One of the first things people worry about when switching to a plant-based diet is protein. And fair enough — protein is essential for muscle repair, immune function, hormone production, and keeping you full. But here's the truth: getting enough on a plant-based diet is absolutely doable. You just need to know which foods deliver, and how to combine them strategically.
How Much Protein Do You Actually Need?
The general guideline is 0.8g of protein per kilogram of bodyweight for sedentary adults. If you exercise regularly — especially resistance training — most sports nutritionists recommend 1.6–2.2g per kg. So a 70kg person who trains would aim for roughly 112–154g of protein per day.
Top Plant-Based Protein Sources
- Pea protein powder — 24g per 30g scoop (80% protein purity). The easiest, most concentrated source.
- Lentils — 18g per cooked cup. High in fibre and iron too.
- Chickpeas — 15g per cooked cup. Incredibly versatile.
- Tofu (firm) — 17g per 150g serving. A complete protein.
- Tempeh — 21g per 100g. Fermented, gut-friendly, and protein-dense.
- Edamame — 18g per cooked cup. One of the few complete plant proteins.
- Hemp seeds — 10g per 3 tablespoons. Easy to sprinkle on anything.
- Black beans — 15g per cooked cup.
The Complete Protein Question
You've probably heard that most plant proteins are "incomplete" — meaning they're missing one or more essential amino acids. This is true for individual foods, but it's not something to stress about. As long as you eat a variety of plant foods throughout the day, your body assembles a full amino acid profile. Pea protein is notably high in all essential amino acids except methionine — pair it with hemp seeds or grains to cover the gap.
Practical Tips to Hit Your Numbers
- Start your day with protein. Add a scoop of pea protein to your morning smoothie or oatmeal. That's 24g before 9am.
- Build every meal around a protein anchor. Lentils in your salad, tofu in your stir fry, chickpeas in your curry.
- Snack strategically. Edamame, roasted chickpeas, or hemp hearts on yogurt.
- Track for a week. Most people are surprised to see how much (or how little) they're actually getting. Use Cronometer or MyFitnessPal.
- Use protein powder where it makes sense. Unflavoured pea protein blends into smoothies, soups, and baked goods invisibly. It's not a crutch — it's a tool.
The Bottom Line
Plant-based diets can absolutely support high protein intake and athletic performance. It takes a bit more planning than reaching for chicken breast, but once you build the habits, it becomes second nature. Start with whole foods, fill gaps with a clean protein powder, and track until you trust your instincts.
