Thinking about reducing your meat intake but unsure where to start? Transitioning to a vegetarian diet can feel overwhelming at first, but don’t worry—it's much easier (and tastier) than you might think!

Whether your motivation is health, the environment, or ethical reasons, here are practical tips from TeamNutrition’s registered dietitians and nutritionists to help you embrace vegetarianism with confidence—without frustration or nutritional deficiencies.

1. Take it one step at a time

Changing your diet doesn’t mean you have to overhaul everything overnight. A gradual approach increases your chances of long-term success!

  • Start with one vegetarian day per week, like the popular Meatless Monday.
  • Try vegetarian versions of your favourite meals, such as a bean-based chili or shepherd’s pie with lentils.
  • Plan your vegetarian meals in advance to avoid last-minute, less balanced choices.

If you prefer to switch overnight, that’s perfectly fine too! The key is to go at your own pace while maintaining a balanced diet that works for you.

2. Smart meat substitutions

One of the first concerns people have is: “How will I get enough protein?” The good news? There are plenty of options!

Plant-based protein sources

  • Legumes (chickpeas, lentils, black beans, etc.) – Great in soups, curries, pureed in creamy soups, or even in baked goods like muffins and cookies. Try legume-based pasta as a high-protein alternative to traditional pasta.
  • Tofu, tempeh, and edamame – These soy-based foods are complete protein sources. Tofu and tempeh absorb flavours well when marinated or grilled, while edamame (young soybeans) make a great snack, salad addition, or side dish.
  • Textured Vegetable Protein (TVP) – A lesser-known soy-based product that works as an excellent ground meat substitute in chili, tacos, or veggie burgers. You can even grind it into flour and mix it into baked goods (like muffins) to boost protein content without altering texture.
  • Quinoa – A whole grain with more protein than most grains, perfect for salads, as a side dish, or in patties.
  • Seeds and nutsHemp seeds and pumpkin seeds are excellent protein sources. Almonds and walnuts are mainly sources of healthy fats, but they add a little extra protein and a crunchy texture to baked goods, yogurt, and salads.

Pro Tip: Combine different protein sources throughout the day to ensure you're getting all essential amino acids.

For lacto-ovo and pesco-vegetarians

If you still include animal products, you can also get protein from:

  • Dairy and eggs – Greek yogurt, skyr, cottage cheese, eggs, and high-protein milk (ex.: Natrel Plus).
  • Fish and seafood – Salmon, trout, shrimp, mussels, oysters, etc.
3. Adapt your favourite recipes

You don’t have to give up your favourite dishes! With a few tweaks, they can be just as delicious:

  • Bolognese – Replace ground beef partially or completely with lentils.
  • Burgers – Try a chickpea or black bean patty.
  • Tacos – Homemade seasoned TVP tastes better (and is lower in sodium) than store-bought meat alternatives.
  • “Chicken wings” – Try caramelized tofu—it’s amazing!
  • General Tao – Swap chicken for crispy tofu or marinated tempeh.

Pro Tip: Be generous with garlic, ginger, smoked paprika, cumin, and fresh herbs—whatever flavours you love! When cooking vegetarian meals, don’t be afraid to season boldly. For example, if you’re swapping ground beef for TVP in your spaghetti sauce, add extra seasoning to enhance the flavours.

4. Ensure proper nutritional balance

Eating vegetarian is great—but avoiding nutrient deficiencies is key! Here are some essential nutrients to monitor:

Key nutrients to watch for

  • Iron – Found in edamame, lentils, white beans, spinach, and pumpkin seeds. Pair with vitamin C-rich foods like bell peppers or citrus fruits to boost absorption.
  • Vitamin B12 – Rare in plant-based foods, but available in fortified products (plant-based milks, cereals). A supplement may be necessary—ask a dietitian for guidance.
  • Omega-3s – Found in flaxseeds, chia seeds, and walnuts for plant-based sources. For DHA and EPA, look for algae-based supplements or oils.
  • Calcium – Get it from fortified plant-based milks, firm tofu (calcium sulfate), almonds, sesame seeds (tahini), and leafy greens (kale, spinach).

Pro Tip: Not sure if you’re getting enough nutrients? A registered dietitian specializing in vegetarian and vegan nutrition can help ensure your diet is balanced!

5. Avoid common mistakes
  • Not eating enough protein – Make sure to include legumes, tofu, TVP, eggs, etc. in every meal.
  • Relying too much on ultra-processed foods – Some store-bought meat substitutes are high in sodium and additives. Prioritize homemade options!
  • Thinking “vegetarian” always means “healthy” – Some vegetarian foods (like fries or pastries) offer little nutritional value. Check labels to make balanced choices and avoid excessive sugars, salt, and saturated fats.
  • Lack of variety – The more diverse your diet, the better! Experiment with new ingredients and recipes to keep things exciting.

Embrace vegetarianism with ease

Switching to a vegetarian diet is an opportunity to discover new flavours, enjoy food differently, and make a positive impact on both your health and the planet. So go ahead—explore, experiment, and most importantly, have fun in the kitchen!
