What Are Exogenous Ketones?

We may earn money or products from the companies mentioned in this post.

To understand the difference between exogenous and endogenous ketones is to look at the prefix of each word.

Endo-means from inside, where Exo means from outside. So…endogenous ketones are produced when we go without food for a while, causing our insulin levels to drop, turning our bodies into a fat-burning machine as our ketones rise.

Exogenous ketones on the other hand, are introduced from the outside in the form of a supplement, such as Keto/os, or some type of pill meant to throw you into a state of ketosis.

Where it gets confusing is that eating a ketogenic diet does the same thing. reducing carbs, eating moderate protein and high fat will cause your body to burn it’s own fat, instead of sugar (like it has for our entire lives) thus putting us in a natural state of ketosis.

So why take a exogenous ketone supplement? Well, say your weight loss has stalled, or you are just getting on the keto bandwagon and you need a kickstart of sorts. Exogenous ketones will get you into that state within one hour!!

Otherwise known as ketone esters or ketone salts, exogenous ketones may also help with people experiencing “keto flu” as they transition from a high to low carb diet.

They might also help with symptoms that are debilitating as they relate to hyperinsulinemia, dementia, Alzheimer’s, and epilepsy.

You must know your own metabolic state, however, before embarking on such a diet or adding in something like exogenous ketones. People with high blood glucose levels typically do not metabolize carbohydrates well.

Going without food for these folks is hard because their endogenous ketones are slower to kick in, they feel tired and hungry because their insulin levels are so high and therefore they most likely will eat sooner and not stop until they feel good again.

Folks who are sensitive to insulin may be able to go longer without eating, so a keto diet may help them feel full, keep their glucose levels normal, and insulin under control.

I fall into the second category. Sometimes I don’t even know I’m hungry until I start eating. I don’t crave carbs or sugar anymore, and I have great energy all day long. So why am I telling you all this?

My samples of therapeutic ketones I will start tomorrow

I am considering a new supplement from a company called Pruvit, in the form of a drink you mix up and consume twice a day. My weight has increased in the last few months because I fell off the wagon a few times, so I need a jumpstart to kick me back into ketosis.

Besides that, the exciting news for me is that due to my lack of exercise because of my knee, adding exogenous ketones to my already 80/20 keto diet should raise my energy levels and make me want to move more, which should in turn help me lose weight.

The other thing is, if I continue to eat a mostly low-carb, moderate protein, high fat diet in addition to the exogenous ketones, it won’t matter if I need a cheat day…supposedly it continues to keep you in ketosis regardless! That means in a sense that I can “have my cake and eat it too.”

I will keep you all posted and if anyone else wants some information on Pruvit and what their supplements can do for you, here is the link and maybe we can try this thing together and compare notes!!

One of the pioneers of this type of supplement, Dr. Dominic D’Agostino says using exogenous ketones is in essence a hack for getting your body’s own biochemistry to optimize your metabolism to reach your full potential.

“Ketone supplementation can be used to bio-hack the metabolism for increased energy, power, and endurance.” Dr. Dominic D’Agostino

This is great news for athletes and the fitness minded. For little old me however, I’m just looking to have better mental focus, drop a few pounds, and tone my body up for bathing suit season. 🙂

Is it safe to stay on an exogenous ketone supplement?

Here’s a great article that explains it better than I could by Dr Stephanie Estima on Medium.

This may be the answer to my prayers as well as others, and I’m sure that if I have good results, I’ll want to shout it to the mountain tops. If you want to join me on my journey, or even if you want to sit back and watch me do it, I welcome all your questions, and hope you will support me in my efforts to becoming a better me!

  1. 🙂 I know this really works for some people. Still sticking with my Med diet as that’s what works for me, but it’s interesting info to tuck away.

    1. Thanks for reading! Does your diet limit bread, pasta, and sugar? You will still get good benefits if so. 🙂

  2. With fasting, not especially. I have to be careful because of my stoma, so now I tend to go for small meals, and often when I’m more poorly I don’t eat at all or very little, so maybe that counts as fasting on occasions! x

    1. I’m sorry, I didn’t realize. Do you also have to follow a particular diet? It is amazing to me how little doctors advise their patients on how diet can help with certain conditions. So many would benefit from having a nutritionist along with their other specialists, but sometimes I think they may not tell patients this info on purpose just so they can keep on being needed. Know what I mean?

    1. Thank you! I’m excited to get started and see how much energy I’m going to have and if I’m focused or all over the place. 😊

  3. I must admit I didn’t have a clue what they were until reading this so I’ve definitely learned something new today! Interesting how these as supplements can provide a ‘kickstart’, and also the potential benefits make them worth considering..! xx

  4. Interested in your experiment with exogenous ketones! Will start tuned to see whether you feel any added benefit. Wondering: do you fast routinely at all?

    Many have trouble differentiating the effect of being in ketosis (and all the metabolic benefits they go along with being in that state) and the benefits of the ketones themselves.

    Ketogenic diet or fasting offer so many benefits… I hope those not in state of ketosis just start slamming down ketones and expect all the benefit.

    Great post, this topic needs more discussion! Looking forward to a follow-up 🙂

    1. Since being on a Keto diet I have occasionally gone without a meal because I didn’t feel hungry but I wasn’t exactly planning to fast.
      Yes, I don’t want that either, that’s why I pointed out that the exogenous ketones work to enhance the Keto lifestyle, not let just anyone enjoy the benefits and expect results. I will follow up, I promise 😊 thanks for stopping by!
