Protein Consumption On Keto: How Much Is Too Much?

The ketogenic, or keto, diet is a high-fat, low-carb, moderate-protein diet. Typically, the keto diet includes restricting your carb intake to just 5% to 10% of your calories, with fat intake increasing to 55% to 60% of your calories, and the remaining 30% to 35% of your calories coming from protein. However, there are several variations of the keto diet, including the standard keto diet, the high-protein keto diet, and the cyclical keto diet, which have different macro ratios.

The standard keto diet is the most common approach, with 75% of calories from fat, 20% from protein, and 5% from carbs. The high-protein keto diet involves getting 35% of your calories from protein, 60% from fat, and just 5% from carbs. The cyclical keto diet involves cycling in and out of ketosis, usually with five keto days followed by one or two off days with more carbs.

While the keto diet is popular for weight loss, there are concerns about its restrictiveness and long-term health effects. Some people may also find that they need to tweak the diet to meet their needs, such as increasing their protein intake to protect muscle mass.

The standard keto diet is the most common version

The standard keto diet is the most common approach to keto, and it involves getting 75 percent of your calories from fat, 20 percent from protein, and 5 percent from carbs. That means limiting your daily carb intake to about 20 to 30 grams of carbs. It's important to note that while this is the keto diet that most people follow, it's not the original version, which was created to help treat epilepsy.

The standard keto diet is stricter than other variations, such as the targeted keto diet, cyclical keto diet, and high-protein keto diet. These alternative versions allow for more carbs and/or protein, making them more suitable for certain individuals such as athletes or bodybuilders.

The standard keto diet is a popular approach for those looking to accelerate their weight loss and tap into the other reported health benefits of keto. However, it's not suitable for everyone, and some people may find it challenging to follow due to its restrictiveness.

• Fat intake: To achieve the recommended 75 percent of calories from fat, individuals may need to increase their consumption of healthy fats such as fatty fish, olive oil, nuts, and seeds.
• Carb intake: Limiting carbs to 20-30 grams per day can be challenging and may require careful planning and tracking.
• Protein intake: Meeting the protein requirement of 20 percent without exceeding it can be tricky, especially for those who are very active or have a high muscle mass.
• Health considerations: The standard keto diet may not be suitable for pregnant women, people with diabetes, or those with a history of kidney stones. Additionally, it can cause side effects such as bad breath, dizziness, constipation, and low energy levels, commonly known as "keto flu."

High-protein keto may be best for bodybuilders

The ketogenic diet is often associated with fat loss, mental clarity, and health, but building muscle is not usually one of them. However, there is merit to and research supporting the goal of building muscle on keto. Many bodybuilders have followed something close to a ketogenic diet as part of their show prep for decades.

If bodybuilding is your goal, you will first need to modify your "the more protein, the better" mindset. While getting adequate protein is crucial when building and maintaining muscle mass, that doesn't mean eating more protein will always lead to more muscle growth, especially on a ketogenic diet. When you're on a keto diet, eating excessive amounts of protein can kick you out of ketosis.

Ketogenic Diet Protein Percentage

The ketogenic diet is usually considered a moderate protein diet, not a high-protein diet. An effective ketogenic diet should include 15-20% of total calories from protein, and no more. This is quite low compared to the 30-40% of calories from protein recommended by most online nutrition calculators in the bodybuilding community when you set your goal as "muscle growth."

However, a study published in the Journal of Sports Sciences found that consuming 0.6-0.8 grams of protein (evenly distributed between 3-4 meals while also in a calorie surplus) was adequate to optimize levels of muscle protein synthesis. This means that devoting 15-20% of your calories to protein is still enough to get you to the threshold for muscle growth.

High-Protein Ketogenic Diet

The high-protein ketogenic diet consists of 60% fat, 35% protein, and 5% carbohydrates. The higher protein content may be effective for athletes and those who are obese. However, if you eat too much protein, your body will convert it into glucose through a process known as gluconeogenesis, which can kick you out of ketosis.

Protein Requirements for Bodybuilders

Bodybuilders will generally require more protein than the average person. Although the average person requires just 0.8 grams of protein per kilogram of body weight, researchers have found that doubling that to 1.6 grams of protein per kilogram of weight can help optimize muscle growth. And if you’re a competitive bodybuilder, up to 2.2 grams of protein per kilogram of body weight is recommended.

Keto Bodybuilding Challenges

Some of the most common keto bodybuilding challenges are not eating enough protein, not eating enough calories, and inconsistent nutrition. It can be challenging to eat enough on keto since the low-carb, high-fat diet is so filling. However, as long as you’re hitting your protein goal, you can add additional fat to get your calories up to where they need to be.

Building Muscle on Keto

To build muscle on keto, you need to eat enough protein and calories, do intense workouts with progressive overload, prioritize rest and recovery with sleep, low stress, and good nutrition, and be mindful of your hydration and electrolyte status.

Cyclical keto can help you stick to the diet

The ketogenic diet is a high-fat, low-carb diet that can be challenging to stick to, especially for beginners. This is where cyclical keto comes in.

Cyclical keto, also known as keto cycling, involves following a standard ketogenic diet for a certain amount of time and then taking a day or two off. This typically means having five or six days on keto followed by one or two days of higher-carb intake.

Knowing that there's a day in the near future when you'll be allowed to eat carbs again might help you stick to the diet for longer. Cyclical keto can be beneficial for those who crave higher-carb items from time to time. It can also be a good strategy for breaking through a weight loss plateau.

How to Do it Right

It's important to note that cyclical keto is not recommended for beginners. It's best to do a standard ketogenic diet for at least a month before attempting cyclical keto to allow your body to reach a fat-adapted state. During this period, your body will be able to go in and out of ketosis easily, which means it's metabolically flexible.

When doing cyclical keto, it's crucial to choose healthy, complex carbs on your higher-carb days, such as whole-wheat pasta, brown rice, sweet potatoes, and whole grains. This will make it easier for your body to re-adapt to ketosis.

Potential Downsides

There is limited research on the cyclical keto diet, so the potential downsides are largely unknown. However, some people may experience water retention, tiredness, brain fog, and unhealthy food cravings as a result of increased carbs. It's also important to note that cyclical keto might not be suitable for those with diabetes or sensitive to carbohydrates.

In Conclusion

Cyclical keto can be a helpful strategy for sticking to the ketogenic diet, but it's not for everyone. It's important to do your research, consult with a healthcare professional, and make sure your body is fat-adapted before attempting this approach.

Strict keto is used for epilepsy treatment

The ketogenic diet is a special high-fat, low-carbohydrate diet that helps control seizures in some people with epilepsy. It is usually used in children with seizures that do not respond to medications. The diet is stricter than the modified Atkins diet, requiring careful measurements of calories, fluids, and proteins. The name "ketogenic" means that it produces ketones in the body. Ketones are formed when the body uses fat for energy instead of carbohydrates. The diet is carefully monitored by a dietitian and a neurologist.

The classic ketogenic diet, or CKD, is rich in lipids (90%) and low in carbohydrates and protein. It is a rigid diet, mathematically and individually calculated, and medically monitored. The goal is to reach a ratio of four parts fat to one part protein and carbohydrates, described as "4:1." The modified Atkins diet, or MAD, aims to provide increased flexibility and palatability, with a 1:1 ratio of fat to carbohydrates and protein, and contains around 65% fat, 25% protein, and 10% carbohydrates. The low glycemic index diet, or LGIT, is based on a ratio of 0.6:1 of fat to carbohydrates and protein, containing 60% fat, 30% protein, and 10% carbohydrates.

The ketogenic diet has been shown to be effective in reducing seizures in children with epilepsy. Over half of the children who go on the diet have at least a 50% reduction in the number of their seizures, and some children, usually 10-15%, become seizure-free. The diet has also been used in other neurological conditions, such as Alzheimer's disease and autism spectrum disorder.

The ketogenic diet is not without risks. Side effects occurring with long-term diet use include low bone density and bone fractures, slower growth than typical, and sluggishness or tiredness. It is important to note that the ketogenic diet should be closely monitored by healthcare providers, and one should not attempt the diet on their own.

Keto 2.0 is a lower-fat type of the standard diet

Keto 2.0: A Lower-Fat, Less-Restrictive Version of the Standard Keto Diet

Keto 2.0 is a less strict version of the traditional keto diet, designed to be more sustainable and healthier in the long term. While there are no formal published guidelines for keto 2.0, it is generally understood to consist of 50% fat, 30% protein, and 20% carbohydrates. This is in contrast to the standard keto diet, which is typically 90% fat, 8% protein, and 2% carbohydrates, with some variations suggesting 70-80% fat, 10-20% protein, and 5-10% carbohydrates.

How Does Keto 2.0 Differ from the Standard Keto Diet?

Allows for More Carbohydrates

Keto 2.0 allows for a higher intake of carbohydrates, permitting around 100 grams of carbohydrates per 2,000 total daily calories. This enables followers of the diet to consume more health-protective fruits, vegetables, whole grains, and legumes, which are rich in dietary fiber, vitamins, and minerals.

Emphasizes Food Choices

The higher carbohydrate limit of keto 2.0 means that followers can more closely align their diet with the Mediterranean diet, which includes staples such as fruits, vegetables, whole grains, and legumes. In contrast, the traditional keto diet is highly restrictive of these food groups, making it difficult to consume the suggested daily intake of these nutrient-dense foods.

Less Research Available

The traditional keto diet has been the subject of numerous studies investigating its effectiveness in treating various health conditions, such as type 2 diabetes, cancer, and obesity. On the other hand, keto 2.0 has not been formally studied, so there is limited evidence to support recommending the diet for specific health conditions.

Benefits of Keto 2.0

Although keto 2.0 has not been extensively researched, it may offer several potential benefits, particularly for those transitioning from a diet high in ultra-processed foods, refined carbohydrates, added sugars, and salt.

Improved General Physical Health

Keto 2.0 may lead to improved health for those who previously consumed a lot of ultra-processed and refined foods. By design, the diet makes it difficult to include many of these less nutritious options.

Higher Intake of Essential Fatty Acids

The higher-fat content of keto 2.0 can include primarily plant-based oils, nuts, seeds, and fatty fish, which are rich sources of essential fatty acids like omega-3s. These fatty acids are known to provide protective effects for the heart, brain, and eyes.

Risks and Side Effects of Keto 2.0

The potential risks and side effects of keto 2.0 are not yet fully understood due to a lack of research on the specific macronutrient breakdown of this diet. However, some possible risks may include:

Impact on Cholesterol Levels

If keto 2.0 includes a high amount of saturated fat-rich animal products, such as red and processed meat, butter, and heavy cream, it may lead to an increase in cholesterol levels, which is a risk factor for heart disease.

Nutrient Deficiencies and Constipation

The lower intake of nutrient-dense plant foods on keto 2.0 may lead to vitamin and mineral deficiencies. Additionally, the lower fiber content of the diet may result in constipation.

Keto 2.0 is a less restrictive version of the standard keto diet, allowing for more carbohydrates and emphasizing healthier protein and fat sources. While it may offer some potential benefits, particularly for those transitioning from a less nutritious diet, it has not been extensively studied, so its long-term effectiveness and safety are not yet established. As with any diet, it is important to consult a registered dietitian or healthcare provider to determine if keto 2.0 is suitable for your individual needs and goals.
