The keto diet is a high-fat, very low-carbohydrate, and moderate-protein diet. It is designed to force the body to burn fat for energy instead of carbohydrates, which is known as ketosis. While the keto diet has become popular for weight loss, it was originally developed to treat epilepsy. On the keto diet, you can eat meat, fish, eggs, dairy, vegetables, nuts, seeds, and high-cocoa chocolate. However, it's important to make sure you get enough fibre and limit your intake of fruit and starchy vegetables.

What You'll Learn
Meat and Poultry
When choosing meat and poultry on a keto diet, opt for plain, unprocessed, and fatty cuts. Grass-fed and pasture-raised animal meat is recommended as it contains higher-quality fats and protein and can keep you full for longer. Examples of good meat and poultry options include:
- Beef
- Pork belly
- Ribeye steak
- Chicken thighs
- Baby back ribs
- Turkey
- Chicken
- Duck
- Game hen
- Goose
Processed meats, such as bacon, sausage, and ham, are allowed on keto but should be limited as they are not the best for heart health and may increase the risk of certain types of cancer.

Fish and Seafood
Salmon is a very popular choice for keto dieters due to its high fat content and versatility. A 3.5 oz (100g) serving of Atlantic salmon has 21 grams of protein, 4.4 grams of fat, and no carbs. It is also packed with potassium, selenium, and B vitamins. The fatty acid profile of salmon varies depending on whether it is wild-caught or farm-raised, with the latter being fattier. Salmon is extremely versatile and can be grilled, broiled, or baked.
Mackerel is another fatty keto-friendly fish that is loaded with omega-3 fatty acids and vitamin D. It is also an excellent source of supernutrients like vitamin B and selenium.
Mahi-Mahi is a great choice for those who want a mild-tasting fish with a firm, smooth texture. It is slightly less fatty than other fish but is still an excellent source of protein with no carbs. Mahi-Mahi can be baked, grilled, or broiled.
Other good options for keto-friendly seafood include shellfish such as shrimp, scallops, crab, mussels, and bay scallops. These are all low-carb options, with shrimp and most crabs containing no carbs at all. However, it is important to note that oysters and octopus do contain carbs, so these should be consumed in moderation on a keto diet.

Dairy and Dairy Alternatives
Cheese is a great fit for the keto diet. With hundreds of varieties to choose from, most cheeses are very low in carbohydrates and high in fat. For example, just one ounce (28 grams) of cheddar cheese provides one gram of carbohydrates, six grams of protein, and a good amount of calcium. Cheese is also a good source of conjugated linoleic acid (CLA), which has been linked to fat loss and improvements in body composition. Some studies even suggest that cheese may help protect against heart disease.
Plain Greek yogurt and cottage cheese are also suitable dairy options on the keto diet. These are high-protein foods that can help decrease appetite and promote feelings of fullness. They can be enjoyed as a snack on their own or combined with chopped nuts, cinnamon, or other spices for a quick keto treat.
Cream and half-and-half are also keto-friendly. These dairy products are very low in carbohydrates and high in fat, making them ideal for adding to coffee or using in cooking. Like cheese, they are rich in CLA, which may promote fat loss. However, it is recommended to consume them in moderation, as excessive intake of saturated fat may be linked to an increased risk of cardiovascular disease and stroke.
When it comes to plant-based milk alternatives, several options are available for those on a keto diet. Unsweetened soy, almond, and coconut milk are all suitable choices. It is important to avoid sweetened versions, as they contain too much sugar. Oat milk, even in its unsweetened form, is generally too high in carbohydrates to be considered keto-friendly.
In conclusion, dairy and dairy alternatives play an important role in the keto diet. Whether it's cheese, yogurt, cream, or plant-based milk, these options provide variety, essential nutrients, and help individuals adhere to the high-fat, low-carbohydrate requirements of the keto diet.
