Vegetarian Keto: Understanding The Basics Of This Diet

The ketogenic diet is a high-fat, low-carb diet that has become increasingly popular in recent years. While it usually contains animal products, it is possible to adapt it to fit a vegetarian diet. The vegetarian keto diet is an eating plan that combines aspects of vegetarianism and keto dieting, eliminating meat and fish and relying on other healthy fats such as coconut oil, eggs, avocados, nuts, and seeds. This diet requires careful planning to ensure nutritional needs are met and can be challenging to stick to due to its restrictive nature.

Characteristics of a Vegetarian Keto Diet

What to eat: vegetables, fruits, nuts, seeds, dairy, eggs, and tofu

Vegetables, fruits, nuts, seeds, dairy, eggs, and tofu are all foods that can be incorporated into a vegetarian keto diet.

Vegetables that are suitable for a keto diet include cauliflower, zucchini, Swiss chard, mushrooms, asparagus, celery, spinach, bok choy, broccoli rabe, cabbage, broccoli, kale, Brussels sprouts, and lettuces (arugula, green and red leaf, endive, and romaine). These vegetables are low in carbohydrates, and some, like spinach, are also high in calcium and iron.

Fruits that are suitable for a keto diet include avocados, strawberries, raspberries, blackberries, lemons, tomatoes, peaches, cantaloupe, and star fruit. These fruits are low in net carbs and high in fiber, vitamins, and minerals.

Nuts that are suitable for a keto diet include pecans, macadamias, pili nuts, hazelnuts, walnuts, peanuts, almonds, pistachios, and pine nuts. When choosing nuts, it is important to select those with the lowest carb content and to avoid those treated with sugar or other glazes. Additionally, it is important not to overeat nuts, as they are high in calories and can hinder weight loss.

Seeds that are suitable for a keto diet include chia seeds, flax seeds, hemp seeds, pumpkin seeds, safflower seeds, sesame seeds, and sunflower seeds. These seeds are high in fat and protein, and the carbohydrates they contain are offset by their dietary fiber content, resulting in optimal net carbs.

Dairy products that are suitable for a keto diet include butter, hard and soft cheeses, Greek yogurt, cottage cheese, and sour cream. When choosing dairy, it is important to select products with minimal carbohydrates and no added sugar. Dairy products can provide valuable protein, fat, potassium, and calcium, but they also contain sugar in the form of lactose, which can push the body out of ketosis.

Eggs are an excellent choice for a keto diet, as they are high in protein and fat and have minimal carbohydrates. They are a convenient and healthy source of nutrients such as vitamins, minerals, and micronutrients like choline and selenium. It is generally recommended to consume up to 6 or 7 eggs daily on a keto diet, but this can vary depending on individual dietary needs and goals.

Tofu is a low-carb, vegetarian source of protein that can be included in a keto diet. However, it is derived from soybeans, which are high in omega-6 fatty acids, which may cause inflammation. It is important to balance tofu consumption with other fatty foods like fish to maintain a healthy ratio of omega-3 to omega-6 fatty acids.

What not to eat: meat, legumes, grains, and starchy vegetables

A vegetarian keto diet is a high-fat, low-carb eating pattern that eliminates meat and seafood. It is possible to adapt the traditional keto diet to fit a vegetarian lifestyle, but it requires careful planning to ensure you are meeting your nutritional needs.

Meat

All meat should be avoided on a vegetarian keto diet. This includes:

• Beef
• Pork
• Lamb
• Goat
• Veal
• Poultry (chicken, turkey, duck, goose)

Legumes

Legumes are also not allowed on a vegetarian keto diet. This includes:

• Beans
• Peas
• Lentils
• Chickpeas

Grains

Grains are high in carbs and should be limited or avoided on a vegetarian keto diet. These include:

• Bread
• Rice
• Quinoa
• Oats
• Millet
• Rye
• Barley
• Buckwheat
• Pasta

Starchy Vegetables

Starchy vegetables are also high in carbs and should be limited. Some starchy vegetables to avoid or limit are:

• Potatoes
• Yams
• Beets
• Parsnips
• Carrots
• Sweet potatoes

Pros: weight loss, blood sugar control, and protection against chronic illnesses

The vegetarian keto diet is a high-fat, low-carb eating plan that eliminates meat and fish. It is challenging to follow because it combines two restrictive diets. However, it has several benefits, including weight loss, blood sugar control, and protection against chronic illnesses.

Weight Loss

The vegetarian keto diet has been linked to weight loss in several studies. One large review found that those on a vegetarian diet lost an average of 4.5 pounds (2 kg) more than non-vegetarians over 18 weeks. Another 6-month study of 83 people with obesity found that a keto diet resulted in an average weight loss of 31 pounds (14 kg). The high amount of healthy fats in this diet may also reduce hunger and appetite, leading to greater weight loss.

Blood Sugar Control

Vegetarian and keto diets have been shown to support blood sugar control. A review of six studies linked vegetarian diets to a significant reduction in HbA1c, a marker of long-term blood sugar control. Additionally, a 5-year study of 2,918 people found that switching to a vegetarian diet reduced diabetes risk by 53%. The keto diet has also been found to improve the body's blood sugar regulation and increase its sensitivity to insulin.

Protection Against Chronic Illnesses

Vegetarian diets have been associated with a reduced risk of several chronic conditions, including cancer, heart disease, and other critical health problems like hypertension and diabetes. The keto diet has also been studied for its effects on disease prevention, with some research suggesting it may safeguard brain health and help treat Parkinson's and Alzheimer's diseases.

Cons: nutritional deficiencies, flu-like symptoms, and unsuitability for certain people

Combining vegetarian and ketogenic diets can be challenging due to the restrictive nature of both eating patterns. This combination may lead to nutritional deficiencies, flu-like symptoms, and may not be suitable for certain individuals.

Vegetarian diets can be low in essential nutrients, such as vitamins B12 and D, iron, zinc, calcium, omega-3s, and protein. The keto diet is even more restrictive as it limits several nutrient-dense food groups, including fruits, legumes, and whole grains. As a result, the vegetarian keto diet may further increase the risk of nutritional deficiencies. Careful planning and monitoring of nutrient intake are necessary to ensure adequate nutrition.

Transitioning to a vegetarian keto diet can trigger flu-like symptoms, commonly known as the "keto flu." These side effects are caused by the body's adjustment to a significant reduction in carbohydrate intake. Symptoms may include fatigue, muscle soreness, stomach pain, intestinal pain, and cravings. These symptoms typically last a few days to several weeks and can be mitigated by staying hydrated, replacing electrolytes, and getting adequate rest.

The highly restrictive nature of the vegetarian keto diet may not be suitable for everyone. It should be avoided by children, pregnant or breastfeeding women, athletes, individuals with a history of eating disorders, and people with type 1 diabetes. Additionally, those with underlying health conditions or taking medications should consult a healthcare practitioner before starting this diet.

Tips: eat eggs, dairy, and low-carb vegetables with healthy fats

Eggs, dairy, and low-carb vegetables with healthy fats are a great way to get started on a vegetarian keto diet.

Eggs are a fantastic source of protein and fat, with around 6 grams of protein and less than 1 gram of carbs per large egg. They're also said to trigger hormones that increase feelings of fullness. Enjoy them scrambled, fried, or boiled.

For dairy, opt for full-fat plain yogurt, cottage cheese, hard cheeses, and butter. These are high in fat and low in carbs, making them perfect for a keto diet. Just be mindful of flavoured and sweetened varieties, as these can be high in sugar.

When it comes to low-carb vegetables, think cauliflower, zucchini, spinach, broccoli, kale, Swiss chard, mushrooms, asparagus, celery, bok choy, Brussels sprouts, and lettuce. These veggies are packed with nutrients and can be prepared in a variety of ways to keep things interesting.

Finally, healthy fats are an essential part of the keto diet, and avocados, olives, and their oils are great choices. Avocados are high in fat and fibre, and olives contain an antioxidant that may protect your cells from damage.

Remember, the key to a successful vegetarian keto diet is careful planning and ensuring you're getting adequate nutrition.
