The ketogenic diet, also known as the keto diet, is a low-carb, high-fat diet that has been around since the 1920s. It involves drastically reducing carbohydrate intake and replacing it with fat, typically deriving 70-80% of total calories from fat. The diet restricts total carbohydrate intake to less than 50 grams per day, with about 5-10% of energy intake coming from carbohydrates. Protein intake is also moderated to prevent the body from using protein instead of fat as its primary fuel source. The goal of the ketogenic diet is to induce a metabolic state called ketosis, where the body uses fat as its primary fuel source instead of carbohydrates, leading to weight loss and improved metabolic health. While the diet has been shown to be effective for weight loss, it can be challenging to meet nutritional needs and may have negative impacts on heart health due to the high-fat content.

What You'll Learn
High-fat foods like fatty meat, fish, nuts, cheese, and butter
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where the body uses fat as its primary fuel source instead of carbohydrates.
Nuts are a great source of healthy fats and can be easily incorporated into a keto diet. Studies have shown that a higher intake of nuts is associated with a reduced risk of heart disease and deaths associated with cancer, diabetes, and respiratory illnesses. Almonds, walnuts, pecans, pistachios, cashews, and Brazil nuts are all good choices.
Cheese is another good high-fat, low-carb option for keto dieters. However, it is also high in saturated fat, so it should be consumed in moderation. Butter is another food source of butyrate, which may play a role in promoting brain health.
Fatty fish like salmon, tuna, anchovies, and sardines are also excellent sources of good-for-you fats and are keto-friendly.

Low-carb foods like non-starchy vegetables and leafy greens
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where the body uses fat as its primary fuel source instead of carbohydrates.
Low-carb vegetables are an important part of a ketogenic diet. While it can be tricky to get enough vegetables while staying within the recommended 20 to 50 grams of carbohydrates per day, there are many keto-friendly vegetables that are packed with important nutrients, vitamins, and minerals.
Some of the best low-carb vegetables to include in a ketogenic diet are leafy greens such as spinach, kale, lettuce, cabbage, and Swiss chard. These vegetables are not only low in carbs but also provide important nutrients like potassium, iron, calcium, and vitamin C. For example, a cup of spinach contains only 1.1 grams of total carbs and 0.4 grams of net carbs, while also providing 0.9 grams of protein and 0.1 grams of fat. Similarly, a cup of shredded raw cabbage contains 4.1 grams of total carbs and 2.3 grams of net carbs, along with 0.9 grams of protein and 0.1 grams of fat.
Other low-carb vegetables to consider are zucchini, cucumbers, asparagus, celery, tomatoes, eggplant, and bell peppers (especially green ones). These vegetables can be prepared in a variety of ways and are versatile enough to be added to salads, sandwiches, or cooked dishes. For example, zucchini noodles can be a great low-carb alternative to pasta dishes, and riced cauliflower can replace traditional rice.
By incorporating these low-carb vegetables into a ketogenic diet, individuals can ensure they are getting the necessary nutrients while maintaining the state of ketosis needed for effective weight loss and improved metabolic health.

Moderate protein intake, such as fish and meat
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where the body utilizes fat as its primary fuel source instead of carbohydrates.
The standard ketogenic diet (SKD) is a very low-carb, moderate-protein, and high-fat diet. The protein amount on the ketogenic diet is kept moderate in comparison with other low-carb high-protein diets, because eating too much protein can prevent ketosis. The amino acids in protein can be converted to glucose, so a ketogenic diet specifies enough protein to preserve lean body mass, including muscle, but that will still cause ketosis.
When following a ketogenic diet, it is important to moderate your protein consumption. This is because protein can be converted into glucose if consumed in high amounts, which may slow your transition into ketosis. The recommended protein intake on the ketogenic diet is less than 1 gram per pound of body weight, with the option to increase to 1.5 grams per pound for individuals engaged in heavy exercise involving weight training. This limitation on protein intake aims to prevent endogenous glucose production through gluconeogenesis.
Meat and fish are excellent sources of moderate protein intake on the ketogenic diet. Fatty cuts of meat, such as beef, poultry, and pork, are recommended. Wild-caught fish, including mackerel, tuna, salmon, trout, halibut, cod, catfish, and mahi-mahi, are also good options. Organ meats, such as heart, liver, tongue, and kidney, are another source of moderate protein. It is important to include a variety of these meats and fish in your diet to ensure adequate intakes of fiber, B vitamins, and minerals like iron, magnesium, and zinc.

Avoid foods with high sugar content
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where the body uses fat as its primary fuel source instead of carbohydrates.
To follow the ketogenic diet, it is important to avoid foods with high sugar content. Sugar is a carbohydrate, and carbohydrates are the body's preferred source of energy. On a ketogenic diet, only 5% to 10% of energy intake should come from carbohydrates. This equates to a maximum of 50 grams of carbohydrates per day, or even as low as 20 grams per day.
Foods with high sugar content include grains, beans, fruits, and starchy vegetables. Sugar is also often added to processed foods, such as sauces, condiments, and baked goods, so these should be avoided or limited on a ketogenic diet. It is important to read nutrition labels to identify added sugars.
When avoiding foods with high sugar content, it is important to ensure you are still getting essential nutrients. The ketogenic diet can be restrictive, and it can be challenging to meet nutritional needs. Work with a registered dietitian nutritionist (RDN) to ensure you are getting enough vitamins, minerals, and fiber while maintaining ketosis.

Potential health benefits, such as reduced risk of type 2 diabetes, heart disease, and cancer
The ketogenic diet is a very low-carbohydrate, high-fat diet that causes weight loss and provides numerous health benefits. When following a ketogenic diet, one typically limits their carb consumption to 20 to 50 grams per day and fills up on fats such as meat, fish, eggs, nuts, and healthy oils. This reduction in carbohydrates puts the body into a metabolic state called ketosis, where it becomes very efficient at burning fat for energy.
The ketogenic diet has been found to be beneficial for people with type 2 diabetes. This is because the diet helps maintain blood sugar levels at a low but healthy level, minimising large fluctuations in blood sugar. This can positively affect several clinical markers of blood sugar control. Research has shown that the ketogenic diet may be as effective for weight loss as a low-fat diet, with one review finding that the ketogenic diet group lost an average of 2 pounds more than the low-fat diet group.
The ketogenic diet has also been found to be beneficial in the treatment and prevention of cancer. The diet mimics a fasting state by consuming high amounts of fat and protein and very low carbohydrates, which induces metabolic changes that reduce insulin, glucose, and glucagon levels. Cancer cells are dependent on glucose, so administering a ketogenic diet can effectively target this dependency. The ketogenic diet has been found to demonstrate a synergistic effect when combined with classical chemotherapy in the treatment of various cancers.
In terms of cardiovascular health, the ketogenic diet has been found to be beneficial in the short term. It can lead to a rapid reduction in body mass, triglyceride levels, Hb1Ac, and blood pressure. However, the long-term efficacy of the ketogenic diet for weight loss and metabolic changes is not significant, and a low-carb pattern is more beneficial than a very low-carb pattern in terms of cardiovascular mortality.
