What Are Exogenous Ketones And Should You Use Them?

Exogenous ketones are an alternative source of energy that can help with weight loss.

They work by increasing the body’s production of ketones, which are produced naturally when your body is in starvation mode and needs more energy.

Exogenous ketone supplements have been shown to increase the rate at which people burn fat cells, reduce appetite, and improve mental focus.

Exogenous refers to something that is introduced from the outside. In this case, exogenous ketones are a source of energy from an outside source that can help your body generate more ketones and break down fat cells to release fatty acids used as fuel by the brain and body.

In ancient times, people’s bodies were forced to adapt to conditions, so when food was scarce, your body would break down its own stored fat for energy.

Now, since we live in an age where the foods we eat are readily available at any hour of the day, exogenous ketones can help us enter survival mode and kick start the process of burning fat.

This article will talk about how exogenous ketones work, how to use them for weight loss, and whether or not they’re safe to use.

Ketones And Ketosis

In a ketogenic diet, you’re burning fat instead of glucose. Glucose is derived from carbohydrates in food.

Ketones are derived from fat storage in the body and they’re used for energy when glucose is not available to burn.  

When you eat a ketogenic diet and burn fat for fuel, your body will often produce more than enough ketones to power your whole body.

This is called being in a state of ketosis or being keto-adapted.  It’s the body’s natural response to starvation and a sign that your metabolism is working properly.

What Are Exogenous Ketones Used For On The Keto Diet?

The ketogenic diet uses exogenous ketones to make it easier for you to create a state of “nutritional” ketosis. They’re designed to help your body easily transition into the fat-burning state so that you develop more control over your weight loss.

Exogenous ketones are typically found in supplements because they can be used by anyone on a keto diet, regardless of their tolerance to fat.

It’s also likely that they’ll be used for those who could never get into the state of nutritional ketosis because it just wasn’t possible without taking exogenous ketones.

You may be wondering what’s the point of taking these supplements if your body can create them naturally.

The answer is that it’s not entirely known how they work in this capacity.

Some experts believe that you won’t experience similar benefits by following a keto diet without the use of exogenous ketones, but there’s no scientific evidence to back up their claims.

There are no studies that prove taking exogenous ketones alongside a ketogenic diet will result in weight loss, but it will make the process much easier for most people.

This is especially true if your body has trouble transitioning into nutritional ketosis, which is common for people who have been overweight or obese for most of their lives.

While you’re using exogenous ketones, your body is still consuming fat for energy.

Do They Decrease Appetite?

When you start burning fat for energy, your body will become a lot more sensitive to its own internal hunger signals. This is typically referred to as ketosis, and it’s why you feel less hungry throughout the day when following this type of diet.

Exogenous ketones can help with appetite control because they lower your blood glucose levels.

You may feel hungrier when you take ketones because your body isn’t using glucose for energy.

However, it’s important to note that you’re still burning fat. This means that the appetite suppressant effect should be more pronounced if you continue taking exogenous ketone supplements alongside your keto diet plan.

As long as they don’t have any adverse side effects, they shouldn’t make you hungrier. The ketone supplements are marketed to get the best of both worlds when it comes to keto dieting and appetite control.

Use exogenous ketones if you feel like your hunger levels tend to spike on low-carb diets. However, you should notice that your energy levels stay more consistent and that you’re able to focus better when you take them.

Pre-Workout Or Post-Workout?

You can also use exogenous ketones before or after a workout. Many athletes follow a ketogenic diet because it gives them the ability to push harder in their workouts, which means they’ll achieve new personal bests in the gym.

The supplements are marketed as a pre-workout supplement, but they can be useful if your workouts aren’t going as well as you hoped. If you don’t have any energy during your high-intensity training sessions or are struggling to perform at your peak, consider taking the exogenous ketones.

A study proves taking exogenous ketones before working out can lead to increased endurance and stamina. This means that you’ll be able to push your body even further in your workouts when using these supplements, which could lead to more muscle growth down the road.

How Do They Work?

Exogenous ketone supplements contain beta-hydroxybutyrate (BHB). This is the same molecule that your body creates when you’re in a state of ketosis. It’s also why exogenous ketone supplements and BHB salts may have similar effects on your body during your workout.

The goal of taking these supplements for many people is to get into a state of ketosis faster. This is especially true for people who have been trying to follow the keto diet but are experiencing issues with transitioning into this metabolic state.

These supplements can give you a short-term energy boost because of the BHB they contain, but it may not be enough to sustain your workouts if you consume them too close to starting your training.

Some people report side effects when taking exogenous ketones, but it’s typically just a mild headache that goes away after a few hours of use. If you find that you have any other adverse reactions to the supplements, discontinue their use and get in touch with your doctor as soon as possible.

How Exogenous Ketones Affect Weight Loss

Your body will use the ketone supplements you take as an alternative fuel source. By using them instead of glucose, your body can rely more heavily on fat for energy, and this will help you lose weight faster.

The ketosis that these supplements promote is a natural metabolic state where your body isn’t relying on carbohydrates for energy. When your body has to get energy from fat instead of carbs, it burns more calories even at rest. Many people who take exogenous ketone supplements report that they can’t gain weight because their bodies burn off excess calories while staying in ketosis.

Exogenous ketones are an alternative way of getting into ketosis, and you may not notice any hunger pangs by taking them. This can be helpful for people who are having a hard time transitioning into ketosis and feel ravenously hungry all the time.

You should still eat a high-fat, low-carb diet if you want to stay in ketosis, but the supplements can make it easier to transition from carbs with less of an adjustment period.

Using exogenous ketones, or taking BHB salts, can help your body enter a state of ketosis faster. However, when you take them, you’re essentially tricking your body into thinking it’s already in this metabolic state and that it needs to start using fat for energy.

This helps you shed excess weight quickly while also giving you the energy you need to excel in your workouts.

What Are the Side Effects of Exogenous Ketones?

There are many different side effects that you may experience when taking exogenous ketone supplements or BHB salts. It’s important to pay attention to these warning signs and discontinue their use if any adverse reactions occur.

The most common side effect is a headache. This should go away after taking the supplements for a few hours, but if it’s especially severe or doesn’t go away, stop using the ketone supplement and see your doctor.

The second most common side effect is gastrointestinal issues like nausea and diarrhea. Again, if this happens to you while taking exogenous ketones, discontinue their use and get in touch with your doctor right away.

Finally, you may experience some changes to your heart rate or blood pressure when taking exogenous ketone supplements or BHB salts. They’re typically still within normal ranges, but they’re worth monitoring to make sure they don’t become problematic for you.


Exogenous ketones can help you get into ketosis faster, and they may even make it easier for your body to stay there. Of course, you still have to be committed to a high-fat, low-carb diet if you want to stay in ketosis for any length of time, but taking exogenous ketone supplements can make it easier to transition into this metabolic state and lose weight fast.

Exogenous ketone supplements are still relatively new, and there’s more research to be done on what they can do for you. They may become a more popular way to drop weight fast in the future, but for now, the evidence is still inconclusive.

The best way to find out if ketone supplements are right for you is to try them out and see how they affect your weight loss efforts. You may be surprised by the results.
