While it hasn’t been formally studied, “it is generally observed that, if you are keto-adapted,” says D’Agostino, “it is easy to fast for prolonged periods of time. This has practical benefits for occupations where stopping to eat would be an inconvenience—such as for military personnel—and jobs where you do not want to lose the flow of productivity.” If you do get hungry during a fast, D’Agostino recommends taking a supplement that provides ketones (known as exogenous ketones), which will help sustain ketosis and energy. “I typically take a ketone supplement late afternoon and follow up with a whole-food meal in the evening,” he says.
Plate sizes have certainly changed over the years, increasing in diameter just like our waistlines. Our great grandmother's dinner plates looked like today's salad plates. “We're all visual, and it's so much easier to eat the right portion and feel satisfied when we eat on smaller plates,” says Cheryl Harris, MPH, RD, holistic nutrition coach in Virginia. If you’re eating in a restaurant that's using plates the size of manhole covers, try ordering your own salad or appetizer and sharing a main dish. When dining out alone, ask the server to wrap half your dish in a doggy bag before it's served, and enjoy the rest on a smaller appetizer plate — you'll never know what you're missing!
I know others of you are probably like, “Finally! A keto vegan/vegetarian post is just what I’ve been waiting for!” If that’s you, I am so excited to be able to help you out. I know limited food options can lead to a bit of a monotonous and dreary existence, and can eventually result in a horrendous bout of binge eating and crushing guilt later on. My mission is to help you avoid that vicious cycle and discover the wonderful opportunities that are out there in the small, but vivacious, world of vegan and vegetarian ketogenic living!
Ketogenic diets originated in the 1920s as a treatment for epilepsy, but they’ve since been credited for promoting a number of health benefits ranging from improved insulin sensitivity to everyday mental clarity, in addition to fast weight loss. Strict ketogenic—or “keto”—dieters limit carbohydrate intake to about 5% of their daily calories while keeping protein intake at around 20%. Fats, then, make up close to 75% of their calories. (For more details on setting up various ketogenic diets, see our guide HERE.)
Most of the studies about ACV have been done on animals—or in really small groups of people, explains Eliza Whetzel-Savage, R.D., a registered dietitian at Middleburg Nutrition in New York City. “There is one study of people that showed ACV may slow digestion of food and liquid, which may help stabilize blood sugar,” she says. “But overall, there is not much science to support many of the claims.”
Still, Mass is hesitant to endorse this way of consuming. “I don’t see many blessings to going keto vegetarian,” she says. The main challenge is dietary deficiencies. As Medline Plus notes, vegetarians already are liable to being deficient in vitamin B12, vitamin D, zinc, iron, calcium, omega-3 fatty acids, and protein. Keto then puts extra regulations in vicinity, further growing the probability of being deficient in a number of those vitamins. For instance, breakfast cereals, which are commonly rich in vitamin B12, aren’t allowed on keto.

Think twice before noshing on grab-and-go items like sugary cereals and calorie-laden muffins, and aim for a high-protein first meal. Sweet foods give you a quick energy spike, but the rapid drop in blood sugar that follows will make you want to curl up under your desk for a nap. Research shows eating 45 grams of protein at breakfast is optimal to trigger satiety. Yes, bacon is protein-packed but it also comes with a lot of fat. “The quality of calories counts,” warns Vicki Shanta Retelny, a dietician and author of “Total Body Diet for Dummies.”Aim for a mix of protein, whole grains, fruits, vegetables and healthy fats to fuel your day.

By being aware of the things you might be deficient in, you could (and should) load up on foods that are rich in those nutrients, such as cheese for vitamin B12, eggs for vitamin D, and leafy greens like kale for calcium. If you are interested in trying keto without eating meat, Mass also recommends easing up on how strict of a vegetarian you are and eating fish if you don’t already since it’s a great source of omega-3s and protein.
Protein is also a big concern. “Since the keto diet is relying on protein and fat for your calorie intake, you are cutting out many of the complete proteins you would be attaining — say from legumes and grains — on a regular vegetarian diet,” Mass says. “On a keto diet, this source of complete proteins is now essentially eliminated.” Protein is important to help the body build bones, muscles, and skin, according to Medline Plus.
Fat is important on the keto diet, but especially so if you are vegan or vegetarian. “Aim to get 75 percent or more of your calories from plant-based fats like coconut oil, coconut cream/butter, MCT oil, olive oil, avocado, and—in lesser amounts—nuts and seeds,” says Dr. Axe. “Keep nut and seed consumption to about 1/4 cup per day (or two tablespoons of nut butter), since these do provide some carbs and can also be hard to digest in large amounts.” To help with absorption of minerals, he recommends soaking or sprouting nuts first.
I ate five to nine servings of fruits and vegetables a day, cut out fried foods, and switched from eating refined carbohydrates like white bread to complex carbs like whole-wheat bread. I promised myself that after one year of living healthfully, I'd treat myself to fast-food fries (an old favorite), but I couldn't finish them. Now my cholesterol is in a healthy range, and I still walk 30 to 60 minutes four or five days a week. Many might wonder how to reduce belly fat quickly at home with natural remedies
