Plant Protein Sources That Add Up to a Full Day's Target

Hitting a full day's protein target on plants is realistic: about 1 cup of lentils (18g), 1 cup of cooked edamame (18g), 3 oz of tempeh (16g), 2 tablespoons of peanut butter (8g), and 1 cup of cooked quinoa (8g) together reach roughly 68g, enough for most adults needing 46 to 56g daily. Other reliable building blocks include tofu, black beans, chickpeas, seitan, hemp and pumpkin seeds, soy milk, and whole grains, which collectively supply all essential amino acids when eaten across the day. Your personal number shifts with body weight, age, pregnancy, kidney health, and training load, and absorption, fiber tolerance, and iron or B12 status matter too, so there are several important factors to consider before you build a plan. See below for the full breakdown of serving sizes, gram counts, and combinations that close the gap.

If you are struggling with fatigue, hair thinning, slow recovery, muscle loss, or digestive discomfort while shifting to plant proteins, those symptoms deserve a closer look rather than guesswork, and a free, instant, online symptom check can help you understand what may be driving them and what step to take next.

Plant Based Protein Sources That Add Up to a Full Day’s Target

Meeting your daily protein needs on a plant-based diet is entirely achievable with a little planning and a diverse mix of foods. Protein supports muscle repair, immune health, hormone balance and more. This guide lays out practical, tasty options so you can hit your target—whether you’re new to plant-based eating or a seasoned pro.


Why Protein Matters

Protein is made of amino acids, some of which you must get from food. On a plant-based diet, combining different protein sources ensures you receive all essential amino acids. A balanced approach also provides fiber, vitamins, minerals and antioxidants that support overall well-being.

  • Adults generally need about 0.8 grams of protein per kilogram of body weight.
  • Active individuals, athletes or those recovering from illness may require more (1.2–2.0 g/kg).
  • Talk with your healthcare provider or a registered dietitian to fine-tune your needs.

Top Plant Based Protein Sources

Below are some of the richest plant-based protein sources, along with their approximate protein content per typical serving:

  • Legumes

    • Lentils, cooked (1 cup): 18 g
    • Chickpeas, cooked (1 cup): 15 g
    • Black beans, cooked (1 cup): 15 g
  • Soy Products

    • Firm tofu (¾ cup): 16 g
    • Tempeh (¾ cup): 21 g
    • Edamame, shelled (1 cup): 17 g
  • Whole Grains

    • Quinoa, cooked (1 cup): 8 g
    • Farro, cooked (1 cup): 6 g
    • Oats, steel-cut (1 cup cooked): 6 g
  • Nuts and Seeds

    • Almonds (¼ cup): 8 g
    • Chia seeds (2 tablespoons): 4 g
    • Hemp seeds (3 tablespoons): 10 g
    • Peanut butter (2 tablespoons): 8 g
  • Vegetables (higher-protein choices)

    • Peas (1 cup cooked): 9 g
    • Spinach (1 cup cooked): 5 g
    • Broccoli (1 cup cooked): 4 g
  • Plant-Based Protein Powders

    • Pea protein (1 scoop ~25 g): 20–25 g
    • Brown rice protein (1 scoop ~30 g): 20–25 g

Building a Full Day of Protein

Here’s how you can mix and match to reach a target of around 70–80 grams of protein per day. Adjust portion sizes to fit your personal goal.

Breakfast (15–20 g Protein)

  • Tofu Scramble

    • ½ block firm tofu (10 g)
    • 1 cup spinach + veggies (3 g)
    • 2 slices whole-grain toast (6 g)
  • Overnight Oats

    • ½ cup rolled oats (5 g)
    • 1 scoop pea protein (20 g)
    • 1 tablespoon chia seeds (2 g)

Mid-Morning Snack (5–8 g Protein)

  • 2 tablespoons peanut butter on apple slices (8 g)
  • Handful of almonds (¼ cup, 8 g)

Lunch (20–25 g Protein)

  • Quinoa Buddha Bowl

    • 1 cup cooked quinoa (8 g)
    • ½ cup chickpeas (7 g)
    • ½ cup edamame (8 g)
    • Mixed greens and veggies
  • Lentil Soup + Side Salad

    • 1 cup cooked lentils (18 g)
    • Side salad with hemp seeds (2 tbsp, 5 g)

Afternoon Snack (5–8 g Protein)

  • Hummus (¼ cup, 5 g) with carrot sticks
  • Soy yogurt (½ cup, 6 g)

Dinner (20–25 g Protein)

  • Tempeh Stir-Fry

    • ¾ cup tempeh (21 g)
    • Stir-fry veggies + tamari sauce
  • Chili

    • 1 cup black beans (15 g)
    • ½ cup lentils (9 g)
    • Tomatoes, peppers, spices

Evening Snack (Optional 5–10 g Protein)

  • Protein shake with plant-based powder (20–25 g) diluted to 5–10 g
  • Roasted chickpeas (½ cup, 7 g)

Tips for Maximizing Plant Based Protein Sources

  1. Combine Proteins
    • You don’t need to pair complementary proteins at every meal. Aim for variety over the day.
  2. Include a Source at Every Meal
    • Even small add-ins like seeds or nuts boost your total.
  3. Prep in Bulk
    • Cook beans, grains and tofu in larger batches to save time.
  4. Flavor Wisely
    • Use herbs, spices, sauces and citrus to keep meals exciting.
  5. Stay Hydrated
    • Fiber-rich foods need plenty of water to support digestion.

Monitoring Your Health

Switching to or maintaining a plant-based diet is generally safe and beneficial, but it’s wise to keep an eye on:

  • Energy levels and recovery (especially if active)
  • Signs of nutrient gaps (e.g., B12, iron, omega-3s)
  • Overall mood and mental clarity

If you experience any persistent or worrying symptoms, take a free, online symptom check, using the doctor approved Ubie Symptom Checker. It’s a quick way to get personalized guidance before scheduling a medical appointment.


When to Speak to a Doctor

Always reach out to a qualified healthcare provider if you encounter:

  • Severe fatigue or unexplained weight changes
  • Digestive distress that doesn’t improve
  • Symptoms that could be life-threatening (e.g., chest pain, difficulty breathing, severe allergic reactions)

Your doctor can order lab tests, recommend supplements (such as B12 or iron), and tailor advice to your unique situation.


Sample Daily Protein Total

Meal Protein (g)
Breakfast 20
Morning Snack 8
Lunch 22
Afternoon Snack 6
Dinner 23
Evening Snack 7
Total 86 g

Adjust portions to match your individual target. If you need more protein, increase servings of legumes, tofu, tempeh or add a plant-based protein shake.


By planning your meals around a variety of legumes, soy products, whole grains, nuts and seeds, you can confidently meet—and even exceed—your daily protein goals on a plant-based diet. Always listen to your body, track your progress, and speak to a doctor about any serious or lasting health concerns. Enjoy the journey to a balanced, energized you!
