Keto Protein: What's The Deal?

The ketogenic, or keto, diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. The keto diet is especially useful for losing excess body fat without hunger, and for improving type 2 diabetes or metabolic syndrome. On a keto diet, you cut back significantly on carbohydrates, also known as carbs, in order to burn fat for fuel. This can put your body into a metabolic state called ketosis, in which your liver turns fat into small energy molecules called ketones, which your brain and other organs can use for energy. Eating a keto diet lowers insulin levels, often dramatically, and naturally reduces calorie intake, which can help you access your body fat stores for energy.

Keto and protein intake for bodybuilders

The ketogenic diet is a very low-carb, high-fat diet that is often used for weight loss. It can be challenging to build muscle on a keto diet, as carbohydrates are essential for muscle growth. However, it is not impossible, and bodybuilders can still gain muscle mass while following a keto diet. Here are some tips for bodybuilders who want to maximise their muscle growth while on a keto diet:

Determine Your Calorie Intake

To build muscle effectively, you need to consistently consume more calories than you burn. Calculate your maintenance calories, which is the number of calories you need to consume per day to maintain your current weight. When trying to build muscle, it is recommended to increase your calorie intake by about 15% above your maintenance calories. For example, if your maintenance calories are 2000 per day, you should aim for 2300 calories per day to support muscle growth. It is also important to adjust your calorie intake over time as your weight changes.

Eat Adequate Protein

Protein is crucial for building muscle, as it is the building block of muscles. Most studies suggest consuming 0.7–0.9 grams of protein per pound of body weight (or 1.6–2.0 grams per kg) to optimise muscle growth. On a keto diet, it is important not to consume too much protein, as it can encourage the body to use gluconeogenesis, a process where amino acids from protein are converted into sugar, potentially disrupting ketosis. Therefore, aim for around 1 gram of protein per pound of body weight (2.1 grams per kg) to stay within the recommended range for effective muscle building while maintaining ketosis.

Track Your Carb Intake

To stay in ketosis, it is crucial to restrict your carbohydrate intake. Typically, this means consuming fewer than 50 grams of carbs per day. Timing your carb intake around your workouts can be beneficial, and this strategy is known as a targeted keto diet. If you feel your workout performance is suffering due to low carb intake, consider a targeted keto approach.

Increase Your Fat Intake

When on a keto diet, your body relies primarily on fat for fuel. After accounting for your protein and carb intake, the rest of your daily calorie needs should come from fat. Both protein and carbs provide 4 calories per gram, while fat provides 9 calories per gram. Calculate your daily fat requirements by subtracting your protein and carb needs from your total daily calorie needs and then dividing the remaining number by 9.

Resistance Training

While nutrition is essential, resistance training is equally crucial for gaining muscle. Incorporate resistance training exercises such as weight lifting, squats, bench presses, pull-ups, and push-ups into your weekly routine. Consider working with a personal trainer to ensure proper form and maximise your efforts.

Consider Supplements

Although not necessary, supplements can help you meet your daily protein goals. Protein powder supplements, such as whey, casein, pea, or hemp protein, can assist if you struggle to reach your protein targets. Additionally, consider a creatine monohydrate supplement, as it has been shown to aid in gym performance and lead to increased muscle gain.

Optimise Hormones

Hormones like human growth hormone, cortisol, insulin, testosterone, and IGF-1 play a significant role in regulating muscle and fat mass. Optimise these hormones by focusing on resistance training, adequate nutrition, essential fatty acids, and getting enough sleep. Prioritise stress management through techniques like meditation, as chronic stress can lead to increased cortisol levels, which can hinder muscle growth and promote fat retention.

Stay Hydrated

The ketogenic diet and intense workouts can lead to significant water loss, so it is crucial to drink plenty of water. For women, aim for at least 2.7 litres of water per day, and for men, aim for at least 3.7 litres. Additionally, drink extra water to compensate for water loss during exercise and the initial phase of the ketogenic diet.

Keto and protein intake for the elderly

The keto diet is a low-carb, high-fat, and moderate-protein diet. It involves reducing carbohydrate intake to less than 50 grams per day, which puts the body in a metabolic state called ketosis, where it burns stored fat for energy instead of glucose. This diet has gained popularity due to its potential benefits for weight loss, improved cholesterol levels, reduced blood pressure, and increased energy.

Potential Benefits for the Elderly

The keto diet may be beneficial for older adults in several ways:

• Weight loss: As metabolism slows down with age, losing weight can become more challenging. By reducing carbs, the keto diet promotes weight loss by burning stored fat. This can also lead to reduced joint discomfort and improved mobility.
• Muscle mass preservation: Aging is associated with a loss of muscle mass. The keto diet, being high in protein, promotes muscle protein synthesis and may help prevent the breakdown of muscle mass.
• Blood sugar reduction: Many older adults have prediabetes or type 2 diabetes. The keto diet can improve blood sugar control by reducing carbohydrate intake, leading to lower blood glucose and HbA1c levels.
• Nutrient deficiencies prevention: The keto diet includes nutrient-dense foods like meats, poultry, seafood, eggs, avocados, and green leafy vegetables, which can help prevent micronutrient deficiencies that could lead to cognitive decline.

Potential Risks and Considerations

• Existing medical conditions: The keto diet is not recommended for individuals with a history of eating disorders, heart disease, kidney disease, or pregnancy. It is crucial to consult a healthcare provider before starting the keto diet, especially for those with diabetes, high blood pressure, or liver disease.
• Health and fitness goals: Identify specific goals, such as weight loss or blood sugar management, to track progress.
• Access to keto-friendly foods: Examples of affordable keto-friendly foods include eggs, chicken thighs, and frozen vegetables like broccoli and cauliflower.
• Long-term adherence: Consistency is key. There are different variations of the keto diet, such as the standard keto diet, cyclical keto diet, pescatarian keto, and vegetarian keto.
• Tracking progress: Use tools like a blood ketone meter or urine strips to monitor ketosis, and regularly check health markers for improvements.

Tips for Success

• Know your keto macros: Use a keto calculator to determine your daily carb, fat, and protein intake to reach and maintain ketosis.
• Get enough electrolytes: Prevent dehydration by consuming keto-friendly electrolyte drinks, especially during the initial transition to the keto diet.
• Choose keto-friendly foods: Opt for animal-based foods, non-starchy vegetables, and low-carb fruits like leafy greens, berries, and avocados.
• Incorporate physical activity: Engage in cardiovascular exercises like brisk walking and strength training exercises like squats to improve endurance and boost muscle mass and stability.
• Have keto-friendly snacks: Snacking ensures adequate nutrient intake. Good low-carb options include boiled eggs, cheddar cheese slices, almonds, and cashews.

Even for older adults, adopting a keto diet can be a worthwhile goal. However, it is essential to consult with healthcare professionals and make informed, balanced decisions about dietary changes, ensuring that the benefits outweigh the potential risks.

Keto and protein intake for athletes

The ketogenic diet is a popular choice for many athletes, especially those involved in endurance sports. It involves a high-fat, moderate-protein, and low-carbohydrate intake. While it can be effective for some, it's important to understand the potential benefits and drawbacks, especially regarding protein consumption.

The Role of Protein in Keto for Athletes

Protein is essential for athletes on or off a keto diet, as it provides the amino acids required for muscle repair, growth, and overall body function. A moderate protein intake is crucial in a ketogenic diet, and the recommended range is around 20-25% of calories from protein.

Reasons for Moderate Protein Intake in Keto:

• Too Little Protein: Insufficient protein intake can lead to muscle wasting and weight loss. It can also negatively impact the thyroid and cause skin, nail, and hair problems.
• Moderate Protein Supports Ketosis: Moderate protein intake allows circulating ketones to reach optimal levels for ketosis.
• Too Much Protein: Excess protein intake can lead to protein deamination, where the body expels excess amino acids as ammonia, disrupting the ketogenic state as the body uses protein as fuel instead of fat.

Keto and Athletic Performance

The impact of a ketogenic diet on athletic performance is mixed. While some athletes, especially endurance athletes, report improved performance and health, others, particularly those involved in high-intensity, short-duration sports, may experience a drop in performance.

Benefits of Keto for Athletes:

• Endurance: Keto diets can enhance endurance by increasing fat oxidation and improving glycogen storage. This is especially beneficial for long-duration, moderate-intensity exercises.
• Weight Loss: Keto can aid in weight loss, which may improve athletic performance, particularly in sports with weight classes or where a lower body weight is advantageous.
• Health: Keto diets have been linked to reduced body fat, improved metabolic health, and reduced inflammation, which may positively impact overall athletic performance and well-being.

Drawbacks of Keto for Athletes:

• High-Intensity Exercise: Keto diets may impair performance in high-intensity, anaerobic exercises due to reduced muscle glycogen stores. This can affect sprinting and power-based sports.
• Adaptation Period: Adapting to a keto diet can take several months, during which athletic performance may be negatively impacted.
• Individual Variability: The effects of keto on athletic performance vary greatly between individuals, with some experiencing improved performance while others see a decline.

The ketogenic diet can be a viable option for athletes, especially endurance athletes, seeking improved performance and health. However, it is essential to maintain a moderate protein intake to support ketosis and avoid potential drawbacks. The decision to adopt a keto diet should be made with a comprehensive understanding of its potential benefits and drawbacks and, ideally, under the guidance of a trained professional.

Keto and protein intake for vegetarians and vegans

The ketogenic, or keto, diet is a high-fat, low-carb diet that has become increasingly popular in recent years. Although it usually contains animal products, it is possible to adapt it to fit a vegetarian or vegan diet.

Vegetarian keto

Vegetarian keto is a high-fat, low-carb eating pattern that eliminates meat and fish. It relies on other healthy fats, such as coconut oil, eggs, avocados, nuts, and seeds.

The main challenge of a vegetarian keto diet is that many vegetarian staples, such as beans, lentils, and whole grains, are high in carbs. Vegetarians also need to be mindful of getting enough key nutrients, such as vitamins B12 and D, iron, zinc, calcium, omega-3s, and protein.

Some good sources of protein for a vegetarian keto diet include:

• Eggs
• Dairy products (yogurt, cottage cheese, hard and semi-hard cheeses)
• Soy products (tofu, edamame, tempeh, natto)
• Nuts and seeds (hemp seeds, peanuts or almonds, pecans, macadamias)

Vegan keto

The vegan keto diet is a low-carb, high-fat, moderate-protein diet that excludes all animal-based foods. This means that, in addition to meat, fish, and dairy, vegans following a keto diet also need to avoid eggs and other animal products such as honey.

Because the vegan keto diet is so restrictive, it can be challenging to get enough protein and other important nutrients. It is important for those following this diet to supplement with high-quality vitamins and minerals and carefully plan their meals to ensure they are getting enough of the right foods.

Some good sources of protein for a vegan keto diet include:

• Vegan protein sources (tofu, tempeh, spirulina, natto, nutritional yeast)
• Nuts and seeds (almonds, walnuts, cashews, macadamias, pistachios, Brazil nuts, hemp seeds, chia seeds, pumpkin seeds)
• Nut and seed butters (almond butter, peanut butter, sunflower butter, cashew butter)
• Vegan full-fat "dairy" (coconut yogurt, vegan butter, cashew cheese, vegan cream cheese)

Keto and protein intake for weight loss

The keto diet is a low-carb, high-fat diet that has become increasingly popular for its potential benefits for weight loss and blood sugar control. While the standard keto diet involves getting 75% of your calories from fat, 20% from protein, and 5% from carbs, there are several variations of the keto diet that have emerged to meet different needs and goals. Here's a closer look at the role of protein in the keto diet and how it can impact weight loss:

The Importance of Protein on Keto

Protein is an essential macronutrient, needed for various bodily processes, including muscle growth and repair, supporting healthy bones and joints, promoting healthy skin, hair, and nails, maintaining the pH of blood and bodily fluids, and supporting immune function. On the keto diet, it's crucial to ensure you're getting enough protein, as consuming too little can have negative consequences.

Calculating Protein Intake on Keto

To determine how much protein you should be eating on a ketogenic diet, it's recommended to calculate your protein intake based on your body weight and activity level. As a general guideline, aim for 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.

The Myth of Too Much Protein on Keto

There is a common fear that consuming too much protein on a ketogenic diet may lead to increased glucose production through a process called gluconeogenesis (GNG) and knock you out of ketosis. However, this belief is largely a myth. GNG is a natural and essential process that occurs regardless of your protein intake, and studies suggest that extra protein does not lead to an increase in GNG production. While the body does require small amounts of glucose for certain functions, this can be obtained through adequate protein intake on keto without kicking you out of ketosis.

Protein Intake for Weight Loss on Keto

When it comes to weight loss on the keto diet, protein intake plays a crucial role. Research suggests that diets containing 18%-25% protein can result in greater muscle maintenance compared to lower protein diets. Additionally, a moderate to high protein intake of 1.2-3.0 grams of protein per kilogram of body weight has been shown to prevent muscle loss and even increase muscle mass when combined with calorie restriction and resistance training. For those aiming for weight loss on keto, a higher protein intake of 2.4 to 3.0 grams of protein per kilogram of body weight may be beneficial, especially when coupled with resistance training.

Keto-Friendly Protein Sources

When it comes to choosing protein sources on the keto diet, it's important to prioritize healthy options. Animal proteins such as meat, poultry, seafood, eggs, and dairy are excellent choices, as they are low in carbs and high in fat. Plant-based proteins like tofu, soy-based products, nuts, and seeds can also be included, but some are higher in carbs than others. It's best to avoid overly processed meats, as they have been linked to an increased risk of heart disease and other health issues.

In conclusion, protein intake is a crucial aspect of the keto diet, and getting enough protein is essential for weight loss and overall health. By understanding the role of protein in the keto diet and calculating your individual protein needs, you can optimize your results and reap the benefits of this popular dietary approach.
