First and foremost, keto-friendly foods should be high in healthy fats. This doesn't mean reaching for the nearest bag of potato chips or heading out for some fast food.

Instead, it involves incorporating foods that are rich in monounsaturated and polyunsaturated fats, such as avocados, olive oil, and fatty fish. These fats help keep your body in the state of ketosis, support heart health, and provide essential fatty acids that your body can't produce on its own.

Next, keto-friendly foods should contain a moderate amount of protein. While protein is an essential nutrient for building and repairing tissues, consuming too much can potentially kick you out of ketosis.

This is because excess protein can be converted into glucose in the body, which could shift your body's metabolism away from fat and toward carbohydrates. Foods like lean meats, poultry, fish, and eggs are excellent sources of protein that can be included in a keto diet.

Finally, keto-friendly foods should be very low in net carbohydrates. Net carbs can easily be calculated by subtracting the fiber content from the total carb count. Technically, fiber is a type of carbohydrate, but it doesn’t get digested and absorbed in the same way as other carbs.

Instead, it passes through the digestive system largely intact, so it doesn’t contribute to your overall net carb count. That means you can include a variety of fruits and vegetables in your diet as long as they’re high in fiber.
