The Beginner’s Guide to Exogenous Ketones
Exogenous ketones. What are they and why should you pay attention to them? If you’ve been wondering what exogenous ketones are, you’re not the only one in the ketogenic dieting world who is trying to get a handle on what they are and how they can help you.
A lot of ketogenic lifestylers are looking for information on exogenous ketones and which healthy living brands (like Perfect Keto) are producing exogenous ketones to fit the keto diet seamlessly. This article will provide you with easy to understand information about exogenous ketones and beta-hydroxybutyrate – the basis of exogenous ketone supplements. With this knowledge, you’ll be able to utilize exogenous ketones in your diet, and show other keto diet practitioners how they can benefit their ketogenic diet experience.
Exogenous Ketones – The Definition
To help you out on your new ketogenic diet, here’s a simple way to understand exogenous ketones and how they can benefit your diet.
Exogenous ketones (ketone supplements) are a way to get ketones into your system without being in a state of nutritional ketosis (exogenous is from outside your body).
Nutritional ketosis is achieved inside your body by adapting your diet to a low carb, high fat diet – via nutrition to get ketones into your blood stream. Beta-hydroxybutyrate (BHB) ketones are created from nutritional ketosis and are the building block of the ketogenic diet.
Exogenous ketones, made from beta-hydroxybutyrate, is the ketone body that helps you achieve the positive results of a low carb, high fat diet. In a state of ketosis, BHB is the ketone that helps your body burn fat instead of carbs for energy.
The word exogenous describes something that is developed from external factors; something outside of the usual production. So in terms of ketones, this means that exogenous ketones are synthetic: created outside of your body by scientists and then ingested for accelerated ketosis.
We assume that you already know what ketones are, but just in case, we’ll give you a brief description of this term as well. Ketones, are organic compounds produced by in your body when your system experiences starvation, or when you restrict carbohydrates and increase fats, which inhibits a starvation-like state that produces ketone bodies.
These ketones are an ideal fuel source for your body and your brain. Studies have suggested that when your body is in a ketogenic state, it utilizes oxygen more efficiently in the generation of energy. In short, ketones are secret weapons for anyone looking to take their body’s fueling system to the next level! – Keystoketosis
Exogenous ketones are ketone supplements that are created outside of your body and taken by you as an addition to your well-defined ketogenic diet. Exogenous ketones accelerate the ketogenic diet and help you burn fat faster.
The Benefits of Exogenous Ketones
Exogenous Ketones let you be more flexible with your diet and help you reduce the strict adherence to the ketogenic diet that you may be struggling with. Exogenous Ketones help you get back into ketosis faster by speeding up the process in your body.
Exogenous ketones benefits:
- Help decrease your appetite thus helping you if you want to try intermittent fasting as part of your keto diet routine
- Benefit your mental clarity
- Boost ketone levels without having to adjust your diet
- Help you achieve the fat burning & energy producing state of ketosis faster – see research
- Help you through the keto flu symptoms by giving your body a boost of ketones
Some people may assume that if they take exogenous ketones they won’t need to adapt their diet to a low carb, high fat diet. They hypothesize that taking exogenous ketones can be a substitute for achieving nutritional ketosis.
It’s a fallacy to assume that you can add a supplement to your diet and forgo positive ketogenic diet eating habits. Don’t make this mistake. Carb restriction and a ketogenic diet are all part of the equation.
However, exogenous ketones will provide you with a kick-start to ketosis, possibly help you work through the keto flu if you are just staring a keto diet, and give you an energy boost before and after an intense work-out so that you can avoid carb-cycling.
Basically, by adding exogenous ketones to your diet, most people will achieve a positive ketogenic result and experience the same benefits and endogenous or dietary ketosis.
You can get a beta-hydroxybutyrate supplement as a way to get your body into ketosis faster and improve your ketogenic diet results – or help you over the hump of the keto flu.
Downside to Exogenous Ketones
Not everyone can handle the boost of ketones in their body. Some people may experience a GI tract upset, and some people may feel like they are too energetic, too keto adapted, and feel uncomfortable.
As with all supplements, you should ease into them over time. If you are concerned about taking a supplement, start with half a dose or less and see how it affects your body. If you are not feeling any adverse effects, add more dosage to your diet daily.
Side note: The Pefect Keto brand I mention below is featured in the podcast on Healthful Pursuit. I recommend you listen to the doctor discussing the Perfect Keto exogenous ketone supplement to understand more about the upside and downside to exogenous ketone supplements. I also tried the Perfect Keto brand vs Samsara Fitness Ketogenic BHB salts, and my review is below:
How to Leverage Exogenous Ketones for Performance
Exogenous Ketones Improve Athletic Performance
To increase your body’s ability to burn internal fuel more efficiently, you need to have a fat burning metabolism – that’s why you are on the ketogenic diet – to burn up your bodies fat stores instead of getting your fuel from carbs and garbage foods. (See our list of what to buy on the keto diet)
Metabolic efficiency refers to the degree to which fat is utilized as a fuel source at any given intensity during exercise. You may be thinking ‘ok, why do I need to know this?’. Well, if you’re an endurance athlete of any type then you probably know that excess fat doesn’t have a lot of benefits. Sure, it may add a little warmth during the winter months, but the weight of excess fat only slows you down, especially when going up hill. If only gravity didn’t exist. So most of you know that losing some fat will make you lighter (as long as you aren’t replacing it with muscle) which will decrease the effects of gravity and you will go up hill faster. This is always a good thing. – AchievePTC
By adding exogenous ketones to your diet, you can modify your diet some. A normal keotgenic diet includes a 4 to 1 ratio of fat to protein or carbohydrates. If you add exogenous ketones to your diet, some people can decrease their fat to carb/protein ratio to almost 1 to 1. This gives you a lot more room to be flexible with your ketogenic diet by adding exogenous ketones to your daily intake.
Why is this good?
Because, CHEAT DAYS… because the ketogenic diet can be difficult to maintain 24/7. Because you want to increase your body’s ability to burn fat faster and boost your energy levels and athletic performance.
Exogenous ketones are a win-win for athletic keto dieters who want an immediate boost to their bodies without waiting for nutritional ketosis to kick in.
Exogenous ketones make life a whole lot easier. Yet, don’t just start taking exogenous ketones and not test your ketosis levels as always. Be sure to experiment to find the right balance of the ketone supplement to take.
How to Take Exogenous Ketones
Exogenous ketones are excellent supplements for ketosis. You can get exogenous ketones in many forms… basically, any way you want to add exogenous ketones to your diet, you are likely to find a product that fits the bill. Like many supplements, exogenous ketones come in different forms. Liquid, powder, and pill forms are all available depending on what suits you best.
If taste is an issue, and frankly, when isn’t it?? The powdered form of exogenous ketones are the best way to get them into your diet. You can add them to drinks, shakes, smoothies, etc. It’s pretty easy to get the exogenous ketones you need with a powdered exogenous ketones supplement.
Measuring Ketone Levels in Your Body
To know the ketone levels in your blood stream you can use ketone strips or test your blood directly. Measuring ketone levels in your blood stream can be more effective and accurate than ketone strips. Most people who start using exogenous ketones notice that their ketone levels jump up a lot, faster, and stay at a more elevated level longer.
