The ketogenic diet can certainly help crossfit athletes to build endurance and reduce body weight. While carbohydrates are be a good source of fuel to be taken for high-intensity workout athletes to increase performance, the keto diet does generally not contribute to a loss in performance.

The major benefit a CrossFitter will receive from going keto is weight loss. Combining CrossFit with keto can be a very powerful way to lose weight. Not only is ketosis a proven way to shed excess body fat, but the high-intensity nature of many workouts in the sport also promotes a reduction of fat.
A keto athlete can actually replenish their glycogen from fat and protein just as fast as an athlete who is eating a carb-based diet. This idea is revolutionary to many, but it is the key reason why keto works and works especially well for CrossFit. Photos courtesy of Nic Archuleta What about building strength and muscle mass?
That is, you can eat keto/low carb and do Crossfit workouts without a drop in your performance. You’ll lose fat faster too, which is nice. If you’re already eating Keto, the results from this study should encourage you to keep going.

While carbohydrates are be a good source of fuel to be taken for high-intensity workout athletes to increase performance, the keto diet does generally not contribute to a loss in performance.
The study found that keto athletes burn mostly fat at much higher intensities than carbohydrate athletes, and keto athletes recover their muscle glycogen levels (without eating carbs) just as fast as carbohydrate-based athletes. Keto: fat for fuel. A few keto athletes even replenished their glycogen faster than the carb athletes.
What we find is that not only is there no significant difference between the keto group and the standard group on strength, but the keto group again loses significantly more fat mass, as well as seeing a slight rise in lean muscle mass. Leaner, lighter, yet just as strong. I think this is what all athletes want; to be pound for pound stronger.
Why is CrossFit so good?
CrossFit offers the benefits of stronger muscles, more efficient lungs, and an overall ability to do more work faster than you could before.
There are several benefits to going keto, many of which can be applied directly to CrossFit performance and overall health.
The ketogenic diet is a high-fat, low-carb, moderate protein nutritional approach. Like the paleo diet or zone diet, it is most commonly used by people trying to lose weight. But there are certain circumstances where people use the diet to improve performance as well.
Why is this beneficial? Because ketones use your body’s natural fat storages instead of muscle glycogen to fuel your body.
After a period of 3 to 10 days (it varies depending on the person), your liver will start producing ketone bodies (also called ketones), which your body then uses for fuel instead of glucose. Read Also: What is a Metcon Workout & 5 Conditioning Workouts for Beginners.
Many users report side effects like nausea, dizziness, fatigue, headache, constipation, and most pertinent of all, difficulty exercising when they go keto initially. This is an easy explanation—your body is used to running off one fuel source, and now you’re switching it to another.

Why should coaches use keto?
The study concludes with a statement that coaches should consider using keto for weight class sports because it is so effective with fat loss and results in no loss in performance.
Another integral aspect of CrossFit and most athlete’s favourite discipline when they get good at it. Olympic weightlifting (together with throwing) is the fourth level of the CrossFit pyramid and determines an athlete’s ability to control external objects and produce power.
The keto group saw an increase in lean body mass, as did the Western Diet group. The keto group, however, lost more body fat. During the first week of high carb for the keto group (think modified Cyclical Keto), participants saw a big increase in lean body mass, and the Western Diet group saw no change. Both groups saw the same increases in …
CrossFit is a mix of strength, gymnastics, Olympic weightlifting and endurance. We’ll delve deep into how the ketogenic diet affects CrossFit in its individual aspects and explain why it can work with all. Most of it has to do with “gluconeogenesis”. But first, let’s look at a study on Keto and CrossFit titled “ A Low Carbohydrate Ketogenic Diet …
THE KETO DIET AND ENDURANCE. Endurance is clearly very important for CrossFit, as anyone participating in the sport would know. As we know from the study on what physiological parameters impact CrossFit benchmark WOD’s, the need for a solid VO2max is important to be good at the benchmark WOD Nancy.
So, how does Keto affect gymnastics? Gymnastics Study: Keto Diet Does Not Affect Strength Performance in Elite Artistic Gymnasts.
It is obvious that you have to be strong to be good at CrossFit, so we want to find out if the keto diet is good for strength training. Let’s take a look at a couple of studies that address this topic.
How long does it take for a keto diet to work?
Once someone becomes fat-adapted, meaning they can burn and utilize fats efficiently (this can take 2-4 weeks of following the keto diet consistently), their body also becomes extremely good at making glucose internally from ingested protein, fat, and even lactic acid. This concept is called gluconeogenesis.
Just for context, CrossFit workouts generally fall in the 49-64% of VO2max range. By relying more on fat at higher intensities, the athletes were saving their limited glycogen stores for use only on those max effort bursts and burned more body fat at the same time.
Strength is a huge component of CrossFit, and people generally believe it is not compatible with keto. The facts show, however, that you can gain lean mass and strength on a keto diet to a similar degree as you can on a carb-based diet.

Inflammation can be a huge problem for the typical CrossFit athlete, as the demands of the sport are so intense. One key to adequate recovery is a quick reduction in the inflammatory response brought on by exercise.
Ketone bodies have numerous healing effects on the body, including weight loss, lowered blood sugar, improved cholesterol and triglycerides, reduced risk of heart disease, increased cognitive performance, improved neural functioning, and they can even serve as an adjuvant cancer treatment.
The ketogenic diet has increased in popularity recently — from a small niche following to the mainstream in just a few years. With more attention, though, has come more criticism. “It’s not safe or sustainable,” some have said. “It’s bad for building muscle and it’s too restrictive,” others assert.
