What Are Ketones? Ketones 101

The ketogenic diet is really popular these days. It helps people lose tons of weight quickly by tricking the human body into using its own ketone bodies for energy instead of glucose. But what are ketone bodies? How does the body use them for energy? And why are they a better source of fuel compared to glucose? We'll answer all of these questions and more below.

Ketones are Energy

There are a lot of similarities between ketone bodies and glucose. Both molecules can be burned for energy by the mitochondria in your cells. Both can be disassembled, reassembled, and created from other building blocks by various organs in your body. But one main difference between the two is that ketones come from stored body fat and fatty acids, whereas glucose comes from carbohydrates, sugar, and amino acids (via gluconeogenesis).

If you have both glucose and ketone bodies floating around in your bloodstream at the same time, your body will usually choose to burn the glucose first. This is especially true for most of your brain cells. But this isn't because glucose is necessarily a better energy source. It is easier and cheaper for the body to burn glucose for energy than it is ketone bodies. This confuses some people into believing that glucose is the body's "preferred" source of energy.

But saying that glucose is the body's preferred fuel is like saying that diesel is the planet's preferred petroleum product. Obviously, diesel fuel is terrible for the planet; we only burn it in large quantities because it's cheaper, easier, and more convenient than using alternative, lower emission fuels. Likewise, ketone bodies burn cleaner and produce fewer toxic byproducts than glucose. But it's harder to make ketones, and it's a little more difficult to pull them apart and burn them for energy. This is why you have to force your body into ketosis either via fasting or a high fat, low carbohydrate diet (but more on that in a minute).

How to Get More Ketones

There are three main ways you can get more ketones into your system. The first method we're going to discuss is fasting. There are many different types of fasting, but they can be broken down into two categories: intermittent fasting, and prolonged fasting. Prolonged fasting is any water-only fast which lasts for longer than 24 hours. When you fast for extended periods of time, your need for energy doesn't go away. In order to supplement your energy needs, the body is forced to break down its own stored fat and to transform those fatty acids into ketone bodies. The effect is largely cumulative; the longer you fast, the better your body gets at converting its own stored fat into energy.

Then there's intermittent fasting. Intermittent fasting usually involves limiting your meals down into a narrower daily eating window (for example, between the hours of noon and 8 pm for a 16/8 daily intermittent fasting protocol). The easiest way to intermittent fast is to skip breakfast, and to put your lunch off as late as possible. And if you eat a high satiety diet right along with it, most people find that narrowing their food window down to 8 hours a day or less is virtually effortless.

So what is a high satiety diet? In short: the ketogenic diet. If you eat high amounts of fat and closely regulate your carbohydrate intake down to 50 net carbs or less per day, you train your body to stop relying on glucose for energy and to start relying on ketone bodies instead. Your body will still produce any extra glucose it needs via gluconeogenesis as long as it has amino acids (from the protein you eat) to make the glucose from. But once you get used to feeding your body ketones instead of glucose, your body will start to reach for the ketones first, even when it is given a choice. When this happens, you are "fat adapted". Being fat adapted means that:

Most people start a ketogenic diet because they have been told by a friend or family member that it is a quick and easy way to lose weight. But once their bodies become fat adapted, most people stick with such diets long after they're still necessary for their original purpose. But the tricky part is getting started. Luckily, there are some supplements out there designed with ketones in mind to help make the process easy and effortless, no matter who you are.

Ketone-Boosting Supplements You Should Try


The best ketogenic supplements out there contain pure BHB ketones, and that's it. Some supplements will try to razzle-dazzle you with some complicated sounding ingredients, or they'll just stuff a bunch of caffeine into their formula to boost your heart rate and burn more calories that way. But a solid, high quality ketone supplement will contain exogenous BHB ketones and nothing else. One such supplement is Keto XS.

There are two reasons to take an exogenous ketone supplement like Keto XS: to help get you started on a ketogenic diet, and to help you maintain progress if you go a little overboard on a cheat day. In the beginning of a ketogenic diet, supplementing with ketones helps encourage your body to burn them as an alternative fuel source and speeds up the fat adaptation process. This means you get to skip the keto flu line and go straight to the fun part: higher cognitive function, fast weight loss, and a massive boost in energy levels. If you take exogenous ketones after eating a few too many carbs, it'll also help you stay in ketosis so that you spend as little time out of fat burning mode as possible.

If you're interested in seeing the powerful benefits that ketones can have for your body, we strongly suggest you give Keto XS a try and order your supply today.
