Possible side effects of going vegan

Nutrition education

Every healthy diet needs to be well-planned. This is true for plant-based diets as well as for any other!

The American Dietetic Association states that “vegan diets are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases.”

But this is only true if you know how to cover your nutritional needs! So, you need to educate yourself.

Solution

Eat from all vegan food groups: fruits, veggies, (whole) grains, legumes, nuts and seeds. Take a B12 supplement and check our full vegan nutrition guide here. Grab our printable nutrition sheets below if you like!

Low energy

Do you feel like you’ve lost your spark or want to sleep all day? While this could have many reasons, it can be diet-related.

A vegan diet consists of many lower-calorie foods, such as fruits and veggies — it’s not uncommon for new vegans to unintentionally eat too few calories by loading up on healthy produce!

Animal-based foods are typically high in fat, low in water and devoid of fiber — all of which makes them rich in calories. These need to be replaced adequately!

Fatigue can be a sign of many things, including insufficient nutrient intake. If you cannot make out obvious reasons for being tired like too little sleep due to stress, investigate it further and seek professional help!

Solution

Low energy is usually due to eating too little. Focus on high-calorie foods, track your food intake over a few days and cover the basics like sleeping enough and reducing stress.

Weight loss

Unintended weight loss is no fun! If you notice that you cannot keep any weight on you since going vegan, remember that there are many calorie-packed foods like chips or chocolate that are vegan — so it’s not due to veganism per se.

Eating plant-based isn’t just about salads or smoothies, there are more vegan food groups to eat from!

Please consult a doctor once you’ve ensured that you eat enough throughout the day and are still losing weight!

Solution

Follow our guide on gaining weight on a vegan diet and choose from this selection of tasty high-calorie vegan meals. Don’t rely on fruits and veggies too much, have sandwiches, pasta, energy balls and more!

Weight gain

If you’ve been gaining weight since going vegan, this can be due to a couple of factors!

Perhaps you’re intrigued by all the new and exciting vegan foods like ice cream or veggie burgers.

Or you’ve read that you can eat as much as you want on a vegan diet without gaining a pound?

Unfortunately, that’s not the case. Especially if you’ve been eating refined carbs, food drenched in oil or heavy sauces, the calories can add up quickly!

Solution

Check out our plant-based weight loss guide or try these low-calorie recipes to learn how you can create delicious meals that support your weight goals.

Feeling hungry

Constantly feeling hungry and never really satisfied with their food is something new vegans may experience.

Follow a specific (restrictive) vegan diet, such as a low-carb or low-fat vegan diet can lead to decreased satiety in some people!

Jump back to the beginning of the article to learn about the nutrition basics of a plant-based diet and fill your plate with satiating starches, plant-based protein, healthy fats and veggies.

Solution

If you’re always hungry, eat more filling and fiber-rich foods! Combine them with creamy sauces and complex carbs to stay full for hours on end. Check out the links above about higher-calorie foods and meals!

Food cravings

Whenever we switch from one diet to another, we usually experience cravings. They are often just reminders of foods we were used to eating for a long time — and sometimes, we crave the foods we’re trying to avoid the most.

Make sure that you’re eating enough and covering basic nutritional needs by reading about plant-based nutrition.

You can also get in touch with your reasons for wanting to be vegan and ask yourself whether you’ve restricted your diet too much!

Nowadays, there are delicious vegan replacements for anything from pizza to donuts, ice cream, cheese and meat. Try some of them!

Solution

Understand these feelings better and know that they are only temporanry! To prevent cravings, eat enough, eat mindfully, make your food taste delicious and try vegan alternatives if you’re craving animal products.

Indigestion

Introducing new foods or eating patterns to our belly and gut bacteria can mean trouble!

From belly rumblings, gurglings or other signs of indigestion like flatulence, constipation or diarrhea, everyone reacts a bit differently.

It’s best to stay as close to your former eating patterns as possible when transitioning to a vegan diet and recreate your omnivorous or vegetarian diet in a vegan way before introducing lots of beans or broccoli!

Solution

A slow transition is key to keeping your digestion happy! Drink plenty of water as you increase the fiber in your diet, and cook your veggies and puree legumes if they are hard to digest. Read more about a low-fiber diet and bloating on a vegan diet!

Eating out

Following a fully vegan diet at home is one thing, but finding vegan food outside is a whole different story!

It definitely includes some research and planning — although, luckily, vegan options at most restaurant chains have become much more ubiquitous. 

Bring your own food where it’s socially acceptable, check out vegan restaurants (browse Happy Cow) or do some online research before visiting a restaurant to see if they have vegan-friendly options.

Solution

Most restaurants can provide you with fully vegan meals if you just ask them — this also increases demand! Check the menu for a little (v) next to any meals, which often indicates that they are vegan. Offer to bring something to a party when invited!

Social challenges

Doing something that’s not mainstream can always lead to difficult social situations. People start questioning your decisions and feel the need to defend their diet and lifestyle.

But it’s totally possible to be vegan if your family is not or even become a vegan family together!

Solution

Stay calm and friendly when discussing your vegan diet. You can also let others know if you don’t want to talk about this subject — find specific tips for being vegan at cookouts or surviving the holidays as a vegan on our website!

Cooking your own food

Are you used to just grabbing food outside of your home or buying frozen meals? Well, as a vegan, you typically have way fewer options.

Time to start cooking your own meals more often! This also helps if you’re on a budget, and you’ll discover many new flavors and foods that way.

Solution

Check out our vegan cooking guide here and browse these beginner-friendly vegan recipes that pretty much everyone can prepare! Having to cook your own food doesn’t have to be a downside — plus, restaurant options and convenience foods are growing each year.
