Vegan Ketogenic Diet: Is It Feasible?

The ketogenic (keto) diet is a low-carb, high-fat regimen that aims to change the way the body uses energy. While the traditional keto diet is based on the heavy consumption of animal fats, it is possible for vegans to follow a keto diet. A vegan keto diet is a low-carb, high-fat, high-protein diet that excludes all meat and dairy products. This diet requires careful planning to ensure nutritional needs are met, and there are potential risks associated with the diet if it is followed incorrectly. However, a vegan keto diet offers benefits such as weight loss, improved blood sugar control, and reduced risk of chronic diseases.

Possible health benefits of a vegan ketogenic diet

A vegan ketogenic diet is a plant-based version of the popular ketogenic diet. It is a very low-carbohydrate diet, where people get most of their energy from fats and protein. It is challenging for vegans to follow a keto diet because vegan diets are usually high in carbohydrates. However, with careful planning, it is possible.

Weight loss

The main benefit of the keto diet appears to be rapid weight loss. A 2012 study involving children and adolescents with obesity found that participants following a ketogenic diet lost significantly more weight and fat mass than those on a low-calorie diet. A review of 12 studies found that over 18 weeks, people who followed vegan diets lost an average of 5.5 pounds more than participants on non-vegetarian diets.

Type 2 diabetes

A vegan keto diet may also help with type 2 diabetes. A 2014 study of more than 96,000 people indicated that vegans have a 47-78% lower risk of type 2 diabetes. A 2014 randomised controlled trial found that those following a low-carbohydrate vegan diet experienced more significant weight loss and reductions in low-density lipoprotein (LDL) cholesterol, a risk factor for heart disease.

Heart disease

Both vegan and ketogenic diets have been linked to a reduced risk of heart disease. A systematic review suggests that a low-carbohydrate diet, such as the keto diet, may reduce some of the major risk factors for heart disease.

Cancer

A vegan diet has been linked to a reduced risk of developing certain types of cancer. A 2014 study of more than 96,000 people indicated that vegans have a 14% lower risk of developing cancer.

Other potential health benefits

A vegan keto diet may also provide other health benefits, such as improved blood lipid profiles, better blood sugar control, and reduced inflammation. However, more research is needed to determine the specific effects of a vegan keto diet on health outcomes.

Possible health risks of a vegan ketogenic diet

The vegan ketogenic diet has become increasingly popular due to its reputation as a fast way to lose weight and improve overall health. However, there are several potential health risks associated with this diet that should be carefully considered before starting it.

One of the main risks is nutritional deficiency. Many of the foods restricted on the keto diet are rich sources of essential vitamins and minerals. For example, vitamin B12, vitamin D, vitamin K2, zinc, omega-3 fats, iron, and calcium are commonly lacking in vegan diets, and the keto diet's restrictions may exacerbate these deficiencies. Additionally, the vegan keto diet may not provide enough protein, which is necessary for building bones, muscles, and skin. This could potentially lead to muscle loss.

Carbohydrates are an essential part of a healthy diet, providing the body with energy and nutrition. They are the body's preferred source of energy and play a role in maintaining healthy blood sugar levels, regulating appetite, and aiding digestion. Carbohydrates are also important sources of dietary fiber, which helps reduce cholesterol and promote regular bowel movements. A vegan keto diet is extremely low in carbohydrates, and this deficiency can cause a drop in energy levels, difficulty concentrating, and strained bowel movements.

Furthermore, there is some evidence suggesting that the high-fat content of the vegan keto diet may increase the risk of heart disease. The keto diet has been linked to higher levels of "bad" LDL cholesterol and increased triglycerides, both of which are risk factors for heart disease.

The vegan keto diet is also quite restrictive, eliminating many food groups and requiring careful planning to ensure adequate nutrition. This lack of variety and strict restrictions can make it challenging to stick to the diet in the long term.

Lastly, the keto diet in general, including the vegan keto variation, can cause side effects during the transition period, often referred to as the "keto flu." Symptoms may include an upset stomach, dizziness, decreased energy, and mood swings.

It is important to consult with a healthcare professional before starting any vegan keto diet to ensure that it is safe and appropriate for your individual needs and health status.

Vegan ketogenic diet meal ideas

A vegan ketogenic diet is a challenging endeavour, but it is possible. The ketogenic diet is based on a high fat-to-carb macronutrient ratio, while a vegan diet is typically the opposite, being high in carbs. However, with some careful planning and preparation, it is possible to enjoy the benefits of both.

How to get enough protein on a vegan ketogenic diet

A ketogenic diet is high in fat, low in carbohydrates, and moderate in protein. While it may seem challenging to get enough protein on a vegan ketogenic diet, it is possible. Here are some tips to ensure you're getting sufficient protein while following this diet:

• Determine your protein needs: The amount of protein you need depends on your lean muscle mass, activity levels, and fitness goals. Use a fitness app or keto calculator to estimate your daily protein requirement. Aim for a minimum of around 70 grams of protein per day to meet basic needs and account for the lower bioavailability of plant protein sources.
• Choose keto-friendly whole food vegan protein sources: Include foods like hemp seeds, nutritional yeast, firm tofu, tempeh, seitan, soybeans, peas, spinach, almonds, sunflower seeds, pumpkin seeds, peanut butter, and lupins (lupini beans) in your diet. These foods provide a good amount of protein while being low in net carbs.
• Combine different plant protein sources: Plant-based sources of protein often lack complete amino acid profiles. To ensure you're getting a full spectrum of amino acids, combine different plant protein sources in your meals as much as possible.
• Consider soy products with caution: Soy is a common plant-based protein source, but its effects on health depend on whether it is processed (e.g., tofu, soy isolate, soy milk) or fermented (e.g., tempeh, miso, soy sauce). Opt for fermented sources and consume soy sparingly to avoid potential negative effects on hormones.
• Supplement with vegan protein powders: If you're struggling to meet your protein goals, consider adding vegan protein powders to your diet. Options like hemp, rice, and pea protein powders offer antioxidants, weight-loss support, and near-complete amino acid profiles.
• Go for gluten-free and soy-free options: If you're gluten-intolerant or avoiding soy, there are still plenty of protein sources available. For example, hemp seeds, nutritional yeast, almonds, sunflower seeds, pumpkin seeds, and lupins are all gluten-free and soy-free.
• Don't forget veggies: Vegetables like greens, broccoli, and mushrooms provide a decent amount of protein while being low in carbohydrates.
• Monitor your lysine intake: Lysine is an essential amino acid commonly found in beans. If you're not eating soy, ensure you're getting enough lysine from other beans like peas or lupins, or consider using a vegan protein powder that includes lysine.

Here's a sample one-day meal plan to give you an idea:

• Breakfast: 2 vegan keto bagels with 1 oz nut-based cream cheese
• Lunch: Zucchini Pad Thai
• Dinner: Vegan keto Kathmandu curry with 1 cup cooked spinach, 2 tbsp nutritional yeast, and 1 tsp olive oil
• Dessert: Almond Butter & Jelly chia pudding

Remember, this is just an example, and your protein needs may vary. Adjust your meals according to your specific requirements and preferences.

How to get enough vitamins and minerals on a vegan ketogenic diet

A vegan ketogenic diet is a challenging combination of two restrictive diets. The ketogenic diet is high in fat, low in carbohydrates, and moderate in protein, while veganism excludes all animal products.

The challenge of getting enough vitamins and minerals on a vegan ketogenic diet is due to the limited food options available. However, it is possible to ensure adequate nutrient intake with careful planning and supplementation. Here are some tips to get enough vitamins and minerals on a vegan ketogenic diet:

• Vitamins B2, B3, B12, D, iodine, zinc, and calcium are among the nutrients that vegan diets often lack. Vitamin B12, in particular, is not naturally found in plant foods, so vegans should consume B12-fortified foods or take supplements. Some B12-fortified foods include vegan meat substitutes, plant milk, and breakfast cereals.
• Vitamin D can be obtained through safe sun exposure. Additionally, some mushrooms, when exposed to UV light, become a good source of vitamin D.
• Vitamin K can be found in high amounts in dark, leafy greens such as spinach, turnip greens, beet greens, collard greens, kale, and broccoli.
• Iron can be obtained from morel mushrooms, lentils, amaranth, teff, lima beans, sesame seeds, edamame, tofu, and oat bran. Consuming vitamin C-rich foods alongside plant sources of iron can increase its absorption.
• Zinc can be obtained from hemp seeds, oats, teff, lentils, pumpkin seeds, and tofu.
• Omega-3 fatty acids are commonly obtained from fish oil, but vegans can get them from hemp seeds, which also provide protein.
• Protein can be challenging to obtain on a vegan ketogenic diet. Soy is a common source of plant-based protein and is known for its potential health benefits, including lowering LDL cholesterol and reducing blood pressure. Tofu and tempeh are good sources of soy protein, offering all nine essential amino acids. However, soy products should be consumed in moderation due to the presence of anti-nutrients and potential negative effects on estrogen levels. Other plant-based protein sources include hemp seeds, nuts, and supplemental vegan protein powders such as soy, hemp, rice, and pea protein.
• Fats are an essential part of the ketogenic diet, and there are several vegan sources of healthy fats, including coconut products (oil, milk, cream, and yogurt), olive oil, nut oils, MCT oil, avocado oil, nuts (especially Brazil nuts and walnuts), and seeds (such as hemp seeds, chia seeds, and pumpkin seeds). Avocados and nut butter are also good sources of healthy fats.
• Low-carb vegetables suitable for a vegan ketogenic diet include leafy greens (such as kale, spinach, and Brussels sprouts), zucchini, broccoli, cauliflower, peppers, and mushrooms.
• Low-carb fruits that can be included in moderation are avocados, berries (such as blueberries, blackberries, raspberries, and strawberries), and coconut.
