Still, Mass is hesitant to recommend this way of eating. “I don’t see many benefits to going keto vegetarian,” she says. The major concern is nutritional deficiencies. As Medline Plus notes, vegetarians already are at risk of being deficient in vitamin B12, vitamin D, zinc, iron, calcium, omega-3 fatty acids, and protein. Keto then puts more restrictions in place, further increasing the likelihood of being deficient in some of these nutrients. For example, breakfast cereals, which are usually rich in vitamin B12, are not allowed on keto.
Eating keto foods while still enjoying your favorite dishes can be a big challenge especially if you're just starting a keto, low carb, or paleo lifestyle. Fear not! Committing to healthier eating doesn't mean that you need to miss out on an occasional chocolate chip cookie or your favorite holiday shortbread. It simply means that you need to find a new recipe!
The health benefits of vegan and vegetarian diets are well-documented; in fact, cutting meat out of your diet has been linked to many health benefits, including a reduced risk of cancer and heart disease. (5) Plus, just like regular keto, vegan keto results in some pretty impressive benefits as well, ranging from increased weight loss to improved heart health. (6)
And speaking of working out, if you’re a gym rat or avid runner, prepare for your workouts to suck for a while until your body fully adapts to the diet. If you’re cutting out carbs for the first time, your body will need two weeks or more (and sometimes months) to fully support the demands of exercise with ketones. And if you’ve been relying on animal products, you may find it difficult to recover without the full array of amino acids that every serving of animal protein provides. You’ve chosen a hard road to travel, nutritionally, but don’t lose heart. Time and persistence will force your body to accommodate just about any regimen you subject it to, and there are plenty of people whose performance has thrived on unconventional diets.
There are plenty of plant-based fat sources but in order to meet your protein needs you will need to incorporate high protein, vegan friendly foods such as nuts and seeds, tempeh, tofu, and vegan protein powder. Food companies such as Beyond Meat are now providing alternative meat products that are a great source of protein while still relatively low in carb. Unlike meat, some of these vegetable based proteins do not contain complete proteins but if you are good about eating a variety of plant-based foods you can meet all of your essential amino acids needs.
Takeaway: It’s possible to be vegan and do nutritional ketosis but you will need to do some research, planning/calculating, and self-experimentation to make sure you are meeting all of your requirements. You may also want to include a multivitamin containing vitamin B12 and a vegetarian omega-3 supplement (such as flaxseed oil or algal DHA such as ‘Neuromins’) to ensure you are meeting all of your nutrient needs!
If you’ve read through this entire guide, bravo. It’s huge, much bigger than I ever intended, actually. I’m really passionate about both vegetarianism and the ketogenic diet, so I honestly had a lot of fun producing all this information for you. I hope it was helpful, that you learned something, and that you feel better equipped to take on this mash-up diet.

Walking is great exercise for weight loss, but it seems to be even more effective when done just after eating. A 2011 Japanese study found that walking immediately after a meal was more effective for weight loss than waiting up to an hour afterwards. Subjects who went for a brisk, 30-minute walk just after lunch and dinner lost more weight than those who waited to walk. And because walking is a low impact form of exercise, it shouldn’t cause any digestive distress.

I want to be totally honest about what I experienced on a vegan keto diet so that you know what you are getting into. My intention is not to turn anyone away from the diet, just be transparent about my experience with it. I would do a lot of research before starting it so that you know what you are getting into and how to maintain it without any symptoms. Now, there's nothing wrong with training in a fed state. Any exercise burns energy, which supports your weight-loss efforts. What many people don't know, however, is that training in a fasted state offers several unique fat loss benefits.
