The ketogenic diet is a high-fat, low-carb diet that has become increasingly popular in recent years. Although it usually includes animal products like meat, fish, and poultry, vegetarians can adapt it to fit their dietary needs. The vegetarian keto diet combines aspects of vegetarianism and keto dieting, with vegetarians eating animal products like eggs and dairy but avoiding meat and fish. While the traditional keto diet has plenty of protein, vegetarian keto requires a boost in this area, which can be achieved through eggs, dairy, nuts, seeds, and tofu.

What You'll Learn
The keto diet is a high-fat, low-carb diet
The ketogenic, or keto, diet is a high-fat, low-carb diet that has become increasingly popular in recent years. Although it usually contains animal products like meat, fish, and poultry, it can be adapted to fit a vegetarian diet. The keto diet is based on the principle of ketosis, a metabolic state in which the body burns fat for fuel instead of glucose. To achieve ketosis, the diet restricts carbohydrates and increases fat intake.
For vegetarians, the keto diet requires careful planning and consideration to ensure adequate nutrition. It is important to prioritise protein-rich vegetables while avoiding those with a high carb count. For example, spinach is a good source of protein and has a low carb content, whereas potatoes, while nutrient-dense, are too high in carbohydrates for the keto diet. Tofu and tempeh can also be important components of a vegetarian keto diet, providing versatility in preparation methods and allowing for flavour customisation with spices.
Additionally, eggs are a convenient and healthy way to obtain protein on a vegetarian keto diet. They are also a good source of fat and have negligible amounts of carbohydrates. When it comes to fruits, berries like strawberries, raspberries, and blackberries are lower in carbs due to their high fibre content, but other fruits like blueberries should be avoided as they can quickly deplete your daily carb allowance. It is also crucial to avoid beans, legumes, grains, and most fruits and potatoes, as these are high in carbs and can hinder ketosis.
Certain dairy products can also be incorporated into a vegetarian keto diet. Full-fat, non-sugared Greek yoghurt provides protein and good fats, and cheese is a key component, with harder cheeses being the best low-carb options. Peanut or almond butter is another excellent source of protein, but it is important to choose a low-carb variety. Brussels sprouts are also nutrient-rich and low in carbs, offering versatility in preparation.
While the keto diet has been associated with weight loss, it is important to be cautious due to the potential for nutritional deficiencies. Vegetarians are already at risk of deficiencies in vitamin B12, vitamin D, zinc, iron, calcium, omega-3 fatty acids, and protein, and the keto diet's restrictions may exacerbate these deficiencies. Therefore, it is recommended to consult a registered dietitian before starting the keto diet to ensure adequate nutrition and supplement where needed.

Vegetarians can do keto, but it's restrictive
The ketogenic diet is a high-fat, low-carb diet that has become very popular in recent years. Although it usually contains animal products like meat, fish, and poultry, it is possible to adapt it to fit a vegetarian diet. The vegetarian keto diet combines aspects of vegetarianism and keto dieting.
Vegetarians can do keto, but it is restrictive. The standard keto diet uses these macros for daily calories: 70% fats, 25% protein, and 5% carbs. This means that vegetarians doing keto will have to cut out many protein sources such as grains and legumes, which are typically used in vegetarian diets. It is important to prioritize protein in your vegetable choices without choosing veggies with a high carb count. For example, spinach has only 1g of carbs per 100g serving but is packed with protein. Tofu and tempeh can also be included in a vegetarian keto diet, but it is important to ensure they are not varieties high in carbs.
There are some other foods that vegetarians doing keto will have to avoid. These include beans and lentils (aka legumes), grains, most fruits, and all varieties of potatoes. These foods are nutritious but are high in carbs, which the keto diet strictly limits. It is also important to note that the keto diet can be deficient in vitamin B12, vitamin D, zinc, iron, calcium, omega-3 fatty acids, and protein. Therefore, it may be worth speaking to a registered dietician before attempting it.
Some foods that can be included in a vegetarian keto diet are eggs, which provide a good dose of fat and practically no carbs, and berries such as strawberries, raspberries, and blackberries, which are lower in carbs because they are packed with fiber. Certain dairy products such as Greek yogurt and cheese can also be included, as well as nuts and seeds. Non-starchy vegetables such as leafy greens, Brussels sprouts, courgette, broccoli, cauliflower, peppers, and mushrooms can be eaten, as well as vegan full-fat 'dairy' products such as coconut yogurt, vegan butter, and cashew cheese.

Plan meals carefully to avoid nutritional deficiencies
The ketogenic diet is a high-fat, low-carb diet that has become very popular in recent years. It usually contains animal products like meat, fish, and poultry, but it can be adapted to fit a vegetarian diet. The vegetarian keto diet combines aspects of vegetarianism and keto dieting.
Vegetarian keto is a restrictive diet that requires careful planning to avoid nutritional deficiencies. It is important to incorporate high-fat, low-carb, protein-rich foods into your diet. Here are some tips to help you plan your meals and avoid nutritional deficiencies:
- Include protein-packed vegetables: Prioritize protein-rich vegetables such as spinach, which has a low carb count. Tofu and tempeh are also excellent sources of protein and can be prepared in a variety of ways.
- Choose the right dairy products: Certain nutrient-dense dairy products are great for a vegetarian keto diet. Full-fat, non-sugared Greek yogurt provides protein and good fats. Cheese is also a key component, especially harder cheeses to keep it low-carb. Butter from peanuts or almonds is another great option, as it is packed with protein.
- Select the right fruits: While most fruits are too high in carbs for a keto diet, berries like strawberries, raspberries, and blackberries are lower in carbs due to their high fiber content.
- Avoid high-carb foods: Stay away from potatoes, grains, legumes (beans and lentils), and most fruits, as these are high in carbs and not allowed on the keto diet.
- Supplement with plant-based alternatives: To avoid nutritional deficiencies, consider plant-based alternatives like coconut products (full-fat coconut milk, coconut cream), non-starchy vegetables (leafy greens, broccoli, cauliflower), and vegan full-fat 'dairy' products (coconut yogurt, vegan butter, cashew cheese).
- Gradually reduce carb intake: Instead of going straight to a full-blown vegetarian keto diet, reduce your carb intake gradually. This will help your body adjust and reduce the risk of shocking your system.
- Seek professional guidance: Consult a qualified registered dietitian who can help you choose the right foods and ensure you are supplementing your diet where needed.
By carefully planning your meals and incorporating a variety of protein-rich and high-fat, low-carb foods, you can follow a vegetarian keto diet while avoiding nutritional deficiencies.

Prioritise protein and veggies without high carbs
A ketogenic diet is typically high in fat and ultra-low in carbs, and it can be challenging to adapt it to a vegetarian diet, as many vegetarian staples are high in carbohydrates. However, it is possible to do a vegetarian keto diet by prioritising protein and veggies without high carbs. Here are some tips and food choices to consider:
Vegetables
When following a vegetarian keto diet, it is essential to choose vegetables wisely. Some vegetables, like potatoes, are packed with nutrients but have a high carb count, making them unsuitable for a ketogenic diet. Instead, opt for veggies that are low in carbs and high in protein, such as spinach. With only 1g of carbs per 100g serving, spinach is an excellent choice for getting your daily dose of greens while staying within the keto guidelines. Other low-carb veggie options include cauliflower, zucchini, Swiss chard, mushrooms, asparagus, celery, bok choy, broccoli, kale, Brussels sprouts, and various types of lettuce.
Proteins
Getting enough protein is crucial on a vegetarian keto diet. Tofu and tempeh are excellent plant-based protein sources that can be prepared in a variety of ways. Just be sure to choose varieties that are not high in carbs. Eggs are another great option, as they provide a complete protein profile, healthy fats, and minimal carbs. If you consume dairy, Greek yogurt and cottage cheese are good choices, but opt for full-fat, plain, and non-sugared varieties to avoid unnecessary carbs. Hard cheeses, such as cheddar and parmesan, are also suitable, as they are lower in carbs than soft cheeses. Additionally, peanut or almond butter is a tasty way to add protein and healthy fats to your diet, with 7-8 grams of protein and 4 grams of net carbs per 2 tablespoons.
Fats
Fats are an essential component of a ketogenic diet, and they become even more critical when following a vegetarian keto plan, as they help compensate for the absence of animal-based fats. Avocado and its oil, coconut and its oil (avoid sweetened varieties), olives and their oil, and nuts and seeds are all excellent sources of healthy fats that can enhance your meals and snacks. Additionally, butter made from peanuts or almonds can provide both protein and healthy fats.
Planning and Considerations
Combining a vegetarian and ketogenic diet requires careful planning and consideration. It is essential to monitor your macronutrient intake, ensuring you stay within the keto guidelines for carbs, protein, and fat. Additionally, be mindful of your nutrient intake, as vegetarians can be at risk of falling short on specific nutrients like vitamins B12 and D, iron, zinc, calcium, and omega-3s. You may need to consider supplements or fortified foods to ensure you meet your nutritional needs.

Include eggs, berries, Greek yoghurt, and cheese
It is possible to be vegetarian and follow a keto diet, which is a high-fat, low-carb eating plan. The keto diet usually contains animal products, but it can be adapted to fit a vegetarian diet.
Eggs are a great source of protein and healthy fats, and they have practically no carbs. They are a complete food for anyone on a keto diet, and they promote feelings of fullness.
Berries are another good food group to include in a keto diet. Strawberries, raspberries, and blackberries are lower in carbs because they are packed with fibre, so your net carbs are low.
Greek yoghurt is another food that can be included in a keto diet. The plain, full-fat, non-sugared varieties are best as they are higher in protein and lower in carbohydrates. Greek yoghurt is also a good source of gut-loving bacteria and has been shown to decrease appetite and promote feelings of fullness.
Cheese is a key component of the ketogenic diet. Most varieties are very low in carbs and high in fat. To keep it low-carb, opt for the harder cheeses, although some soft cheeses like brie are also acceptable.
