The keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. The diet typically includes animal proteins, dairy, vegetables, plant-based foods, and fats and oils. More specifically, foods such as salmon, sardines, mackerel, and other fatty fish are recommended due to their high levels of omega-3 fats. Meat and poultry are also considered staple foods on the keto diet as they are rich in B vitamins and minerals and are a great source of high-quality protein. Other foods to eat on a keto diet include eggs, cheese, nuts, seeds, and oils such as olive and coconut.

Poultry is also a good option for keto as it is high in protein and low in carbs. Chicken and turkey are examples of poultry that can be included in the keto diet.

Fish and shellfish
When it comes to shellfish, shrimp and lobster are keto-friendly options. However, it is important to note that the carb count in shellfish can vary by type, so tracking carb intake is important to stay within the desired range. For example, squid and octopus tend to have a higher carb count than other types of shellfish.
Fish is not only a good source of protein and healthy fats, but it also provides important vitamins and minerals. It is rich in B vitamins, potassium, and selenium, making it a nutritious addition to a keto diet.
When preparing fish and shellfish on a keto diet, consider cooking them in oils like olive oil or butter, as these are also high-fat and low-carb options. Additionally, pairing fish with avocado, a healthy monounsaturated fat source, can further enhance the keto benefits of the meal.
Overall, fish and shellfish are versatile and nutritious options for a keto diet, offering a range of health benefits while keeping carb intake low.

Another good option is plain Greek yogurt and cottage cheese, which are high in protein and have some carbs. These can be eaten in moderation on a keto diet and can help decrease appetite and promote feelings of fullness. Cream is another dairy product that is very low in carbs and high in fat, making it ideal for keto. Half-and-half, a mixture of cream and whole milk, is also a good option.
Butter is another fatty dairy product that can be easily incorporated into a keto diet. It has very few carbohydrates and is rich in conjugated linoleic acid, which may aid in weight loss. Additionally, full-fat dairy alternatives, such as heavy cream and full-fat cheese, are recommended to accompany protein-rich meals on a keto diet.
Overall, dairy products are a valuable component of a keto diet due to their high-fat and low-carbohydrate content. They can be consumed in various forms, including cheese, yogurt, cream, and butter, to support a balanced and nutritious keto diet.

Vegetables
The keto diet is a high-fat, low-carbohydrate diet. Vegetables that are low in carbohydrates are a good source of nutrition on a keto diet.
Non-starchy vegetables like broccoli, bell peppers, and zucchini are recommended. Dark, leafy greens, such as spinach, kale, and collard greens, are also good options as they are low in carbs and calories, and high in fibre and vitamins.
Avocados are another vegetable that is widely recommended as part of a keto diet. They are high in healthy, monounsaturated fats and low in carbohydrates. They are also a good source of potassium, fibre, and various vitamins and antioxidants.

Nuts and seeds
Some nuts and seeds are better suited for a keto diet than others. For example, pecans, Brazil nuts, macadamia nuts, and peanuts are all recommended due to their low carbohydrate content and high fat content. Pecans, in particular, have been linked to a reduced risk of cardiovascular disease and diabetes. Macadamia nuts are also perfect for the keto diet because they are very high in fat, with one study finding that consuming 15% of calories from macadamia nuts led to a reduction in LDL cholesterol and an increase in HDL cholesterol.
Brazil nuts are an excellent source of selenium, which is critical for thyroid health, reproduction, DNA synthesis, and protection against various diseases. However, due to their exceptionally high selenium content, it is recommended to limit consumption to one to three Brazil nuts per day to avoid negative health effects. Chia seeds and flax seeds are also keto-friendly options, as they are packed with healthy fibre and omega-3 fats. Chia seeds can be added to smoothies, protein shakes, or used in keto cracker recipes, while flax seeds can be added to keto-friendly baked goods, soups, or smoothies.
Pumpkin seeds, walnuts, and sesame seeds are also keto-friendly options that can be enjoyed in moderation. Walnuts, in particular, have been linked to improved heart health, with studies showing that consuming 15% of calories from walnuts led to reduced levels of LDL cholesterol and blood pressure.
It is important to note that some nuts and seeds, such as cashew nuts and pistachios, are high in carbohydrates and should be avoided or consumed in moderation on a keto diet. Additionally, nuts and seeds can be challenging for some people to digest due to their high phytic acid content, but this can be improved by soaking them in water overnight.
