Pros and Cons of Exogenous Ketones



Ketones don’t cause weight loss, they help cause ketosis.

Ketosis is a metabolic state where your body is using fatty acids for its primary source of energy. The most common misconception (perhaps due to excessive marketing claims) is that taking ketone supplements will induce immediate weight loss.

First of all, let’s be clear that your body will produce its own ketones naturally when you follow the keto diet the right way. It’s free!

If you are following a low-carb high-fat (LCHF) ketogenic diet meal plan consistently and you’re totally crushing it and you feel an abundance of energy then you don’t really need exogenous ketones. Remember exogenous ketones are supplements. Very effective at what they do, but none the less, should be supplementary to a low carb/ketogenic style of eating that is geared towards weight loss (if weight loss is the goal).

Exogenous ketones are a tool to get you into ketosis or to boost your energy levels while already in ketosis. If your motive is weight loss – exogenous ketones can get you to the beginning of your weight loss goals.

However, there are times that exogenous ketones can benefit you as you will read below.


What Are Exogenous Ketones?

Exogenous Ketones (EK) have been around since the 1960’s, even though they have only recently been made available to consumers. Scientists were studying their use back in the 60’s most notably for childhood seizure disorders.


Thankfully, today, these supplements are far more palatable than those used back then. Ketones are molecules produced in the liver from fats and are used as energy in the absence of glucose. In the average diet, glucose is the main form of energy, and when this is dramatically reduced, the body switches to fats for fuel. This is known as “Ketosis”.  Ketones are made by your own body in your liver when you follow a Ketogenic diet. These ketones are produced “endogenously” – inside your body.

If you’ve heard the term ketosis, that’s what this is referring to the body converting fat to ketones to use for energy. In this scenario, ketones are produced endogenously, meaning inside the body.

The term “exogenous” means originating from outside your body and not made in your body. They are synthesised in a lab.

Today’s ketone supplements are mostly ketone salts since they are bound to a salt for easier absorption into the body and for better stability. The ketones can be bound to any salt backbone, like sodium, calcium, or magnesium.


​Can Exogenous Ketones put you In Ketosis and Stay There?


Some people are under the impression that exogenous ketones equals weight loss.

First of all, there’s a difference between Nutritional ketosis or ketogenesis (ketone bodies being created in the liver by following a ketogenic diet) and ketonaemia (ketone bodies in the blood). Taking EK promotes ketonaemia, not nutritional ketosis.

What Does That Mean?

Exogenous Ketones can put Beta-hydroxybutyrate or ketone bodies in your blood. The result varies but a typical boost is about 30 min – 3 hours. So if you measure your blood ketone level, it will show that you are in ketosis.

After you drink EK and measure your blood ketone level after say an hour you will see the presence of ketones. However, it doesn’t guarantee that you are in nutritional ketosis and stay there.

Why? Because your ketone levels will return to your baseline.

Nutritional ketosis is the state we want to be in because that’s how you will gain all the real benefits of ketosis.

So What Does It REALLY Mean To You?

The best thing you can do for your body to get and stay in ketosis is to eat real keto foods.

But if you’re cheating on keto, EK won’t really do much. If you think you can keep eating  high carbs and just take a glass of EK to keep you in nutritional Ketosis you will be disappointed. EK will get you back into Ketosis however as has been said you will revert back down to your natural Ketogenic state unless you keep taking EK.

In other words exogenous Ketones are not a magic pilL. They are what they are designed for and that is to supplement your Keto diet when needed. “You can’t have your cake and eat it too“.

You have to follow the keto diet effectively first, then you can supplement with EK to boost your energy and increase satiety as well as other benefits mentioned below.

Exogenous ketones are ​NOT a carb blocker or a guilt eraser after you cheat on your keto diet. It is not a weight loss supplement that leads to magical weight loss either.

It is best to follow a healthy Keto diet for a while making your own ketones first and getting to a point where you know you are in nutritional Ketosis, if you feel the need for exogenous ketones for a little boost of energy before working out or to help with Satiety down the track then make the decision as to weather you need EK.

Bottom line: on any diet, food quality needs to be prioritized 100% first, not supplements. Supplements come after that as just that, supplements.

​As said earlier, there are reasons why someone would want to try EK especially to help with symptoms during the Keto Flu phase​ and other mental benefits.


Some Benefits of Exogenous Ketones


Ease Yourself into Ketosis.

The Ketogenic diet has a lot of benefits and is science backed. When coming off the standard diet which is high carb, low fat and sometimes high protein there is for most people a transition period getting into burning fat for fuel and getting into Ketosis.

This period is often referred to as the Keto Flu period because you can feel run down, lethargic, foggy, achy, and overall unwell. The keto flu is unpleasant and is a sign that the body isn’t yet efficiently in ketosis. Your tissues are looking for glucose, and you’re not producing enough ketones yet to fill in the gaps.


Exogenous ketones are effective if you have overdone it on your carb-filled foods and you want to get back into Ketosis sooner rather than later. This is most effective as long as you make sure you back off the carbs.


Your body will still need to burn the carbs before it can make its own ketones, but adding ketones can help you feel more energetic during this short process, and help avoid a longer transition period back into ketosis.



Many people on the ketogenic diet hail it as the best way they’ve found to control their hunger. Keto helps to rebalance blood sugar, ghrelin, and leptin, all of which can cause out of control hunger and cravings.

EK are good if you are intermittent fasting and you start to get hungry. Add EK in the late morning to stave off hunger until you’re ready to break your fast.



Using exogenous ketones can also help with your workouts whether they be fasted or not, they give you energy and reduce hunger, they can help you work out harder for longer. It can be a boost for more intense workouts too if you find you just don’t feel energetic or explosive in your training.

Cognitive Benefits


The brain uses up the vast majority of the energy our bodies produce. Although this energy is normally generated from glucose in the blood when glucose levels are reduced, ketones can provide 50-70% of this energy, and it’s a more efficient process

EK use can be compared to the nootropics that have been developed for optimizing focus, memory creation, and faster cognitive performance. While you may not notice this effect on a minute to minute basis if you keep a journal of “forgetful moments” you’ll find that you have fewer of them as time goes on. You’ll also find that you’re able to come up with better ideas, and your workflow is more efficient through the day


Encouraging Weight Loss (But Not What You Think!)

Some people misunderstand that exogenous ketones are weight loss supplements. They are not! Some promoters might misrepresent the products and tell you this is some kind of fat burner pills, but it’s absolutely not true.

As discussed above, exogenous ketones can help to manage hunger, which is often hard to control for those who have excess weight to lose. There can be real physiological reasons for increased hunger, or it can be tied to mental patterns and behaviors.

Being able to break these patterns of hunger that lead to overconsumption of foods can be a massive help to those who are on a ketogenic diet for the goal of losing weight.


Choosing the ketogenic way of eating can help to balance blood sugar throughout the day, avoiding the spikes and crashes that can trigger lethargy and mindless binge eating. It can help you to shift your relationship with food in a more healthy direction.

Exogenous ketones can be an integral piece to your weight loss puzzle, as they can improve triglycerides, blood glucose, and insulin response, and even help directly with weight loss when a well-formulated way of eating is followed.



Bottom line:

EK isn’t the magic pill for instant weight loss. EK triggers ketosis which is a metabolic state where your body burns fat for fuel. EK increases satiety and feeling full, and boosts energy for exercise which helps you lose weight for the long term. You should always aim for the long term and sustainable weight loss and keep the weight off for good instead of looking for a quick fix.

Performance Booster

Athletes who train harder and longer tend to have dramatically higher energy needs both for training and for competitions.

Traditionally, this energy has been gotten from sugar-laden drinks, bars, gels, and other supplements.

Since ketogenic athletes aren’t consuming all this sugar, they have to increase their energy intake some other way.

There are many exogenous ketones companies and products out there that you can try. However, my choice is Perfect Ketone Base.
