enough food. For type 1 diabetics, it can be caused by a severe lack of insulin

Below 0.5 mmol/L

If you’re readings are too low you may need to avoid all obvious sources of carbs, but also to be careful with your protein intake

Excess protein will converted into glucose in the body – large amounts of protein can also raise your insulin levels somewhat, which compromises optimal ketosis

Between 0.5 & 3 mmol/L

Nutritional Ketosis

**1.5-3 mmol/L is the optimal range for fat burning**

Known as nutritional ketosis, a state where the body is using ketones as a fuel source efficiently and safely

In individuals without diabetes or in those with controlled diabetes, having insulin on board to maintain healthy blood sugar levels keeps ketone production in the safe range

This is achieved by reducing carbohydrate-intake to below 50 grams, because when glucose from food is limited, but blood sugars are still in a healthy range and enough insulin is present, the body will begin to burn body fat for fuel instead, producing low levels of ketones in the bloodstream

Ketones in the 1-3 mmol/l range are not acidifying the body

Over 3 mmol/L

Starvation Ketosis

Starvation ketones are simply the result of not eating enough food over the course of several hours


Because ketones are acid substances, high ketone concentrations in the blood may create acidosis

Ketoacidosis, commonly referred to diabetic ketoacidosis, is a very dangerous state where an individual with uncontrolled diabetes is effectively starving due to lack of insulin

In normal individuals, or those with well controlled diabetes, insulin acts to cancel the feedback loop and slow and stop the overproduction of ketones (insulin has a suppressant effect on ketone production)

Without this feedback loop, dangerous levels of ketones build up, acidifying the body

  1. Since this video was made:
    – The meter he shows is obsolete and they will make strips for it for a limited time only.
    – The company has a trade-in that is going on now for what you have and the new meter has more functionality and tests twice as many thing to render the result.
    – The strips for the new meter are less expensive. They are no longer a dollar, they are 80 cents now.
    – The strips are individually packed with descant for long, accurate life.
    – It is FDA approved which means it is required to fall within their guidelines for accuracy.

  2. I just bought the keto mojo GK+ (or whatever it’s called lol) and was looking up info on keto blood testing and so happy Thomas endorses the product! Hopefully it’s worth it! I wish I had found this video first and used the discount code though lol!

  3. I know that information can change as you get more info but I wish you would say that in the beginning of your video. I just watched one of your videos about this from 3 years ago and this video is giving conflicting information. It would be helpful if you would acknowledge this in the beginning… but that's just me.

  4. Stay away from the keto diet, that shit can kill you. It's only meant to be done under doctor supervision. If you want something that works and isn't dangerous, I recommend the Agoge diet plan… worked great for me 🙂

  5. You need carbohydrates in your diet, the keto diet is not sustainable. That's why I tried the Agoge diet and it worked great for me.

  6. What about mct oils effects? Are them real ketones I'm producing? Am I in real ketosis or I'll be out of ketosis right when I will stop taking them?

  7. My only regret is not trying the Agoge diet sooner, very good results. Keto really ruined me for a couple of weeks before that.

  8. Just purchased the Keto Promo bundle, which was already $20 off the regular price. But, by following Mr. DeLauer's link I saved an additional $13.64. For $75 I got the meter, strips, lancing device with lancets, and much more. Oh and shipping was free too. Thank you Thomas DeLauer for everything, especially for the link in the description that hooked me up with such a great value.

  9. Everybody is saying something else. Breath aceton level is a good or better indication for knowing if you re in ketosis and burning fat. I think your saying that to sell ketone device.

  10. As always, great information. Thank you. As far as the Mojo blood kit: $1.00 a strip is a lot of money to me, especially if you are measuring more than once a day. Wish there were other options. : (
