The ketogenic diet is a popular, low-carb, high-fat eating style that puts your body into a state of ketosis, using fat for energy instead of carbohydrates. While the keto diet can be beneficial for weight loss and boosted energy, its impact on exercise performance is less clear. Some studies suggest that the keto diet may impair athletic performance, particularly in high-intensity workouts, due to the body's reliance on fat as a fuel source. However, other research indicates that the keto diet can improve endurance and fat-burning during exercise, especially in aerobic or cardio workouts. Ultimately, the impact of the keto diet on exercise may vary depending on individual factors, and more research is needed to fully understand the relationship between keto and exercise performance.

The keto diet may impair performance in endurance athletes
The ketogenic diet has become popular among endurance athletes as a performance enhancer. However, there is limited research on its effectiveness, and the existing evidence is mixed. Some studies have found that the keto diet can impair performance in endurance athletes by affecting their energy utilization and speeding up time to exhaustion.
For example, a 2017 study found that the performance of 42 healthy adults in endurance capacity and peak power dropped after six weeks on the keto diet. Similarly, a study in elite race walkers showed that those on a ketogenic diet experienced an increase in oxygen demand at a specific speed, which negated the improvement in oxygen consumption.
The keto diet involves a significant reduction in carbohydrate intake, which can lead to lower muscle glycogen stores. This can impair exercise performance, especially in high-intensity anaerobic exercises. In addition, increased levels of ketones in the blood may increase feelings of fatigue and decrease the desire to exercise.
However, the impact of the keto diet on performance may depend on the type of exercise and the individual's genetics. Some research suggests that the keto diet could benefit endurance athletes by improving fat burning and muscle recovery. For example, a 2017 study of elite competitive walkers showed that those on a ketogenic diet increased their body's ability to burn fat during training compared to walkers on a standard diet.
Furthermore, keto athletes can benefit from higher protein intakes, as protein provides their muscles with glucose through gluconeogenesis. This can help maintain or gain muscle mass, which is important for endurance athletes. However, some versions of the keto diet may restrict protein intake, making muscle growth more challenging.

It may be beneficial for those who do aerobic-based endurance activities
The ketogenic diet is a popular, low-carb, high-fat eating style that puts the body in a state of ketosis, using fat for energy instead of carbohydrates. While the ketogenic diet can be a good way to train your body to use fat as a fuel source, it does not mean that the body will use up all the fat.
For those who do aerobic-based endurance activities, the ketogenic diet may be beneficial. This is because the body uses fat as its primary energy source during lower-intensity aerobic workouts, and since the body is fat-adapted while in a state of ketosis, there are more weight loss benefits. Continuous aerobic exercise reduces total body fat and improves fat distribution more effectively than high-intensity interval training (HIIT). Moreover, a 2017 study of elite competitive walkers showed that athletes on ketogenic diets were able to significantly increase fat burning in their bodies during training compared with walkers on a more standard diet that included carbohydrates.
However, it is important to note that ketogenic diets are often low in calories, which can make it more difficult to consume enough protein and build muscle mass. Additionally, some research has found that the ketogenic diet could negatively affect performance in endurance athletes by impairing energy utilization and speeding up time to exhaustion.

It can be challenging for those looking to increase muscle mass
The ketogenic diet is a popular, low-carb, high-fat eating style that puts your body in a state of ketosis, using fat for energy instead of carbohydrates. While the keto diet can be beneficial for weight loss and boosted energy, it may not be optimal for those looking to increase muscle mass.
Maintaining and growing muscle mass is important for slowing down the ageing process and protecting against age-related bone loss. Additionally, muscle mass helps burn more calories daily, even at rest. While a ketogenic diet can be effective for maintaining muscle mass, maximising muscle growth can be challenging due to several factors.
Firstly, muscle growth requires a sufficient amount of protein to promote muscle synthesis and tissue repair. However, some versions of the ketogenic diet may involve restricting protein intake, making it harder to consume enough protein for muscle growth.
Secondly, the ketogenic diet is often low in calories, which can create a challenge for those looking to increase muscle mass. To maximise muscle growth, it is necessary to consume more calories than you expend throughout the day. This can be difficult on a keto diet, where weight loss is a common goal, and calorie restriction is typical.
Additionally, the ketogenic diet can affect exercise performance, especially for activities requiring short bursts of energy, such as weightlifting or high-intensity interval training (HIIT). The keto diet may impair energy utilisation and speed up exhaustion, making it challenging to perform intense workouts necessary for muscle growth.
While the ketogenic diet may not be ideal for maximising muscle mass, it is possible to make adjustments. For instance, consuming adequate protein, especially after workouts, can boost muscle recovery. Additionally, implementing a targeted ketogenic diet by consuming easily digestible carbs before exercise can improve performance.

It may be beneficial for those looking to maintain muscle mass
The ketogenic diet is a popular, low-carb, high-fat eating style that puts your body in a state of ketosis, using fat for energy instead of carbohydrates. While the ketogenic diet can be a good way to train your body to use fat as a fuel source, it does not mean that the body will use up all the fat.
The keto diet may be beneficial for those looking to maintain muscle mass. Maintaining and growing muscle mass helps slow down the ageing process and protect against the risk of age-related bone loss. Muscle mass helps you burn more calories each day, even when you are not exercising. If you are in the gym to maintain the muscle mass you have, a ketogenic diet could work for you. However, maximising muscle growth may be challenging as muscle growth requires a good amount of protein, which is necessary to promote muscle synthesis and tissue repair. Some versions of the keto diet may involve restricting protein intake.
If you are trying to maintain muscle mass while on a ketogenic diet, it is recommended to eat around 1 gram of protein per pound of lean body mass (2.2 grams of protein per kilogram). If you are trying to lose fat and maintain muscle, the same amount of protein is recommended. However, some may be able to gain muscle with protein intakes above 1.3 grams per pound of lean body mass (3 grams per kilogram).
If you are not an athlete, implementing the ketogenic diet will be less complicated, especially if your primary form of exercise is cardio. Cardio workouts do not require high-intensity training that burns sugar and glycogen. Instead, you only need to get your heart rate up and maintain it. As a result, your health will improve in many ways. Due to the low to moderate intensity of cardio, the ketogenic diet will not impair your cardio exercise performance. In fact, you may be able to work out for longer without getting tired when you are in ketosis.

High-intensity workouts are not recommended while on the keto diet
The ketogenic diet is designed to put the body in a state of ketosis, where it burns fat as fuel instead of carbohydrates. While this can be a good way to train your body to use fat as a fuel source, it doesn't mean that the body will use up all that fat during exercise.
Some research suggests that the keto diet may impair muscle growth and reduce energy levels, especially during high-intensity exercise. One small study from February 2017 found that participants' performance in endurance capacity and peak power dropped after following a ketogenic diet for six weeks. Similarly, a mouse study showed that following a ketogenic diet for eight weeks increased muscle recovery following exhaustive exercise, but the diet ultimately impaired exercise performance in athletes.
However, it's important to note that some people have found success in combining keto with high-intensity interval training (HIIT). In one study, participants restricted carbs to 50 grams daily for four weeks, and the results showed that this adaptation period did not compromise HIIT performance. Additionally, taking creatine on keto can help muscles produce more energy, enhancing HIIT workouts.
While high-intensity workouts may be challenging on a ketogenic diet, low-intensity workouts may be less affected. Some research suggests that the keto diet might speed muscle recovery, boost fat burning, and enhance endurance, making it suitable for endurance athletes.

Frequently asked questions
Exercise is not necessary for the ketogenic diet to be effective, but it can help maximise weight loss results, increase muscle mass, and give you a long-lasting energy boost.
The ketogenic diet trains your body to use fat as a fuel source, so when you exercise, your body will use up that fat. The keto diet is also said to increase endurance during exercise and offer a faster recovery period after intense workouts.
The ketogenic diet can be low in calories and restrict protein intake, which can make it harder to increase muscle mass. It may also lead to decreased performance in endurance capacity and peak power.
Aerobic exercise (low-intensity, steady-state cardio) is recommended for the keto diet as it uses fat as its primary energy source. This includes strength training, yoga, and stability training. High-intensity workouts with repeated hard efforts tend not to go well with the keto diet.
When starting a keto diet, you may experience subpar energy levels. It is recommended to scale back on the intensity of your workouts and gradually increase it once a week to find your body's limits.
