The keto diet is a high-fat, low-carb, moderate-protein diet that aims to help with weight loss, type 2 diabetes management, and the prevention of chronic illnesses. The standard keto macro ratio is 70-80% fat, 15-20% protein, and 5-10% carbs. However, there is flexibility depending on individual needs and goals. For example, those looking to lose weight may benefit from a higher protein intake, while those looking to gain muscle can increase their fat intake. It is important to ensure adequate protein intake to support muscle growth and repair, with keto-friendly sources including meat, poultry, seafood, eggs, and cheese.

Keto-friendly animal protein sources include meat, poultry, seafood, eggs and cheese
When following a keto diet, it's important to get the right balance of macronutrients ("macros") to ensure your body enters nutritional ketosis. This natural metabolic state is achieved by breaking down fat for energy instead of glucose from carbohydrates.
Keto-friendly animal protein sources include meat, poultry, seafood, eggs, and cheese. These foods are considered complete proteins as they contain all nine essential amino acids, which are required to be consumed daily as the body cannot produce them.
Meat is a versatile source of protein on a keto diet. Fatty cuts of steak, bacon, and pork belly are popular choices, with 80/20 ground beef and untrimmed ribeye steak being particularly favoured by keto enthusiasts. In addition to being protein-rich, these meats also contribute to the high-fat content required in a keto diet.
Poultry, such as chicken and turkey, is another lean protein option. When paired with fatty foods like olive oil, poultry can help boost your fat intake while providing essential amino acids.
Seafood is also an excellent source of protein and healthy fats on a keto diet. Fatty fish like salmon and mackerel are rich in omega-3 fatty acids, promoting heart health and reducing inflammation. Other seafood options include mussels, salmon roe, and oysters, which also provide a small amount of carbohydrates.
Eggs are a versatile and affordable keto-friendly animal protein. They are a complete protein, offering all the essential amino acids, and are rich in healthy fats, particularly when consumed whole.
Cheese is another keto-friendly dairy product that serves as a good source of protein. Hard cheeses, such as cheddar or parmesan, tend to have a higher protein content than softer varieties. Cheese also contains conjugated linoleic acid (CLA), which may aid weight loss and improve body composition.
While animal proteins are emphasized in a keto diet, it's worth noting that plant-based proteins like tofu, soy products, nuts, and seeds can also be incorporated. However, some of these options may be higher in carbohydrates, so it's important to monitor your intake to stay within the keto guidelines.

Keto-friendly plant protein sources include tofu, soy-based products, nuts and seeds
Tofu, soy-based products, nuts, and seeds are all great sources of plant-based protein for those on a keto diet.
Tofu is a soy-based product that is a complete protein, meaning it contains all nine essential amino acids. It has a fairly neutral flavour, so it's a versatile ingredient that can be used in a variety of dishes, such as stir-fries, soups, curries, and even sandwiches.
Other soy-based products that are keto-friendly include tempeh, which is made from fermented soybeans and has a nutty flavour, and edamame, which are immature soybeans often eaten as a snack.
Nuts are another excellent source of plant-based protein and also provide healthy fats, B vitamins, antioxidants, and minerals. Examples of keto-friendly nuts include peanuts, cashews, and almonds. Just be mindful of portion sizes, as nuts are calorie-dense.
Seeds are also a great way to get plant-based protein and healthy fats, like omega-3 fatty acids, into your keto diet. Examples of keto-friendly seeds include sacha inchi seeds, pumpkin seeds, hemp seeds, and chia seeds.
In addition to these plant-based sources, you can also get protein from vegetables like broccoli, spinach, asparagus, and mushrooms.
By incorporating a variety of these keto-friendly plant-based proteins into your diet, you can ensure you're getting all the essential amino acids your body needs while maintaining a state of ketosis.

Aim for at least 20 grams of protein at each meal
The keto diet is a high-fat, low-carb, and moderate-protein diet. It involves restricting your carb intake to 5% to 10% of your calories, which leads to an increase in fat intake to 55% to 70% of your calories, while the remaining 20% to 35% of your calories come from protein.
On a 2,000-calorie diet, this equates to consuming less than 50 grams of carbs each day, with a breakdown of 100-150 grams of protein and 156-178 grams of fat.
Research suggests that we need at least 15-25 grams of protein at each meal to stimulate muscle protein synthesis adequately. Therefore, it is recommended to aim for at least 20 grams of protein at each meal. This can be achieved by consuming:
- 100 grams (3.5 ounces) of meat, poultry, or fish (about the size of a deck of cards)
- 240 grams (8 ounces) of plain Greek yogurt
- 210 grams (7 ounces) of cottage cheese
- 100 grams (3.5 ounces) of hard cheese (about the size of a fist)
- 100 grams (3.5 ounces) of almonds, peanuts, or pumpkin seeds (about the size of a fist)
It is important to note that other nuts, seeds, and vegetables also provide a small amount of protein, ranging from 2-6 grams per average serving.
While 20 grams of protein per meal is a good guideline, it is not necessary to be overly concerned about hitting this target precisely. It is more important to focus on consuming a moderate amount of protein (1.2-2.0g/kg/day) and spreading it out over 2-3 meals. This amount of protein will help preserve muscle mass, improve body composition, and provide other health benefits.
Additionally, it is worth noting that resistance training increases your protein requirements. If you engage in weight lifting or other forms of resistance training, aim for a protein intake at or near the top of your range, especially if your goal is to gain muscle.
By incorporating these protein-rich foods into your meals and focusing on adequate protein intake, you can effectively meet your protein macro goals while following a keto diet.

A high-protein keto diet may not result in ketosis as your body may convert protein into glucose for fuel
The ketogenic diet is a low-carb, high-fat diet that is designed to put your body into a metabolic state called ketosis, where it burns fat (ketones) for energy instead of glucose. While the keto diet involves limiting your carb intake, it is also important to monitor your protein intake.
Protein is a necessary component of any diet as it is crucial for healthy brain function, skin, bone and muscle health, building muscle mass, and recovering after workouts. However, there is a lot of conflicting information about how much protein you should consume on a keto diet, and whether too much protein can prevent your body from entering ketosis.
Gluconeogenesis
Many low-carb, high-fat advocates believe that excess protein can turn into sugar in the bloodstream through a process called gluconeogenesis (GNG), which could knock down your ketone levels and prevent ketosis. GNG is a metabolic pathway that allows your liver and kidneys to make glucose from non-carbohydrate sources. While this is true, it is important to note that GNG is a necessary process that is already happening in your body and makes ketosis possible in the first place.
Your body takes compounds like lactate, amino acids (protein), and glycerol to manufacture glucose when there are no carbs around. GNG is an extremely stable process and it is not easy to increase it even with extra protein. Studies have shown that GNG production doesn't increase even with extra amino acids.
Generally, people following a keto diet need anywhere from 20 to 30% of their calories from protein. However, according to ketogenic diet experts Stephen Phinney and Jeff Volek, the most ideal way to calculate protein needs is in grams per kilograms of body weight (g/kg body weight). They recommend a target range of 1.2-2.0 g/kg body weight, depending on your lifestyle. For example, if you are a male who lifts heavy weights often, you may want to eat at the higher end of the protein range.
While it is theoretically possible for excess protein to kick you out of ketosis by increasing your blood sugar and insulin levels, this is unlikely to happen unless you are eating a very large amount of protein. This effect may be more common in people with type 1 diabetes. Sticking to the recommended protein guidelines of 1.2-2.0 grams per kilogram of target body weight should be adequate to support ketosis with no risk of breaking it.
In Summary
While it is important to monitor your protein intake on a keto diet, you are unlikely to break ketosis by consuming too much protein. In fact, eating adequate amounts of protein is beneficial on the ketogenic diet as it helps your body stay in fat-burning mode and provides other health benefits. The idea that too much protein will prevent ketosis is a myth.

Consume 0.8-1 gram of protein per pound of body weight
The keto diet is a high-fat, low-carb, and moderate-protein diet. The standard keto macro ratio is 5% or fewer calories from carbohydrates, 70-80% of calories from healthy fats, and 20-30% of calories from protein.
On a 2,000-calorie diet, this works out to be 25 grams of carbs or fewer, 156-178 grams of fat, and 100-150 grams of protein.
However, the exact ratio can vary depending on individual needs and goals. For example, those aiming for weight loss may need a higher percentage of calories from protein to support muscle growth and fat loss.
To determine the optimal protein intake for your specific needs, it is recommended to consume 0.8-1 gram of protein per pound of body weight. This range ensures that you are getting enough protein to support muscle growth and maintenance, as well as overall health and well-being.
- Include a variety of keto-friendly protein sources in your diet, such as meat, poultry, seafood, eggs, cheese, tofu, soy-based products, nuts, and seeds.
- Aim for at least 20 grams of protein at each meal. This amount is sufficient to stimulate muscle protein synthesis and support muscle growth and repair.
- If you are physically active or engaging in resistance training, you may need more protein. Consider aiming for the higher end of the recommended range, between 1.6-2.0 grams of protein per kilogram of body weight.
- Use a keto macro calculator to determine your specific protein needs based on your age, gender, activity level, and weight goals. This can help you create a personalized meal plan to ensure you are meeting your protein requirements.
- Plan your meals ahead of time and prepare meals in advance to ensure you are getting enough protein throughout the day.
- Consider using a simple journal or app to track your macros and ensure you are meeting your protein goals.
Remember, while protein is essential on a keto diet, it is also important to monitor your fat and carbohydrate intake to stay within the recommended keto macro ratios.

Frequently asked questions
Good sources of protein on a keto diet include meat, poultry, seafood, eggs, cheese, tofu, soy-based products, nuts, and seeds.
The amount of protein you should eat on a keto diet depends on your body weight, activity level, and health goals. A general recommendation is to consume 0.8-1 gram of protein per pound of body weight, or 1.2-2.0 grams of protein per kg of reference body weight. For a 2,000-calorie diet, this would translate to 100-150 grams of protein per day.
No, eating protein will not kick you out of ketosis. Gluconeogenesis, the process of converting amino acids to glucose, is demand-driven and will only occur if necessary. Research suggests that high-protein keto diets are compatible with weight loss and muscle maintenance.
Note: It is important to consult with a healthcare professional or nutritionist before starting any new diet, including a keto diet, to ensure it is safe and appropriate for your individual needs.
