The keto diet is a low-carb, high-fat diet that can help with weight loss, blood sugar management, and the prevention of cancers and neurodegenerative conditions. It involves eating foods such as meat, seafood, dairy, eggs, nuts, fats, oils, and low-carb vegetables. The diet is based on the principle of ketogenesis, where the body uses fat as its primary source of energy instead of carbohydrates. This means that those on the keto diet should aim to consume less than 20 grams of net carbs per day, with net carbs being the total carbs minus fibre. While on the keto diet, it is important to be mindful of specific foods that are rich in carbohydrates and avoid them, such as baked goods and certain fruits.
| Characteristics | Values |
|---|---|
| Carbohydrates | Very low intake, less than 20 grams of net carbs per day |
| Fats | High intake, 70-80% of total calorie intake |
| Proteins | Moderate intake, 10-20% of total calorie intake |
| Animal Proteins | Meat, poultry, fish, and shellfish are recommended |
| Dairy | Cheese, eggs, and yogurt are allowed |
| Vegetables | Non-starchy, low-carb veggies like zucchini, cauliflower, bell peppers, and broccoli |
| Fruits | Limited, but berries like blackberries, raspberries, and strawberries are allowed |
| Nuts and Seeds | Macadamia, almonds, pecans, walnuts, sesame seeds, pumpkin seeds, and flaxseeds |
| Oils | Olive oil and other healthy oils |
| Alcohol | Low-carb drinks like dry wine or sugar-free beverages |

What You'll Learn
Eat high-fat, low-carb foods
The keto diet is a low-carb, high-fat diet. The diet works by getting your body to change its source of energy from carbohydrates to fat. This is called ketogenesis, and it usually begins about 3 to 4 days after you start restricting your carb intake.
On the keto diet, you'll be eating meats, fats, and oils, as well as some non-starchy or low-carb vegetables. About 70 to 80 percent of your calorie intake will come from fats, 10 to 20 percent from protein, and 5 to 10 percent from carbohydrates.
Meat and poultry are considered staple foods on the keto diet. They contain no carbs and are rich in B vitamins and minerals. Fish and shellfish are also keto-friendly. Salmon and other fatty fish are not only carb-free but also high in omega-3 fats, which are linked to improved brain health and a decreased risk of disease.
Avocados are another popular choice on the keto diet, as they are high in fat and low in net carbs (total carbs minus fiber). Other low-carb vegetables include zucchini, cauliflower, bell peppers, and broccoli.
Seeds and nuts are also great keto-friendly snacks. Macadamias, almonds, pecans, walnuts, sesame seeds, pumpkin seeds, and flaxseeds are all low in carbohydrates while being high in protein and healthy fats.
It's important to note that the keto diet can be challenging and may not be suitable for everyone. It's always a good idea to consult with a healthcare professional or dietitian before starting any new diet.

Consume animal proteins, dairy, vegetables, plant-based foods, and fats/oils
Consuming animal proteins is an important part of the keto diet. Meat and poultry are considered staple foods, as they are rich in B vitamins and minerals, and they are carb-free. Fish and shellfish are also keto-friendly, as they are nearly carb-free. Fatty fish like salmon, sardines, and mackerel are high in omega-3 fats, which are linked to improved brain health and a reduced risk of disease.
When it comes to dairy, there are some considerations. Dairy is often used as a crutch during the keto diet, as there are many high-fat dairy options, such as butter, cream, and cheese. However, some people choose to go dairy-free while on keto, as dairy is one of the most common inflammatory foods. Removing dairy from the diet can lead to a greater focus on nutrient-dense foods like eggs, meats, nuts, and olive oil. Additionally, plain Greek yogurt and cottage cheese are high-protein options that can be consumed in moderation on keto.
Vegetables are an essential component of the keto diet, but not all vegetables are created equal. The best keto vegetables tend to grow above ground, as root vegetables are typically higher in starch and carbs. Leafy salad greens and other non-starchy vegetables are recommended, as they provide the body with antioxidants, fiber, and a low number of carbs. Some keto-approved vegetables include zucchini, asparagus, broccoli, and cauliflower.
Plant-based foods are also an option on the keto diet. A plant-based keto diet can be challenging to follow long-term due to its restrictive nature, but it can be a healthy and sustainable practice centered around balance. It is recommended to opt for organic foods and limit non-fermented soy products.
Finally, fats and oils are a crucial part of the keto diet, as it is a high-fat, low-carb diet. The majority of dietary fat should come from sources of monounsaturates and saturates. Omega-3 and omega-6 fats are essential fatty acids, but it is important to be mindful of the amount of omega-6 consumed, as too much can be detrimental. High omega-6 oils include corn, soybean, cottonseed, peanut, and older versions of safflower and sunflower oils.

Avoid foods that are high in carbohydrates
The keto diet is a low-carb, high-fat diet that aims to drive your body into a metabolic state called ketosis, in which your body burns stored fat as a source of energy instead of carbohydrates. To achieve ketosis, you should aim for a total carbohydrate intake of under 20 to 40 grams of carbohydrates per day. This can vary depending on individual factors such as activity levels, with some people maintaining ketosis with up to 50 or even 60 grams of net carbs per day.
To stay within this low carbohydrate range, it is crucial to avoid foods that are high in carbohydrates. Cereal, crackers, rice, pasta, bread, and beer are all high in carbohydrates and should be avoided or limited. Even whole-wheat pasta and bean-based pasta are high in carbs, so it is important to consider alternatives like spiralized vegetables or shirataki noodles, which are lower-carb options.
Non-starchy vegetables can be excellent substitutes for high-carbohydrate foods. For example, cauliflower can be used to make "rice," and zucchini can be turned into noodles. Other low-carb, high-fiber vegetables include bell peppers, broccoli, and avocados, which are also rich in healthy fats and nutrients.
In addition to the above, it is important to note that even some healthy and nutritious foods are high in carbohydrates and should be avoided or limited on a keto diet. These include whole grains, fruits, legumes like lentils and chickpeas, and certain vegetables. While some berries and fruits can be included in moderation due to their lower carb content, it is crucial to monitor your total carbohydrate intake to ensure you stay within the keto guidelines.

Eat plenty of meat, seafood, eggs, and nuts
The keto diet is a low-carb, high-fat, and moderate-protein diet. It involves getting your body to use fat as its primary energy source instead of carbohydrates. This shift in metabolism is called ketogenesis and usually occurs within 3 to 4 days of starting the diet.
Meat, seafood, eggs, and nuts are all recommended foods when following the keto diet. Meat and poultry are considered staple foods on the keto diet. They contain no carbs and are rich in B vitamins and minerals. Meat is also a great source of high-quality protein, which may help preserve muscle mass during a very low-carb diet. Chicken, pork, steak, ground beef, lamb, bacon, turkey, ham, and sausage are all keto-friendly meats, although sausage should be consumed in limited amounts.
Fish and shellfish are also keto-friendly. Salmon and other fatty fish like mackerel and sardines are excellent sources of omega-3 fats, which have various health benefits, including improved blood sugar management and brain health. It is important to note that while shellfish is also low-carb, the carb count varies by type.
Eggs are a popular keto breakfast option, and they are a great source of protein. Nuts are another excellent snack or meal addition while on the keto diet. They are high in healthy fats and low in carbohydrates, fitting well within the high-fat, low-carb, and high-protein aspects of the keto diet. The best nuts to consume on keto include macadamias, almonds, pecans, and walnuts.

Consider a vegan keto diet
The ketogenic diet is a high-fat, low-carb, moderate-protein diet that is well-known for its effectiveness in weight loss, blood sugar control, and reduced risk of heart disease. While it is often associated with animal foods, the keto diet can be adapted to fit plant-based meal plans, including vegan diets.
The vegan keto diet is a low-carb, high-fat, moderate-protein diet that excludes all animal products while keeping carbohydrates to a minimum. The goal is to reach ketosis, a metabolic state where the body burns fat for fuel instead of carbohydrates. To follow this diet, about 70-80% of your calories should come from fats, 15-25% from plant-based proteins, and 5-10% from carbs, usually no more than 35-50g of net carbs per day.
Healthy fats to include in a vegan keto diet are avocados, coconut oil, olive oil, MCT oil, nuts, and seeds. For plant-based proteins, consider tofu, tempeh, seitan, hemp seeds, and pumpkin seeds. Dairy substitutes such as coconut yogurt, cashew cheese, and almond milk can also be consumed. In addition, low-carb vegetables such as leafy greens, zucchini, cauliflower, mushrooms, and bell peppers are a great option.
It is important to note that a vegan keto diet may be more challenging to follow due to the exclusion of animal-based foods, which are typically high in fat and often consumed on a keto diet. However, with careful planning, vegans can reap the potential benefits of a ketogenic diet. Some potential challenges to consider are nutrient deficiencies, such as vitamin B12, vitamin D, iron, and omega-3s, as well as digestive issues due to low fiber intake.
If you are considering a vegan keto diet, it is recommended to work with a Registered Vegan Dietitian to ensure you are meeting all your nutrient needs and make adjustments based on your individual requirements.
