Switching to a vegan diet plan? Here’s what you need to know before making the change.
You’ll need a B12 supplement
Vitamin B12 occurs naturally only in animal foods. Going on a vegan diet means consuming no animal products at all, then you will want to stock up on a variety of B12-fortified foods as well as a B12 supplement.
B12 is a fundamental vitamin; it keeps the body’s nerve and blood cells healthy and helps make DNA. A deficiency can lead to tiredness, weakness, constipation, loss of appetite, weight loss (the bad kind), nerve problems, and depression. To find out if you need to up your intake, ask your doctor for a simple blood draw.
…And maybe an iron supplement, too
Iron comes in two forms: heme and non-heme. Heme, which makes up about 40% of the iron in animal foods, is simply absorbed by the body. Vegan diets contain only non-heme, which is less readily absorbed. That means you may need to ingest more iron if you want to get the same benefit, says New York City nutritionist Christian Henderson, RD.
Good vegan iron sources contain legumes, sunflower seeds, dried raisins, and dark, leafy greens. Vitamin C-rich foods (think: red peppers, citrus, and broccoli) aid iron absorption.
Your friends and family will ask a lot of questions
Maybe you have decided before to start a vegan diet due to hearing that plant-based food can promote better health. Or maybe you wish giving up meat will kick-start weight loss. (There’s something to that notion; one study of 40,000 adults by Oxford University researchers found that meat-eaters had the highest BMIs and vegans had the lowest.) Or perhaps ethical concerns have led you to embrace veganism.
Whatever your reason, expect people in your social circle to notice and ask questions. “People are very sensitive about their diets, particularly when you challenge what they have always believed,” says plant-based dietitian Julieanna Hever, RD.
“The best way to minimize conflict is to emphasize that you are going vegan for your own reasons and that it seems to work for you. In other words, make it about you, so nobody feels they need to defend their options.”
You’ll have to find new protein sources
Every meal has to include protein, says vegan dietitian Valerie Rosser, RD. Proteins are the building blocks of life; they break down into amino acids that promote cell growth and repair. The Institute of Medicine suggests that adults get at least 0.8 grams of protein daily for every kilogram of body mass—that’s about 54 grams for a 150-pound woman.
The perfect sources of vegan protein include natural soy, lentils, beans, quinoa, and seitan, says Rosser.
You shouldn’t replace animal products with junk
Swapping out meat for white bread, chips, and other packaged foods set you up for failure on a vegan diet, says Rosser. “It’s not a good idea to trade in animal products, which contain protein, vitamins, and minerals, for processed foods that provide little nutritional value other than calories.” The result: hunger, weight gain, and a grumpier mood.
Take it easy on soy-based products
Though scientists are still arguing over the effects of soy-based food products on cancer and heart health, one thing is for certain: “Consuming too much soy-based vegan ‘meat’ is arguably worse (than) consuming high-quality animal products,” says Henderson.
Meat substitutes are usually highly processed and loaded with sodium and preservatives. Read the labels carefully. You should know the healthiest sources of soy are miso, tempeh, tofu, soy milk, and edamame.
You don’t have to go vegan at once
You won’t just wake up one morning magically vegan. It takes work, so it has to take time, Henderson says. “Start by adding more plant-based foods to your diet, while at the same time cutting back on animal products, especially those that are non-organic, and more importantly processed, refined foods. Making progressive changes and assessing how you are feeling along the way is the secret,” she says.
Be prepared to read food labels
If you’re serious about being vegan, checking food labels and verifying ingredients is necessary. “we must know that a food product is not glaringly non-vegan doesn’t mean that it’s suitable for a vegan diet,” says Rosser. Casein and whey, which come from milk, are present in many cereal bars, bread, and granolas, whereas gelatin and tallow (also known as suet) are derived from meat. Then there’s Natural Red 4 (also known as carmine, cochineal, or cochineal extract), which is a food coloring derived from the dried bodies of female beetles. Head spinning yet?

You won’t have to ditch your favorite restaurants
Just as veganism is becoming more popular, so are vegan options on restaurant menus. Word to the wise: Even if your item of option looks vegan, tell your waiter about your dietary restriction to be sure that no animal products are used to make your meal (believe hidden butter or chicken stock), advises Henderson.
It doesn’t have to cost more
At $3 or more per pound, meat is one of the most expensive items in the grocery store, so saving big can be easy—even if you are buying more products than ever. Save even more by swapping a little amount of your fresh produce for frozen.
