Meeting Protein Needs: A Guide For Keto Vegetarians

The ketogenic diet is a high-fat, low-carb approach to eating that has gained popularity in recent years. While meat is often considered a cornerstone of the keto diet, it is possible for vegetarians to adapt this way of eating to suit their needs. However, it requires careful planning to ensure nutritional requirements are met.

Vegetarians who wish to adopt a keto diet may need to be mindful of getting enough protein, as well as vitamins and minerals such as B12, vitamin D, zinc, iron, calcium, and omega-3s. This is because many vegetarian sources of protein, such as beans, legumes, and grains, are too high in carbohydrates to be considered keto-friendly.

So, what can vegetarians eat to ensure they are getting enough protein while staying in ketosis? Here are some keto-friendly, vegetarian sources of protein:

- Eggs

- Dairy products such as Greek yogurt, cottage cheese, and hard cheeses

- Nuts and seeds, including hemp seeds, almonds, macadamia nuts, walnuts, chia seeds, and flaxseeds

- Soy products such as tofu, tempeh, and edamame

- Nutritional yeast

- Spinach and other leafy greens

- Meat substitutes such as seitan, Boca burgers, and Quorn Chik'n Cutlets

Vegetarian keto is possible, but it requires planning to ensure nutritional needs are met

The ketogenic diet is a high-fat, low-carb approach to eating that has become increasingly popular. It involves sourcing 80 to 90 percent of daily calories from fat, 5 to 15 percent from protein, and 5 to 10 percent from carbs.

The standard keto diet is meat-centric, but it is possible for vegetarians to adapt the keto diet to suit their needs. However, it requires careful planning to ensure nutritional needs are met.

Vegetarians can still eat low-carb; they just need to get their protein from non-meat sources. This might include:

• Eggs
• Dairy products such as cottage cheese, Greek yoghurt, and hard cheeses
• Nuts and seeds, such as almonds, pecans, macadamia nuts, walnuts, chia seeds, and flaxseeds
• Plant-based fats such as avocado, coconut, and olives
• Tofu, tempeh, and seitan
• Low-carb vegetables such as spinach, zucchini, Swiss chard, mushrooms, asparagus, celery, bok choy, broccoli, kale, and Brussels sprouts

The main challenge of the vegetarian keto diet is that many staple vegetarian foods are high in carbs. Vegetarians often rely on beans, lentils, and whole grains for protein, but these foods are too high in carbs to be included in the keto diet.

Vegetarians also need to be mindful of getting enough key nutrients such as vitamins B12 and D, iron, zinc, calcium, and omega-3s. Excluding even more food groups on the keto diet can make it harder to meet these nutritional needs.

The amount of protein needed on the keto diet varies depending on the individual, but it is generally recommended that most people aim for 1.2 to 2.0 grams of protein per kilo of body weight. This usually works out to at least 70 grams of protein per day.

The main risk of the vegetarian keto diet is nutritional deficiency. Vegetarians are already at risk of being deficient in certain nutrients, and the keto diet's restrictions can further increase this risk.

Vegetarians on the keto diet should be mindful of the nutrients they might be deficient in and try to eat foods that are rich in these nutrients. For example, they could eat:

• Tuna for vitamin B12
• Eggs for vitamin D
• Leafy greens like kale for calcium

They could also consider taking supplements to ensure they are getting enough of the required nutrients.

The vegetarian keto diet combines two restrictive diets, which can make it challenging to stick to. It also requires careful planning to ensure nutritional needs are met.

However, for vegetarians who want to try the keto diet, it is possible to do so in a healthy way. It is recommended that they approach the diet carefully, ideally with the guidance of a qualified dietitian, and reduce their carb intake gradually rather than going fully into ketosis overnight.

Vegetarians may need to supplement their diet with vitamins B12 and D, iron, zinc, calcium, and omega-3s

Vegetarians who follow a keto diet may need to be mindful of their nutrient intake to avoid deficiencies. While a keto diet typically includes animal products, it is possible to adapt it to suit a vegetarian diet. However, this may require careful planning to ensure you are meeting your nutritional needs.

Vitamin B12

Vitamin B12 is mainly found in animal products such as eggs, liver, fish, poultry, and dairy. Vegetarians may need to include eggs and dairy in their diet or consider taking a vitamin B12 supplement.

Vitamin D

Vitamin D is essential for maintaining bone and muscle health, and it also supports the immune system. While the keto diet does not necessarily increase the risk of vitamin D deficiency, it is still a good idea to consider supplementation as deficiency is common. Sun exposure is also a natural way to boost vitamin D levels.

Iron

Iron is crucial for maintaining energy levels and preventing anaemia. As meat is a significant source of iron, vegetarians on a keto diet may need to focus on plant-based sources like spinach, zucchini, avocado, Brussels sprouts, and cauliflower.

Zinc

Zinc is essential for wound healing, protein synthesis, immune function, and glucose metabolism. While meat is a good source of zinc, vegetarians can obtain it from nuts, seeds, and soy products like tofu, tempeh, and edamame.

Calcium

Calcium is necessary for maintaining bone health, regulating blood pressure, and supporting nerve function. Dairy products like cheese and yogurt are excellent sources of calcium for vegetarians on a keto diet.

Omega-3s

Omega-3 fatty acids are important for brain and heart health and can be found in plant-based sources like nuts and seeds. However, vegetarians on a keto diet may need to consider an omega-3 supplement, especially if they do not regularly consume fatty fish like sardines, salmon, trout, or mackerel.

Vegetarian keto-friendly protein sources include eggs, dairy, and plant-based sources like tofu, tempeh, and seitan

Eggs are a prized source of protein for vegetarians, and it's easy to see why. A single egg yolk has 4.5g of fat, 0.5g of carbs, and 2.5g of protein, while the egg white has 0g of fat, 0g of carbs, and 4g of protein. This makes eggs a great complete protein source. They are also rich in essential amino acids and B vitamins, which help support a healthy metabolism.

Dairy is another great source of protein for vegetarians on keto. Dairy options include full-fat plain yoghurt and cottage cheese, hard cheeses like cheddar, gouda, provolone, and Swiss, and soft cheeses like brie, camembert, feta, and blue cheese.

Plant-based proteins include tofu, tempeh, and seitan. Tofu is made from soybeans, which are considered a whole source of protein, providing the body with all the essential amino acids it needs. Tempeh is also made from soybeans and is a good source of probiotics, B vitamins, and minerals like magnesium and phosphorus. Seitan, also known as wheat meat or wheat gluten, is one of the richest plant protein sources available, with about 25g of protein per 3.5 ounces.

Other vegetarian keto-friendly protein sources include nuts and seeds, nutritional yeast, and spinach.

Vegetarians should avoid popular protein sources like beans, legumes, and grains, which are high in carbs

Vegetarians often rely on beans, legumes, and grains for protein. However, these foods are high in carbohydrates, which are restricted on a keto diet. On keto, it is recommended to limit net carb intake to 20 grams per day to stay in ketosis. This means avoiding popular vegetarian protein sources such as quinoa, buckwheat, legumes, and pulses.

Instead, vegetarians on keto should focus on low-carb, high-protein foods such as eggs, dairy, nuts, seeds, and soy products. Eggs, in particular, are a great source of complete protein and are rich in essential amino acids and B vitamins. Dairy products like cottage cheese and hard cheeses also provide a good amount of protein. Nuts and seeds, such as almonds, macadamia nuts, and chia seeds, are high in fat, low in carbs, and typically full of fiber.

Soy products like tofu, tempeh, and edamame are also excellent sources of protein on a vegetarian keto diet. While whole soybeans are a great option, processed soy isolates in meat substitutes may contain added sugars or unexpected carbs, so it is important to read labels carefully.

In addition to these protein sources, vegetarians on keto can include plenty of low-carb vegetables, healthy oils, and spices to add variety and ensure they are meeting their nutritional needs.

Vegetarians can get healthy fats from avocados, coconut oil, and vegetable/seed oils

Avocados are an excellent source of healthy fats for vegetarians, providing both mono- and polyunsaturated fats, which are beneficial for heart health. They are also rich in fat-soluble vitamins A, D, E, and K. In addition, avocados are a good source of potassium, magnesium, and fibre.

Coconut oil is another healthy fat option for vegetarians. While it is high in saturated fat, studies have shown that consuming foods high in saturated fat, such as coconut oil, does not raise the risk of heart disease or other health problems.

When it comes to vegetable and seed oils, it is best to choose options that are less processed and closer to their natural source. Some healthy options include olive oil, rapeseed oil, sunflower oil, corn oil, sesame oil, flaxseed oil, and hempseed oil. These oils provide essential fatty acids and can help improve heart health.

It is important for vegetarians to ensure they are getting enough healthy fats in their diet. These fats provide essential nutrients and can help with satiety, keeping them feeling fuller for longer. By including a variety of these healthy fat sources in their meals and snacks, vegetarians can meet their fat requirements and support their overall health.
