The keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. It involves eating foods such as meat, poultry, fish, eggs, and non-starchy vegetables. The diet is designed to change the body's fuel source for energy from carbohydrates to fat, which is known as ketogenesis or ketosis. This diet is popular due to its potential benefits for weight loss, blood sugar management, and the prevention of cancers and neurodegenerative conditions. However, it can be challenging to maintain and may lead to nutrient deficiencies if not carefully managed.

What You'll Learn
High-fat foods like eggs, meats, avocados, and oils
The keto diet is a high-fat, low-carbohydrate diet. It involves eating foods that are high in fat and low in carbohydrates to reach a metabolic state called ketosis. In ketosis, the body breaks down stored fat to use for energy instead of carbohydrates.
High-fat foods are an essential part of the keto diet. Here are some examples of high-fat foods that are recommended on the keto diet:
Eggs
Eggs are a versatile and nutritious food that is low in carbohydrates and high in fat and protein. They are also a good source of B vitamins and antioxidants, which support eye health. It is recommended to eat whole eggs rather than just egg whites, as most of the nutrients are found in the yolk.
Meats
Meat is a staple food on the keto diet because it is naturally carb-free and high in protein. When following a ketogenic diet, it is important to choose leaner meats, such as skinless chicken and turkey, or grass-fed meat, which has more omega-3 fats and conjugated linoleic acid (CLA).
Avocados
Avocados are a fruit that provides a rich source of heart-healthy monounsaturated fatty acids (MUFAs) and fiber. They are also low in carbohydrates, making them a good choice for the keto diet. Avocados can be added to salads, smoothies, or breakfast plates.
Oils
Oils such as olive oil, coconut oil, and avocado oil are high-fat foods that are commonly used in the keto diet. Olive oil is high in oleic acid, a monounsaturated fat that supports heart health. Coconut oil is 100% fat and is used directly by the liver for energy. These oils can be used for cooking, dressing, or drizzling over meals.

Low-carb foods like non-starchy vegetables
The keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where the body starts breaking down stored fat into molecules called ketone bodies to use for energy.
Non-starchy vegetables are low in calories and carbohydrates but high in many nutrients, including vitamin C and several minerals. They also contain antioxidants that help protect against cell-damaging free radicals.
- Broccoli
- Cauliflower
- Green beans
- Bell peppers
- Zucchini
- Spinach
- Asparagus
- Brussels sprouts
- Kale
- Mushrooms
- Tomatoes
- Arugula
These vegetables can be prepared and cooked in various ways to make tasty and nutritious meals or snacks while on the keto diet. For example, keto-friendly recipes include stuffed red bell peppers filled with creamy eggs and spinach, zucchini fritters, and cauliflower risotto.
It is important to note that while on the keto diet, starchy vegetables such as corn, green peas, potatoes, parsnips, and carrots should be limited as they contain more carbohydrates.

Dairy products like butter, cream, and cheese
Similarly, grass-grazed raw cheese is an excellent source of fat and protein, with zero carbohydrates. Cheddar cheese, blue cheese, and mozzarella are good options, and consuming them raw provides the most nutritional benefits. Cheese is also a rich source of calcium and has been linked to reduced muscle mass loss and increased strength as we age.
Cream is another dairy product that pairs well with the keto diet. Grass-grazed raw cream is recommended, and it is often used to add flavour and texture to keto meals. Cream cheese, in particular, is a versatile ingredient that can be used in both sweet and savoury keto dishes, such as pancakes, frosting, and cheesecakes.
In addition to butter, cheese, and cream, other full-fat dairy products can be incorporated into the keto diet. Whole raw milk, Greek yogurt, and cottage cheese are nutritious options that can be consumed in moderation. These dairy products provide a range of health benefits and help promote feelings of fullness, making them a satisfying part of a keto meal plan.

Seafood like fish and shellfish
Seafood is a great option for those on the keto diet. Fish and shellfish are very keto-friendly, as they are nearly carb-free. Salmon, sardines, oysters, tuna, and mahi-mahi are all delicious and nutritious options. For example, oysters are a good source of omega-3 fatty acids, zinc, copper, and vitamin B12. Tuna is packed with essential nutrients like selenium, vitamin B12, vitamin D, and fatty acids.
It is important to note that while fish and shellfish are generally keto-friendly, the carb count in shellfish can vary by type. For example, crab and shrimp are very low in carbs, while octopus has a higher carb count. Therefore, it is important to carefully track carb intake to stay within the keto guidelines.
When it comes to seafood preparation on the keto diet, it is best to choose fatty fish and pair them with creamy, buttery sauces. Canned seafood is also a convenient option, especially when packed in oil. For example, you can make a keto-friendly shrimp scampi by removing the pasta and adding extra butter and cheese, serving it as a dip with cucumber slices or celery sticks.
In addition to being keto-friendly, seafood provides a range of nutrients. As mentioned earlier, seafood is a good source of omega-3 fatty acids, which are important for heart, brain, and eye health. It is also a great source of high-quality protein, which may help preserve muscle mass during a very low-carb diet.
Overall, seafood like fish and shellfish are excellent choices for those following the keto diet. They are not only keto-friendly but also offer a variety of nutritional benefits that can support overall health and well-being.

Fatty fish like salmon
The keto diet is a very low-carb, high-fat diet that is known to have numerous health benefits. It involves a reduction of carbs coupled with an increase in healthy fats, putting the body into a metabolic state called ketosis, which promotes weight loss and overall well-being.
Salmon is a versatile protein that can be prepared in various ways on the keto diet. It can be grilled, pan-seared, baked, or herb-crusted. For example, a simple keto meal could consist of half an avocado with a small piece of salmon cooked in olive oil, served with a side salad.
When shopping for salmon, it is important to look for fresh fish. Frozen salmon fillets or smoked salmon can also be convenient options for quick keto-friendly meals.
In addition to salmon, other fatty fish such as sardines and mackerel are also good choices on the keto diet, as they are high in omega-3 fats and may help manage blood sugar levels. It is recommended that adults consume 8 to 10 ounces of seafood per week.
