Getting Started With a Vegetarian Diet

A vegetarian diet is one in which no meat or seafood is consumed. Most vegetarians are lacto-ovo vegetarians and also consume eggs and dairy. But some choose to avoid eggs (lacto-vegetarians) and some choose to avoid dairy (ovo-vegetarians).

For example, some people find success by going meatless one day each week. Meatless Mondays are popular and it's easy to find online support, tips, and recipes. Once you are comfortable with a once-weekly plant-based diet, you can start to go meatless during other days of the week.

Others find it helpful to try a flexitarian diet first. A flexitarian diet is a modified vegetarian diet that allows you to eat meat on some limited occasions. Once you are comfortable with the flexitarian eating style, you can fully adopt a vegetarian diet if you choose.

Regardless of which strategy you choose, remember to give yourself time when first adopting this lifestyle. Experiment with new recipes, gather support from friends and family and take advantage of as many resources as possible to adjust to your new eating plan.

When you are making any dietary changes it's smart to check your calorie intake to make sure it is in line with your calorie needs.

Studies have shown that those who follow a vegetarian diet typically consume fewer calories than those who eat omnivore diets (diets that have no restrictions). This calorie reduction usually happens naturally because foods that are eliminated on a vegetarian diet are foods that tend to be higher in fat and calories, such as meat and (sometimes) dairy.

To make sure you are getting the right number of calories on your vegetarian diet, you can use a calorie calculator. Simply input your height, weight, and activity level and your goals regarding weight loss or weight gain. The calculator provides a personalized estimate of the number of calories you need.

Hydration Tips

You may find that staying hydrated is easier on a healthy vegetarian diet than it is on a traditional western diet because you consume more produce. Water makes up nearly 90% of the weight of many fruits and vegetables that we consume. In fact, studies have shown that increasing your fruit and vegetable intake can promote a healthy water balance in the body.

Depending on the vegetarian diet that you choose, you may need to reconsider some of your regular beverage choices. On an ovo-vegetarian diet, dairy products (including milk, cream and yogurt-based beverages) are not compliant. However, nut milks may be a suitable alternative. Most grocery stores carry milk alternatives such as soy milk, cashew milk, almond milk, coconut milk, and many others.

Changing your diet often requires you to change your grocery shopping habits. On a healthy vegetarian diet, you'll spend no time in the meat and seafood area, but much more time in the produce section. You might even consider trying a new type of market, such as a farmer's market, or health food store to get the foods you need to stay healthy.

If budget is a concern, choose seasonal fruits and vegetables. Not only does this help to keep costs down, but it's a great chance to experiment with new foods and flavors. For example, in the springtime try lychees or mangos. In the winter, try squash or sweet potatoes.

Bulk Foods

When buying grains, nuts, or seeds, consider buying in bulk. You can save money by purchasing only the amount that you need. Also, these foods are usually cheaper because packaging costs are eliminated. Look for these items in the bulk section:

• Flax, chia, hemp, sesame, or sunflower seeds
• Quinoa, farro, bulgur, barley, oats, and other whole grains
• Almonds, cashews, pistachios, and other tree nuts
• Peanuts, pulses, and other legumes
• Dried fruit such as calcium-rich dried figs

Lentils, chickpeas, and beans are good sources of iron. You can find these in the bulk section or in the canned goods aisle. Some whole grains such as amaranth and oats also provide iron, so you'll want to stock up on these ingredients so you have them on hand for recipes.

You might also find nutritional yeast in the bulk section, although different stores carry it in other sections as well. Nutritional yeast can be added to your favorite recipes (such as soup or pasta dishes) and can be healthy for someone on a vegetarian diet because it provides B vitamins, especially B12 which is sometimes deficient in a vegetarian diet.

Produce Section

Choose fruits and vegetables that provide the vitamins and minerals that are likely to decrease when removing animal products from your diet. Choose calcium-rich fruits and veggies such as kale, figs, broccoli, broccoli rabe, or okra. And protein-rich produce, like spinach, alfalfa sprouts, or asparagus will help you maintain muscle mass.

Mushrooms are another food to stock up on in the produce aisle. If you are having a hard time removing beef from your meals, mushrooms provide a savory, meaty alternative.

Other nutritious fruits and vegetables to consider include:

• Sweet potatoes
• Mustard or collard greens
• Arugula, Swiss chard, and other leafy greens
• Bok choy
• Cabbage
• Eggplant
• Spaghetti squash
• Oranges
• Apples
• Avocado
• Tomato
• Fiber-rich berries like raspberries

You may also want to explore the fresh herb section of the produce department. Learning to flavor your food with basil, rosemary, dill, or other fresh herbs can help you to reduce your dependence on the salt shaker. Fresh ginger is also found in the produce section. Use it in veggie stir fry recipes, tea, or salad dressings.

Frozen Foods

You'll find a wide array of vegetarian microwavable meals, meat substitutes, and other quick fast-food style offerings in the freezer section. You'll also find many frozen treats that are made without dairy for those who follow an ovo-vegetarian diet. For example, coconut or nut-based ice cream can satisfy your sweet tooth and may even provide a little boost of protein.

Keep in mind that while these convenience foods are compliant on your new vegetarian eating plan, they don't always provide good nutrition. Some contain excess sodium, sugar, and other additives. They may be helpful to have on hand, but for optimal nutrition, consider stocking up on less processed frozen foods including:

• Frozen soybeans (edamame)
• Frozen vegetarian soups
• Frozen berries, pineapple and other fruits for smoothies and recipes
• Frozen vegetables such as Brussels sprouts, spinach, or peas
• Frozen whole-grain waffles, bread, or other baked goods

Buying frozen produce can help cut costs at the market. Frozen fruits and vegetables are just as healthy as their fresh counterparts when they are packaged without additives and they stay fresh much longer.

Cereals, Canned, and Dry Goods

In the middle aisles of the grocery store, you'll find many nutritious vegetarian offerings, like beans and fortified cereal. When buying legumes, consider purchasing the dried variety rather than canned goods as some canned goods are high in salt.

• White beans
• Kidney beans
• Black beans
• Whole-grain cereal
• Dried herbs and spices
• Rolled oats
• Tahini
• Plant-based oils
• Whole-grain crackers
• Vegetarian soups such as bean soup or tomato soup
• Protein powder made with soy, rice, or pea protein

When buying cereal, try to look for brands that are fortified with vitamin B12. This nutrient is often lacking in vegetarian diets because it is most commonly found in meat and seafood. But you can get your recommended daily intake by consuming foods like cereal that are fortified with it.

You might also want to look for Ezekial bread in the dry goods area (although sometimes it is sold in the freezer section). This bread is popular because it is made with sprouted grains and lentils. Each slice provides four grams of protein and other nutrients including B vitamins, zinc, calcium, and iron–nutrients particularly important for those who follow a vegetarian diet.

Refrigerated Section

If you are a lacto-ovo vegetarian, you'll stock up on dairy products and eggs in this section. Foods like Greek yogurt, cheese, milk, and cottage cheese help boost your calcium and protein intake.

If you don't consume dairy, look for these alternative foods in the refrigerated section:

• Soy milk
• Soy cheese
• Coconut milk
• Plant-based yogurt (such as coconut yogurt) 
• Orange juice, fortified with calcium
• Tempeh or tofu
• Hummus
• Kombucha
• Fermented foods like sauerkraut or miso paste

When choosing soy milk or other milk alternatives, consider looking for a product that is fortified with calcium or other vitamins and minerals, such as B12.

Because plant-based diets have blossomed in popularity, there is a wealth of resources that can help you learn to cook vegetarian dishes. Making your own meals at home gives you control over the ingredients, so you can include foods that boost nutrition and limit salt, sugar, and saturated fats.

Breakfast

Start your day with hearty breakfast foods that provide fiber and protein.

• Whole Grain Mini Berry Crisps
• California Summer Vegetable Omelet
• Maple Pumpkin Pie Buckwheat Groats

Lunch and Dinner

Replace meat-based meals, like sandwiches, steak, or burgers with filling savory dishes made to satisfy.

• Kale and Lentil Stuffed Sweet Potato
• Indian Potato and Lentil Stew
• Vegetarian Vegetable, Bean, and Cheese Enchiladas

Snacks

Boost your protein and fiber intake with healthy snacks.

• Cumin-Lime Roasted Chickpeas
• Peppery Parmesan Oat Crackers
• Healthy, Easy Spicy Edamame Dip

Dessert

Indulge and enjoy sweet treats with or without dairy

• Frozen Cappuccino Granita Dessert
• Pumpkin Cheesecake Mousse
• Mocha Dusted Almonds

Cooking certain foods in advance will help you to stay healthy and satisfied on a vegetarian diet. Having nutritious plant-based meals and snacks ready to go will help you to rely less on processed microwavable foods.

• Beans and lentils can be soaked and cooked ahead of time. Prepare a batch or two once each week, then keep them refrigerated so that you can grab a handful to toss on salads on top of grains, or into soups or stews.
• If you soak oats overnight, they take less time to prepare in the morning. Simply combine oats with your favorite add-ins (like fruit, seeds, or nuts), cover, and place in the refrigerator.
• Keep single-serving containers of chopped fruits and vegetables on the front shelves of your refrigerator so they are the first thing you see when you're hungry and starting to graze.
• Keep single-serving packets of peanut butter (either store-bought or make your own) in your pantry. Pack them in your day bag or briefcase so that you have an easy-to-eat snack during the day.

You might also want to learn to cook with tofu when you shift to a vegetarian diet. The food is not typically consumed by those who eat a standard western diet, but it is a staple in vegetarian and vegan kitchens.

Tofu can be purchased in different forms: firm, soft, or silken. The different consistencies make it a versatile addition to your recipes. Silken tofu can easily be added to smoothies and pudding. Stir fry or grill firm tofu as a meat alternative. Soft tofu can be added to soups or batters.

A Word From Verywell

Adopting a vegetarian diet can be challenging at first, so it's important to be patient with yourself as you remove meat and potentially dairy products from your meal plan. Take advantage of online resources, cookbooks, vegetarian magazines, and even the expertise of your local grocer to help make the process easier. The produce manager at your local market may be able to tell you about seasonal produce and even share recipes.

Also, remember that you have options when making the shift. Flexitarians enjoy an occasional meat or seafood meal and still gain benefits from eating primarily plant-based foods. Eventually, you're likely to find vegetarian eating can be satisfying and enjoyable. And if you make healthy vegetarian choices, you're likely to enjoy the health benefits of plant-based eating as well.
