The ketogenic diet is a low-carb, high-fat diet that aims to drive the body into a metabolic state called ketosis, where the body uses fat instead of carbohydrates as its primary energy source. 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 is important to note that the keto diet may not be suitable for everyone, and it is always recommended to consult with a doctor or dietitian before starting any new diet plan. While on a keto diet, it is crucial to monitor your carbohydrate intake and choose your carbs wisely. Meat, poultry, eggs, fish, and shellfish are popular keto-friendly options as they are rich in protein and have zero or very low carbohydrates. Additionally, nuts, seeds, avocados, and most cheeses are excellent choices as they are high in fat and low in carbs.
| Characteristics | Values |
|---|---|
| Carbohydrates | Very low intake, generally under 20-40 grams per day |
| Fats | High intake, especially from animal proteins, dairy, nuts, seeds, and oils |
| Proteins | Moderate intake, with animal proteins and eggs recommended |
| Calories | Not explicitly mentioned, but implied to be moderate to high due to fat and protein content |
| Food Choices | Limited variety, with some foods off-limits; includes meat, poultry, fish, eggs, cheese, nuts, seeds, and certain fruits and vegetables |
| Health Benefits | Weight loss, blood sugar control, potential prevention of cancers and neurodegenerative conditions |
| Health Risks | Potential nutrient deficiencies, increased "bad" cholesterol, associated with higher risk of cardiovascular disease |
| Individual Variation | Results may vary, and working with a dietitian is recommended to ensure adequate nutrition |

What You'll Learn
High-fat foods like cheese, eggs, and meat
High-fat foods are a cornerstone of the keto diet, and cheese, eggs, and meat can all fall into this category.
Cheese is a staple in many keto diets due to its low carbohydrate content and high-fat content. Cheddar, mozzarella, feta, cream cheese, brie, goat cheese, blue cheese, parmesan, gouda, provolone, Swiss, and cottage cheese are all keto-friendly options. Cheese can be incorporated into keto meals in a variety of ways, such as in meat dishes, snacks, salads, pizza crusts, and casseroles. The amount of cheese consumed should be monitored to align with individual calorie intake and dietary goals. Research suggests that including cheese in a keto diet can enhance satiety and contribute to weight loss.
Eggs are another food group that is commonly associated with keto diets. The "egg fast" is a very restrictive, short-term ketogenic diet that encourages the consumption of eggs. This diet promotes weight loss by restricting calories and inducing ketosis, a metabolic state in which the body uses ketones derived from fat as its primary fuel source. While the egg fast has not been extensively studied, some research suggests that ketogenic diets may promote more weight loss than conventional low-fat diets.
When it comes to meat, the ketogenic diet favours fatty cuts with higher levels of fat. Examples include chicken thighs, ground beef with a higher fat ratio, and beef cuts like New York Strip and ribeye. Grass-fed and pastured meats are recommended due to their higher nutrient content and beneficial fats, including omega-3 fatty acids. These meats can be cooked in fats like lard, tallow, avocado oil, ghee, butter, or coconut oil, and paired with other keto-friendly foods like avocado, eggs, and low-carb vegetables.
In summary, high-fat foods like cheese, eggs, and meat are integral to a strict keto diet. They provide essential nutrients, enhance satiety, and promote ketosis, which is the body's metabolic state of burning fat for energy instead of glucose or carbohydrates.

Fish and shellfish
Salmon is a popular choice for those on the keto diet, as it is nearly carb-free and packed with protein and healthy fats. A 3.5-ounce serving of Atlantic salmon provides 21 grams of protein and 4.4 grams of healthy fats, including Omega-3 fatty acids. The fatty acid profile of salmon varies depending on whether it is wild-caught or farm-raised, with farm-raised salmon being fattier. Salmon is a versatile fish that can be grilled, broiled, or baked. A simple preparation involves brushing the filet with olive oil and sprinkling it with salt and pepper.
Mahi-mahi is another delicious option for keto dieters. It is a white fish with a mild, sweet flavour and a firm, smooth texture. Mahi-mahi is low in fat but high in protein, with 24 grams per serving. It is also an excellent source of Omega-3 fatty acids and B vitamins. This versatile fish can be grilled, baked, or pan-fried and used in various recipes calling for white fish.
Other fish options for keto dieters include tuna, which is rich in selenium, vitamin B12, vitamin D, and fatty acids, and flounder, a leaner fish with a delicate, slightly sweet taste. Flounder is a good choice for those who don't prefer a "fishy" flavour but still want the health benefits of seafood. It provides 12 grams of protein and 2 grams of fat per 100-gram serving.
When it comes to shellfish, scallops and shrimp are excellent choices for the keto diet. Scallops, whether bay or sea scallops, are a good source of protein, with 19 grams per 100-gram serving, while shrimp provide 13 grams of protein. Shrimp have a higher cholesterol level of 125mg, so it is important to add variety to your shellfish choices.

Animal proteins like chicken
Animal proteins are a staple of the keto diet. Meat and poultry contain no carbs and are rich in B vitamins and several other important minerals. They are also a great source of high-quality protein, which may help preserve muscle mass during a very low-carb diet.
Chicken is a popular choice when it comes to animal protein on keto. Chicken breast is a leaner cut of meat, so it is recommended to cook it using a method that adds fat, such as braising or frying in butter. Chicken thighs are fattier and can be cooked using a variety of methods, such as grilling or baking.
When choosing animal protein sources for keto, it is recommended to look for fatty cuts of meat, as these will provide plenty of protein and help you meet your fat intake goals. In addition to chicken, other good sources of animal protein for keto include pork, beef, and seafood.
It is important to note that the quality of the meat can also impact its nutritional value. If possible, choose meat from animals that were grass-fed or pasture-raised, as this tends to be higher in omega-3 fats and conjugated linoleic acid (CLA) than meat from grain-fed or factory-farmed animals.
While animal protein is an important part of the keto diet, it is not necessary to eat meat at every meal. Eggs and dairy products, such as cheese, Greek yogurt, and cottage cheese, are also good sources of protein and can be included in the keto diet.

Vegetables like broccoli
Broccoli is a keto-friendly vegetable that should be a staple on the keto diet. It is a superfood with only 2 grams of net carbs per 1/2 cup. Broccoli is also a good source of flavonoids, which are natural substances with antioxidant properties that can fight viruses and bacteria. The nutrients found in broccoli may prevent inflammation and reduce the risk of chronic diseases.
Raw broccoli has about 4 grams of net carbs per 100 grams, while cooked broccoli has about 3 grams. The difference in carb content is due to the increase in water content in cooked vegetables.
When preparing broccoli, you can steam, fry, roast, or bake it. You can also drizzle cheese sauce over it or add bacon for extra flavour. Broccoli can be a great substitute for pasta, rice, or potatoes in your meals.
Other vegetables that are good for a keto diet include cauliflower, cabbage, avocado, tomatoes, and olives. These vegetables are low in carbohydrates and provide plenty of nutrients. Cauliflower, in particular, has a mild flavour and is very versatile. It can be used as a base for dishes like cauliflower rice or mash. Avocado, though technically a fruit, is another excellent source of healthy fats and nutrients. It can be sliced, mashed, or baked according to your preference.

Nuts and seeds
Chia seeds are another popular keto option. They are packed with healthy fiber and omega-3 fats, which offer powerful anti-inflammatory properties. You can make chia pudding by soaking them in liquid for several hours until they take on a jelly-like texture, or you can add them to smoothies or protein shakes. Flax seeds are another good choice, as they are full of fiber and omega-3 fats. Make sure to grind your flax seeds so that you can get all of their benefits, as whole flax seeds will pass through your body undigested. You can add flax to your keto shake or smoothie, or use it to replace eggs in your baked goods.
Hemp seeds are another great option, which can be added to salads or protein shakes for a little nutty flavor. Pumpkin seeds are the number-one pick if you're looking for a protein boost, with nine grams per 1/4 cup serving. They are also a great source of zinc, an essential mineral involved in immunity, protein synthesis, wound healing, and growth and development. Brazil nuts are another good option, as just one nut provides more than 100% of your daily needs for selenium. However, due to their exceptionally high selenium content, it’s best to limit your intake to one to three Brazil nuts a day.
