Best Pre-Workout Carb Intake For Keto Dieters

The ketogenic diet is a popular choice for those looking to lose weight, improve their health, and boost athletic performance. But can you work out on a keto diet, and does eating carbs before a workout affect ketosis? The short answer is yes, you can work out on keto, and eating a small number of carbs before a workout can actually enhance your performance.

The Targeted Ketogenic Diet (TKD) is a variation of the standard keto diet that involves consuming carbohydrates around workout times. This approach is designed to improve exercise performance during high-intensity workouts or extended periods of activity. By consuming carbs before or during a workout, individuals can fuel their muscles and improve endurance. The TKD is especially beneficial for athletes or individuals who engage in high-intensity training or endurance exercises.

However, it's important to note that the TKD may not be necessary for everyone. Some individuals may perform well on a standard keto diet, even during high-intensity exercises. Additionally, the TKD may only be beneficial during the initial stages of adopting a keto diet, as the body becomes fat-adapted over time.

When adopting the TKD, it's crucial to choose the right types of carbs and consume them in moderation. Simple, easily digestible carbs such as dextrose, glucose, or high-glycemic foods are recommended. The amount of carbs can vary from 15 to 50 grams, depending on the individual's needs and the intensity of the workout.

In conclusion, the TKD can be a useful strategy for keto dieters who want to enhance their workout performance, especially for high-intensity or endurance exercises. However, it's important to tailor the approach to your specific needs and goals, as everyone's experience with keto may vary.

How many carbs can you eat before a keto workout?

The number of carbohydrates (carbs) you can eat before a keto workout depends on several factors, including the type of workout, your activity level, and your unique carb count.

Types of Keto Diets

There are three main types of keto diets: the Standard Ketogenic Diet (SKD), the Cyclical Ketogenic Diet (CKD), and the Targeted Ketogenic Diet (TKD). The SKD is the traditional keto diet, which involves keeping carbs low at all times. The CKD involves carb loading for one or two days a week, followed by super low-carb intake for the rest of the week. The TKD is a compromise between the SKD and CKD, allowing for increased net carb intake to promote high-intensity exercise performance without staying out of ketosis for long periods.

On a TKD, the general recommendation is to consume 15-50 grams of fast-absorbing carbs before, during, or after a workout. These carbs can come in the form of dextrose powder or real food like white potatoes or white rice. It's important to note that the type of carbs you eat matters – simple sugars like dextrose and glucose are more likely to be burned during exercise or stored as muscle glycogen, while fructose goes directly to the liver for storage and does not improve exercise performance.

Individual Variation

It's worth noting that the number of carbs you can eat before a keto workout may vary from person to person. Some people can eat over 50 grams of carbs and still remain in ketosis, while others may need to stay under 30 grams. It's important to determine your unique carb count by measuring your ketone levels throughout the day using ketone test strips.

Timing of Carb Intake

The timing of carb intake is also crucial. It is recommended to consume carbs 30-60 minutes before a workout, as this will provide a boost of energy and improve performance. Eating carbs before or during a workout may be more beneficial than consuming them afterward, as the extra glucose can help fuel glycolytic exercises and intense exercise will burn the extra glucose, allowing you to return to a ketogenic state more swiftly.

Other Considerations

When following a TKD, it's important to keep your calorie intake constant. If you add carb calories before your workout, subtract fat calories from another meal to maintain a consistent energy intake. Additionally, supplementing with electrolytes and specific supplements like creatine, L-citrulline, and MCT oil can help enhance the effects of the diet and improve exercise performance.

What are the best sources of carbs before a keto workout?

When it comes to fuelling your body for a workout while on a keto diet, it's important to remember that carbohydrates are not off the table entirely. In fact, a targeted ketogenic diet (TKD) is a variation of the standard keto diet that involves supplementing with carbohydrate intake around workout times. This approach is particularly beneficial for those engaging in high-intensity workouts or extended periods of activity. By consuming carbohydrates before and during such exercises, you provide your muscle cells with fast-burning fuel, which can enhance performance and aid in recovery.

So, what are the best sources of carbs to consume before a keto workout? Here are some recommendations:

• Dextrose and glucose are considered the best choices as they are quickly absorbed and utilised by the body. Dextrose tablets or glucose gel packets provide a pure source of glucose without any fructose, making them clean sources of carbs for a TKD.
• Sports drinks like Gatorade and Powerade are good options, but be sure to choose varieties without high-fructose corn syrup.
• Natural maple syrup is a natural source of glucose and can provide a quick energy boost.
• Glucose gels, hard candies, and gummy bears are easily digestible and provide a rapid release of glucose.
• Dairy products like Greek yoghurt and cottage cheese offer a good balance of carbohydrates, healthy fats, and protein. Just be sure to choose plain, unsweetened, and full-fat options to avoid added sugars.
• Berries are a keto-friendly fruit option and provide a natural source of complex carbohydrates and antioxidants. Enjoy a small serving before your workout, paired with yoghurt, nut butter, or cheese for added sustenance.
• If you're looking for a convenient, on-the-go option, keto-specific protein bars, such as Bulletproof Collagen Protein Bars, can be a good choice.
• For a more substantial pre-workout meal, consider an egg white omelette with spinach and feta cheese, or keto cloud bread with half a mashed avocado.
• For a quick and easy snack, a handful of nuts or a nut butter can provide healthy fats and some carbohydrates. Just be mindful of the sugar content and opt for sugar-free varieties if possible.

Remember, the goal of a targeted keto approach is to consume just enough carbohydrates to provide glucose for your workout, enhancing performance and supporting muscle recovery. The recommended amount is typically around 25-50 grams of carbohydrates, consumed 30-60 minutes before your workout.

How does the keto diet affect exercise performance?

The ketogenic diet can have a significant impact on exercise performance, depending on the type of activity and duration. While it may not be the best fuel for high-intensity workouts, keto can have benefits for endurance exercises and overall health. Here's a detailed look at how the keto diet can affect your workouts:

High-Intensity Exercise

The keto diet may not be the best fuel source for high-intensity exercises that require short, intense bursts of energy. This is because carbohydrates are typically the primary fuel source for these types of activities. When you're on a keto diet, your body burns fat for energy instead of carbohydrates. Fat is not as easily burned as carbs, making the process less efficient for high-intensity workouts. As a result, the keto diet can limit performance during these intense training sessions.

Endurance Exercise

On the other hand, the keto diet seems to have some benefits for endurance exercises, such as long-distance running or steady-state cycling. By teaching your body to use fat as an alternative fuel source, keto can improve endurance and increase fat burning during these types of workouts. However, it's important to note that some studies have found that keto may impair performance in endurance athletes, so more research is needed to fully understand the effects.

Muscle Recovery

The keto diet has also been linked to improved muscle recovery after workouts. Some studies have shown that keto can speed up post-workout muscle recovery and reduce inflammation. This can be especially beneficial for athletes who need to recover quickly between training sessions.

Fat Burning

The keto diet has a reputation for boosting fat burning, and this effect extends to exercise performance as well. By forcing your body to rely more on fat for fuel, keto can increase the amount of fat burned during workouts, even at different intensity levels. However, it's worth noting that the high-fat content of the keto diet may be a factor in this increased fat burning.

Muscle Growth

While the keto diet may be suitable for maintaining muscle mass, maximizing muscle growth can be challenging. This is because muscle growth requires adequate protein intake, and some versions of the keto diet may restrict protein to maintain a state of ketosis. Additionally, keto diets are often low in calories, making it harder to consume enough protein for muscle synthesis and repair.

Energy Levels

One of the most notable effects of the keto diet on exercise performance is the potential decrease in energy levels, especially during the initial stages of adaptation. Since carbs are the body's main source of energy, severely restricting them can lead to reduced energy levels, especially for high-intensity exercises. However, over time, energy levels may gradually return to normal as your body becomes more efficient at using fat for fuel.

Recommended Exercises on Keto

Due to the limitations of the keto diet for high-intensity exercises, it's best to focus on low-intensity, steady-state activities. Jogging, cycling, rowing, and yoga are some examples of exercises that pair well with the keto diet. While you can still incorporate high-intensity exercises, you may find them more challenging and may need to adjust your expectations.

What are the benefits of a keto diet?

The keto diet is a high-fat, low-carbohydrate eating plan. It has been linked to several health benefits, including:

• Weight loss: Low-carb diets tend to reduce appetite and calorie intake, leading to weight loss.
• Reduced abdominal fat: Low-carb diets can reduce harmful abdominal fat, which is associated with metabolic dysfunction.
• Lowered triglycerides: Triglycerides are fat molecules that increase the risk of heart disease. Low-carb diets are effective at lowering triglyceride levels.
• Increased 'good' HDL cholesterol: Low-carb diets tend to be high in fat, which increases levels of 'good' HDL cholesterol.
• Reduced blood sugar and insulin levels: Low-carb diets can lower blood sugar and insulin levels, which may treat and reverse type 2 diabetes.
• Lowered blood pressure: Low-carb diets can reduce blood pressure, reducing the risk of heart disease, stroke, and kidney failure.
• Effective against metabolic syndrome: Low-carb diets can treat all five symptoms of metabolic syndrome, a condition that increases the risk of heart disease and type 2 diabetes.
• Improved 'bad' LDL cholesterol levels: Low-carb diets increase the size of 'bad' LDL cholesterol particles, reducing their harmful effects. They may also reduce the number of total LDL particles in the bloodstream.
• Therapeutic for brain disorders: Low-carb diets have been used to treat epilepsy in children and are being studied for their effects on other brain conditions, such as Alzheimer's and Parkinson's disease.

How do you start a keto diet?

Starting a keto diet can be challenging, as it involves a significant shift in your eating habits. Here is a step-by-step guide to help you get started on a keto diet:

• Understand the keto diet: The keto diet, or ketogenic diet, is a high-fat, very low-carb eating plan. It involves drastically reducing your carbohydrate intake and replacing it with healthy fats. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes efficient at burning fat for energy.
• Know your food choices: On a keto diet, you'll be severely limiting carbs to around 20-30 grams per day. Avoid high-carb foods like bread, pasta, chips, cookies, candy, and ice cream. Even fruits, beans, and most vegetables are off the menu. Focus on meat, fish, eggs, nuts, healthy oils, and some low-carb veggies.
• Adjust your fat intake: Keto involves consuming a lot of fat, typically 60-70% of your daily calories. This can be challenging if you're used to a low-fat diet. Start making small adjustments, like cooking with more olive or avocado oil, choosing non-starchy vegetables, and adding more fat to your protein sources.
• Moderate your protein intake: It's a common misconception that you can eat unlimited protein on keto. In reality, you need to keep your protein intake moderate, as excess protein can be converted into glucose and take your body out of ketosis.
• Plan your meals: Look for keto-approved recipes and meal ideas to ensure you're getting a variety of nutritious foods. Having a plan will help you stick to the diet and avoid reaching for high-carb options.
• Prepare for side effects: The "keto flu" is a common side effect when starting the diet. You may experience lethargy, mental fog, constipation, or diarrhea as your body adjusts to burning fat for energy. Choose a slow time to start the diet, and take it easy with exercise for the first week or two.
• Up your electrolytes: In ketosis, your body excretes more water and electrolytes. Make sure to get enough sodium and potassium by salting your food, drinking bone broth, and eating non-starchy veggies like asparagus, kale, and bell peppers.
• Be mindful of restrictions: Keto may not be suitable for everyone. If you have medical conditions such as insulin dependence, high blood sugar, or high blood pressure, consult your doctor before starting. It may also be challenging for vegans or those with existing dietary restrictions.
• Have a long-term plan: Keto is not meant to be a forever diet. It's typically done short-term (3-6 months) and should lead to a healthier overall eating pattern, including more non-starchy vegetables and fewer carbs.
• Decrease carbs gradually: When starting a keto diet, gradually reduce your carb intake over a period of a few weeks. This will help you achieve ketosis and make the transition easier.
• Increase healthy fats: As you reduce carbs, increase your intake of healthy fats like olive oil, avocado oil, coconut oil, cheese, eggs, nuts, and fish. This will help you stay full and ensure you're getting enough calories.
• Maintain your protein intake: Eat enough protein to supply your body with essential amino acids. Aim for 20-30% of your diet to be made up of protein.
• Drink plenty of water: Keto diets have a diuretic effect, so it's important to stay well-hydrated. Drink a minimum of 6-8 glasses of water per day, and more if you're exercising or in hot weather.
• Stay social: You can still dine out and socialise while on a keto diet. Check menus in advance, stick to meat and veggie options, and opt for salads or low-carb sides.

Remember, it's important to consult with a healthcare professional before making any significant dietary changes, especially if you have any health concerns or conditions. They can guide you in determining if the keto diet is right for you and provide personalised advice.
