The ketogenic diet, commonly known as the keto diet, is a low-carb, high-fat diet that has been associated with several health benefits. It involves drastically reducing carbohydrate intake and replacing it with fat, which puts your body into a metabolic state called ketosis. In ketosis, the body becomes more efficient at burning fat for energy, and this can lead to weight loss and improved blood sugar control. While on a keto diet, it is important to consume plenty of protein and healthy fats, such as those found in fish, meat, eggs, high-fat dairy, nuts, and certain vegetables. However, it is crucial to be mindful of potential risks, such as nutrient deficiencies, and to consult a healthcare professional before starting any new diet.

What You'll Learn
High-fat foods like bacon, cheese, and avocados
The ketogenic diet, or keto, is a low-carbohydrate, high-fat diet. The diet involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where your body becomes very efficient at burning fat for energy.
Avocados are another food that fits well within the keto diet due to their healthy fat content. One-third of an avocado provides 8 grams of total fat, 6 grams of healthy fats, and only 4 grams of carbohydrates. Avocados can be eaten alone or included in a variety of dishes such as salads, soups, desserts, sauces, and guacamole.
Cheese is also a keto-friendly food. Since the keto diet is a high-fat, moderate-protein, and low-carb diet, cheese can be a perfect fit. When choosing a cheese to eat on the keto diet, opt for high-quality, grass-fed, and full-fat varieties. Goat cheese is an excellent choice as it contains zero carbs, 8 grams of fat, and 6 grams of protein per ounce. Grated Parmesan is another good option, as it is often used in small quantities to add flavor to dishes.

Fish and seafood
Salmon is a fatty fish that is rich in omega-3 fatty acids and protein. It is a popular choice for those on the keto diet due to its nutritional profile and versatility in cooking. A 3.5-ounce (100-gram) serving of Atlantic salmon provides 21 grams of protein, 4.4 grams of fat, and absolutely no carbs. The fatty acid profile of salmon varies depending on whether it is wild-caught or farm-raised, with the latter being fattier. Salmon can be grilled, broiled, or baked and seasoned with olive oil, salt, and pepper for a simple yet tasty dish.
Mahi-mahi is another fish option that has a sweet, mild flavor and a firm, smooth texture. It can be prepared similarly to salmon by baking, broiling, or grilling. Flounder is a leaner fish compared to salmon, with a lighter and flakier texture. It has a delicate, slightly sweet taste, making it a good choice for those who are not fond of a strong "fishy" flavor. Flounder provides 12 grams of protein and 2 grams of fat per 100-gram serving.
Scallops, particularly bay scallops, are a great keto option as they pack 19 grams of protein into a 100-gram serving. Shrimp is also a good choice, providing 13 grams of protein, but it is important to note that they have lower levels of healthy fats and higher cholesterol levels compared to other seafood options. For those who enjoy a variety of seafood, octopus is another keto-friendly choice, but it is important to track the carb intake from this source.
In addition to their nutritional benefits, fatty fish like salmon, sardines, and mackerel are excellent sources of omega-3 fatty acids, which have been linked to improved brain health and a reduced risk of certain diseases. Omega-3 fats may also help manage blood sugar levels and lower insulin levels in people with diabetes. Therefore, incorporating these types of fish into a keto diet can provide additional health benefits beyond weight loss.

Instead, choose plain vegetables and add your own keto-friendly seasonings and fats, such as avocado or olive oil.
You can incorporate these non-starchy vegetables into your keto meals in a variety of ways. For example, you can add them to omelets, salads, or stir-fries.
