Moderating Protein Intake For Optimal Ketosis

The ketogenic diet is a low-carb, high-fat diet that has gained popularity for its ability to induce weight loss and improve health. While the standard ketogenic diet recommends a breakdown of 70% fat, 20% protein, and 10% carbs, there are several variations of the keto diet, including the cyclical keto diet, high-protein keto diet, and more.

Protein is a crucial component of the keto diet, as it is one of the three macronutrients and plays an essential role in the body. It is a building block for muscles, skin, bone, and hair health, and it helps to prevent muscle loss and promote muscle growth when coupled with resistance training.

However, there is a common misconception that too much protein can kick someone out of ketosis. This belief stems from the idea that excess protein can be converted into glucose through a process called gluconeogenesis, which would reduce ketone levels. Nevertheless, this claim has been disproven, and gluconeogenesis is, in fact, a necessary process for survival and making ketosis possible.

Therefore, it is crucial to consume adequate amounts of protein on the keto diet, and there is no need to fear gluconeogenesis. Eating too little protein can have adverse effects, including worsened workout performance, neuron atrophy, and a weaker immune system.

To calculate the right amount of protein for your keto diet, it is recommended to first determine your protein intake based on your activity level and lean body mass. Then, reduce your carbohydrate intake and get the remaining calories from healthy fats. By following these steps, you can ensure you are consuming enough protein to support your health and fitness goals while still maintaining ketosis.

The Standard Ketogenic Diet (SKD)

The SKD is a very low-carb, moderate-protein, and high-fat diet. It is what most people think of when the keto diet is mentioned and is effective for losing fat quickly when coupled with low to moderate-intensity activities such as walking, cycling, yoga, and light weightlifting.

On the SKD, your primary sources of carbohydrates will be low-carb vegetables, nuts, seeds, and high-fat dairy products. It is important to avoid fruits, starches, added sugars, and other foods that are high in net carbs.

The SKD is not suitable for everyone. Pregnant women, people with diabetes, and those with a history of kidney stones should avoid this diet. Additionally, those with kidney issues or chronic kidney disease should be cautious when increasing their protein intake.

When starting the SKD, you may experience some side effects in the first week, known as the "keto flu." These include fatigue, brain fog, headaches, and gastrointestinal issues. However, by drinking more water, consuming extra electrolytes, and supplementing with ketogenic MCT oil, you can usually remedy these symptoms.

• Calculate your caloric needs and adjust based on your goals.
• Set protein levels according to your goals, usually between 0.8 to 1 gram of protein per pound of lean body mass.
• Set carbohydrate levels to around 20-30 grams of net carbs per day to promote nutritional ketosis.
• Set fat intake levels based on your remaining calorie allowance, focusing on consuming healthy fats from low-carb whole foods.

High-Protein Ketogenic Diet

A High-Protein Ketogenic Diet (HPKD) is similar to the standard keto diet in terms of fat intake, but it involves eating a higher percentage of protein. The standard ketogenic diet (SKD) typically consists of 75% fat, 15-20% protein, and 5-10% carbs. In contrast, the HPKD usually consists of 60-65% fat, 30% protein, and 5-10% carbs.

On the HPKD, the daily fat intake decreases while protein increases. This means eating around 120 grams of protein per day, or about four palm-sized servings. The types of food consumed on the HPKD are the same as on the SKD: healthy fats, quality protein, and non-starchy vegetables.

The main benefit of the HPKD is that it is easier to implement than the SKD. The SKD can be intimidating for beginners as it requires consuming a lot of fat (around 150 grams) every day. The HPKD allows for a higher protein intake, which some may find easier.

However, there is a drawback to the HPKD. Excess protein in the body is converted to glucose and used as fuel, which can hinder the body's ability to enter and remain in ketosis—the state where the body burns ketones, created by the liver from stored fat, as fuel instead of glucose.

Whether the HPKD is easier or harder than the SKD depends on the individual. Some men may prefer the HPKD as they are wired to eat more protein and find it challenging to reduce their intake. Even if someone does not always remain in ketosis with the HPKD, they will still reap the benefits of removing sugar and processed carbs from their diet, including weight loss, increased energy, fewer cravings, and better sleep.

Cyclical Ketogenic Diet (CKD)

The Cyclical Ketogenic Diet (CKD) is a variation of the standard keto diet, which involves going in and out of ketosis on a weekly basis. On a CKD, you eat a very low-carb, high-fat diet for 5-6 days a week, and then have 1-2 days of high-carb intake. During the low-carb days, you limit your carb intake to 50 grams or less, and obtain these carbs from keto-friendly foods such as spinach, broccoli, and nuts. On the high-carb days, you can consume 300-400 grams of carbs, depending on your activity level.

The CKD is popular among athletes as it is believed to enhance exercise performance and improve athletic performance. The extra carbs can be beneficial for longer, more intense workouts that require short bursts of energy, such as HIIT, sprinting, and agility training. The CKD may also aid in weight management, as it can help regulate weight in the long run by increasing leptin, the hormone that promotes satiety and weight regulation.

In addition, the CKD makes it easier to stick to the keto diet as it allows for occasional carb intake, which can boost morale and help with long-term adherence. However, it is important to note that the CKD is not suitable for everyone, especially those with certain medical conditions such as diabetes. It is recommended to consult with a healthcare professional before starting any new diet.

Targeted Ketogenic Diet (TKD)

The Targeted Ketogenic Diet (TKD) is a standard keto diet with added carbohydrates around workout times. It is meant for athletes or those engaging in high-intensity workouts or extended periods of activity. TKD helps improve exercise performance and aids recovery.

The TKD is a "compromise" between the Standard Ketogenic Diet (SKD) and the Cyclical Ketogenic Diet (CKD). It allows for a higher intake of net carbs to promote high-intensity exercise performance, without being out of nutritional ketosis for long periods.

The TKD works by providing muscle cells with fast-burning fuel for maximum effort activities lasting between 10 seconds and 2 minutes. Carbohydrates are essential for such activities as, after around 10 seconds of near-maximal effort, muscles start relying on glucose for energy, using a metabolic pathway called glycolysis.

The recommended amount of carbohydrates to be consumed 30 minutes prior to exercise is 25-50g, in the form of liquids or high-glycemic foods that absorb fast into the body, such as sweet tarts, white bread, or candy bars. However, the best sources of carbs for a successful TKD would be dextrose and glucose, as they avoid fructose, which goes directly to the liver to replenish liver glycogen.

The TKD is especially useful for those who are new to keto and are experiencing a decrease in performance. It can help improve performance and reduce the perceived exertion of runners without impairing ketosis. It can also have an anabolic effect, preventing muscle breakdown and promoting increases in lean muscle mass.

However, it is important to note that the TKD may not be beneficial for those who have been on the keto diet for 1-2 months and are already keto-adapted, as the body can replenish its own glycogen stores without the need for additional dietary carbs.

• Set up your keto macros and carb intake: Calculate your macros, taking into account the extra calories from carb intake, and adjust your fats accordingly.
• Pre-exercise timing and best carbohydrate sources: Consume carbs 30-60 minutes prior to your workout, with a recommended amount of 25g of carbohydrates. For high-intensity sessions lasting over an hour, this amount can be increased to up to 50g. The best sources are glucose gels, hard candies, gummy bears, sugary sports drinks, natural maple syrup/sugar, and dextrose supplements.
• Optimal post-exercise nutrition: Instead of ingesting carbs post-workout, opt for a high-quality protein shake to boost recovery and lean muscle growth.

In conclusion, the Targeted Ketogenic Diet (TKD) is a great option for those engaging in high-intensity workouts who want to improve their performance and aid their recovery. By adding a moderate amount of carbohydrates around workout times, the TKD offers a "compromise" between the SKD and the CKD, allowing for improved exercise performance while still maintaining ketosis.

Protein and Weight Loss

Protein is an essential part of the keto diet, but it's important to get the right amount. Too much protein can kick you out of ketosis, but too little can be dangerous for your health. Here's what you need to know about protein and weight loss on the keto diet.

The amount of protein you need on the keto diet depends on your body and your goals. As a general guideline, it's recommended to consume between 1.2 to 2.0 grams of protein per kilogram of reference body weight. This range has been shown to preserve muscle mass, improve body composition, and provide other health benefits.

If you're trying to lose weight, you may want to aim for the higher end of this range, as protein can help you feel fuller for longer and reduce overeating. It's also important to make sure you're getting enough protein to support muscle growth and repair, especially if you're physically active.

The Benefits of Protein for Weight Loss

Protein has several benefits that can support weight loss:

• It increases feelings of fullness and reduces appetite, which can help you eat less and stick to a calorie deficit.
• It has a high thermic effect, meaning your body burns more calories digesting protein compared to carbs or fat.
• It helps preserve and build muscle mass, which is important for a healthy metabolism and overall health.
• It can help regulate blood sugar levels and reduce fat storage in the liver.

Sources of Protein on Keto

When it comes to choosing protein sources on the keto diet, opt for high-quality, nutrient-dense options. Animal proteins such as meat, poultry, seafood, eggs, and dairy are excellent choices as they provide all the essential amino acids. Plant-based proteins like tofu, soy products, nuts, and seeds can also be included, but be mindful of their carb content.

Common Misconceptions About Protein and Keto

There is a common misconception that too much protein will kick you out of ketosis. While it's true that excess protein can be converted into glucose through gluconeogenesis, this process is highly regulated and stable. Eating more protein will not significantly increase gluconeogenesis or kick you out of ketosis.

However, it's important to note that very high protein intakes can have a moderate insulin-stimulating effect and drive down ketone levels. Therefore, it's best to aim for a moderate protein intake while on the keto diet.

Protein plays a crucial role in the keto diet and is essential for weight loss and overall health. By consuming adequate amounts of high-quality protein, you can support muscle growth and repair, regulate blood sugar, and increase feelings of fullness. Remember to combine your protein intake with a calorie deficit and physical activity for optimal weight loss results on the keto diet.
