Protein On Keto: How Much Is Enough?

The ketogenic or keto diet is a popular eating regimen for those looking to lose fat, build muscle or improve overall health. It involves a metabolic state called ketosis, where the body uses fat for fuel, which is then converted into ketones. The keto diet is typically high in fat, low in carbohydrates, and moderate in protein.

When following the keto diet, it is important to understand how much protein to consume to maintain ketosis. A good breakdown of macronutrient intake includes 70-80% of daily calories from fats, 5-10% from carbohydrates, and 10-20% from proteins.

The amount of protein required on a keto diet depends on individual needs and goals. Generally, a daily protein intake of 1.2 to 2.0 grams per kilogram of body weight is recommended for most people. However, those with certain health conditions or specific goals may require higher or lower protein intake.

It is important to note that the keto diet has some potential downsides and side effects, such as fatigue, lethargy, and cravings for carbohydrate-rich foods. Additionally, the high-fat content of the keto diet may have negative health consequences in the long term. As such, it is important to consult with a healthcare professional before starting any new diet, including the keto diet.

Keto is a high-fat, moderate-protein diet

The keto diet is a very low-carbohydrate, high-fat, and moderate-protein diet. The diet centres on the idea of reaching a metabolic state called "ketosis", where the body is said to increase its efficiency at burning fat for energy.

When on the keto diet, 70-80% of your daily calories should come from fats, ideally from healthy sources like nuts and avocados. Meanwhile, 5-10% of your daily calories should come from carbohydrates. This can be sourced from starchy vegetables like corn or squash. Finally, 10-20% of your daily calories should come from protein.

Keto-friendly sources of animal protein include meat, poultry, seafood, eggs, and cheese. Meanwhile, keto-friendly plant protein sources include tofu, nuts, seeds, and soy-based products.

It is important to note that the keto diet is not a high-protein diet. This is because maintaining the state of ketosis depends on depriving the body of carbohydrates. Since carbohydrates are important for human functioning, this requires sufficient levels of fats and protein to offset the energy imbalance.

The ideal amount of protein intake depends on several factors, including age, weight, and level of physical activity. For example, older adults may require a higher protein intake to maintain muscle mass and physical function. Similarly, those who engage in resistance training and endurance-type exercise likely need more protein than sedentary individuals of the same height and weight.

In general, a daily protein intake of 1.2 to 2.0 grams per kilogram of body weight is recommended for most people. However, this amount can vary depending on individual needs and goals. For instance, those looking to build muscle mass may require a higher protein intake, while those following the keto diet for therapeutic purposes may need to aim for a lower protein intake.

It is worth noting that there are some downsides and negative side effects associated with the keto diet. Restricting carbohydrates for a long period can lead to feelings of tiredness and lethargy, as well as cravings for carbohydrate-rich foods. Additionally, a high-fat diet can have negative health consequences, such as high blood pressure, high cholesterol, and an increased risk of heart disease and stroke.

Therefore, it is important to consult with a registered dietitian or medical expert to determine the appropriate amount of protein intake for your specific needs and goals when following the keto diet.

10-20% of calories should come from protein sources

10-20% of Calories from Protein on Keto

When following a keto diet, it is important to understand how much protein you should consume to keep your body in a ketogenic state. The keto diet is a very low-carbohydrate, high-fat, and moderate-protein diet. Typically, 70-80% of daily calories come from fats, 5-10% from carbohydrates, and 10-20% from proteins.

Keto is not a high-protein diet, and tracking protein intake is crucial because maintaining ketosis depends on depriving the body of carbohydrates. Since carbs are essential for human functioning, sufficient levels of fats and proteins are needed to offset the energy imbalance.

The recommended daily protein intake is around 1.2 to 1.7 grams per kilogram of body weight for most individuals. Consuming protein within this range helps prevent muscle loss, promotes muscle growth (especially with resistance training), and offers other health benefits.

For those looking to build muscle mass or lose fat, it is recommended to aim for between 10% and 20% of calories from protein sources, preferably whole foods or quality supplements. This equates to about 20-30 grams of protein per meal, spread over two or three meals per day.

Best Sources of Protein on Keto

Keto-friendly sources of animal protein include meat, poultry, fatty fish, cheese, and eggs. Plant-based protein sources include tofu, nuts, seeds, and soy-based products.

Expert Opinions on Protein Intake

Nutrition experts have differing opinions on the optimal amount of protein on keto. Dr. Ron Rosedale recommends 1 gram of protein per kilogram of lean muscle mass to promote longevity. In contrast, Dr. Ted Naiman suggests a higher protein intake, especially for weight loss, recommending 1 gram of protein per pound of lean mass. Other experts, like Drs. Steve Phinney and Jeff Volek, recommend 1.5-1.75 grams of protein per kilogram of "ideal" body weight.

Protein and Blood Sugar

One argument for protein restriction is that higher protein intake may increase blood sugar and insulin levels. However, studies have shown that a diet with 30% of calories from protein improved blood glucose control, and protein-rich diets are not known to cause chronically high insulin levels.

While there is no one-size-fits-all approach to keto, aiming for 10-20% of calories from protein sources is a good guideline. This will help ensure you get enough protein to support muscle growth and repair, maintain healthy organs, and promote various other bodily functions. Remember to include a variety of high-quality protein sources in your diet and consider consulting a registered dietitian to fine-tune your protein intake based on your individual needs and goals.

Too much protein can prevent ketosis

The ketogenic or "keto" diet is a very low-carbohydrate, high-fat, and moderate-protein diet. The primary focus of keto is to restrict carbohydrates and eat plenty of fat, but protein intake also plays a crucial role in its success.

How Your Body Responds to Protein Intake

When protein is digested, it triggers the release of insulin and glucagon, two energy-regulating hormones with opposing functions. Insulin stimulates the uptake of sugar into cells and reduces the breakdown and release of fat from fat cells, while glucagon triggers glycogen breakdown, the release of fat from fat cells, and fat burning. For keto dieters, the most striking effect of these hormones is that they have opposing influences on ketone production: insulin decreases it, while glucagon stimulates it.

The ratio of insulin to glucagon released in response to protein intake depends on various factors, including a person's health, diet, gender, and activity levels. Studies indicate that people with type 2 diabetes are much more likely to experience a significant increase in insulin levels after protein intake, which may impair their ketone production or prevent their bodies from entering ketosis. On the other hand, healthier and more active individuals can consume much more protein without it affecting their ketone levels.

How Too Much Protein Becomes a Problem

Protein consumption will typically cause both insulin and glucagon to increase. As a result, insulin levels may rise to the point that you are "kicked out" of ketosis. This is more likely to happen to people with type 2 diabetes or insulin resistance. Conversely, healthier and more active individuals will be able to consume more protein without it affecting their ketone levels.

The ideal protein consumption on keto varies from person to person and depends on factors such as genetics, gender, current macronutrient and calorie intake, insulin sensitivity, activity levels, and body composition.

As a general guideline, it is recommended that sedentary individuals consume 0.6-0.8 grams of protein per pound of lean body mass, regularly active people consume 0.8-1.0 grams, and those who lift weights consume 1.0-1.2 grams.

Two Signs Your Meals are Too High in Protein for Keto

Although the quickest way to establish your optimal protein intake is with blood-ketone testing, there are also two symptoms that may indicate you've gone too far:

• Your breath starts smelling like nail polish remover, overripe fruit, or ammonia.
• You experience flu-like symptoms, such as headaches, fatigue, and nausea, as your body adjusts to extremely low levels of carbohydrates.

The Importance of Protein on the Keto Diet

Getting the right amount of protein every day is crucial to the success of the keto diet. Protein helps increase calorie burning while decreasing cravings and hunger levels. It also helps maintain and build muscle mass, which improves quality of life.

How to Meet Your Protein Needs: Top Keto Protein Sources

To meet your protein needs on the keto diet, consider adding the following keto-approved protein sources to your meals:

• Fish, preferably wild-caught fatty fish like salmon, tuna, and mackerel
• Shellfish, such as clams, oysters, lobster, and crab
• Whole eggs
• Fattier cuts of ground beef, steak, roasts, and stew meat
• Pork, including ground pork, pork chops, tenderloin, and ham
• Poultry, such as chicken, duck, turkey, and quail
• Offal/organ meats, such as heart, liver, kidney, and tongue
• Bacon and sausage (check labels for sugar and fillers)
• Nut butter, such as natural, unsweetened almond or macadamia nut butter
• Full-fat cheese, such as cheddar, mozzarella, and parmesan
• Keto-friendly protein powders, such as grass-fed whey protein, collagen protein, and pea protein isolate

Aim for 1.2-2.0g of protein per kg of body weight

This is a widely recommended protein intake range for people on keto. It is thought to help preserve muscle mass, improve body composition, and provide other health benefits.

Protein is an essential macronutrient with a wide range of functions in the body. It is made up of amino acids, nine of which are "essential", meaning they must be obtained from food.

The keto diet is a very low-carbohydrate, high-fat, and moderate-protein diet. It is thought to increase the body's efficiency at burning fat for energy, but it can be challenging to adhere to due to the restrictions involved.

There is a concern that too much protein can prevent ketosis by causing a condition called gluconeogenesis. However, this is unlikely to interfere with ketosis unless you are consistently consuming a lot more protein than recommended.

Not getting enough protein can lead to decreased muscle mass and struggles with weight.

Who might need more protein on keto?

• People looking to maintain muscle mass while losing weight
• Anyone at risk of slow wound healing
• Older adults looking to remain active and healthy
• Type 2 diabetics and those with cardiovascular risk factors
• People engaging in resistance training

Who might need less protein on keto?

People on keto diets for therapeutic purposes, such as managing certain cancers

Resistance training increases protein requirements

The body needs protein to repair and build muscle. Resistance training increases the body's protein requirements, as the muscles need to repair and rebuild. The amount of protein required depends on the individual's goals. Those looking to build muscle mass will require more protein than those looking to lose weight.

For those looking to build muscle, a protein intake of 1.6 g/kg/day may help increase muscle mass. This is based on research that found that a total protein intake of up to about 1.6 g/kg/day may help increase muscle mass.

For those looking to lose weight, a higher protein intake of 2.4 to 3 g/kg per day may be beneficial. This is because a calorie deficit is required to lose weight, and a higher protein intake can help preserve or build lean muscle mass.

It is important to note that even with rigorous training, there is a limit to how quickly muscle mass can increase, regardless of protein consumption.
