Free Vegan Diet Builder | Plan Your Plant-Based Meals and Hit Your Protein Targets

The vegan protein challenge: building muscle using only plant-based foods. No meat, fish, eggs, or dairy.

Vegan athletes often aim for a higher daily protein intake using only plant sources. Unlike vegetarians who can rely on foods like eggs and Greek yogurt, plant-based diets require thoughtful food selection to reach protein targets while maintaining balanced macros.

Our vegan diet builder helps simplify the process with 29 carefully selected vegan foods, including protein-rich options like tofu, lentils, quinoa, soy milk, and TVP.

Build custom meal plans based on your protein, carbs, fat, and calorie targets. Use Smart Fill to automatically generate balanced vegan days that match your macro goals. When you’re finished, download your plan as a free PDF for easy grocery shopping.

100% plant-based. No animal products.

Need eggs and dairy? Switch to our Vegetarian Diet Builder with 33 foods including Greek yogurt, eggs, and paneer.

Need meat and fish? Try the Omnivore Diet Builder with 37 foods. It also has a detailed guide on how to use NatFit Pro diet builders.

How to Use the Vegan Diet Builder

You can build a full plant-based meal plan in just a few minutes.

1. Set your macro targets: Enter protein, carbs, and fat in grams (or just calories; the tool auto-calculates macros). Don’t know your numbers? Use our TDEE calculator to find your personalized targets.
2. Select foods: Click “+ Add Food” → Choose category (Protein, Carbs, Fat) → Choose from the list of vegan foods → Enter the quantity in grams.
3. Adjust quantities: Watch the 4 progress bars (Calories, Protein, Carbs, Fat). Green = perfect, Orange = acceptable, Red = adjust.
4. Smart Fill (optional): Click “Smart Fill” to auto-generate a balanced day across 5 meals. The algorithm balances foods to help match your macro targets. Protein is usually the main focus for vegan diets, but our vegan diet planner also balances carbohydrates and fats to match your macro targets. Treat it as a starting point. You can edit meals, change quantities, or swap foods anytime.
5. Download PDF: Click “Download PDF,” enter email, get your meal plan with a grocery list.

Complete Vegan Protein Sources for Muscle Building

Can vegans build muscle? Yes. With adequate calories and about 1.6-2.2 grams of protein per kilogram of body weight, plant-based athletes can support muscle growth and recovery.

The major challenge is protein quality. Many plant foods contain lower amounts of certain essential amino acids compared with animal proteins.

The practical solution is simple. Include complete plant proteins such as soy foods and quinoa, and combine a variety of plant foods like legumes, grains, nuts, and seeds throughout the day. This variety provides the full spectrum of essential amino acids needed for muscle repair and growth.

Vegan Protein Sources Ranked by Density

Tier 1 – High Density (20g+ per 100g raw)

These are your muscle-building workhorses:

Food	Protein Per 100g	Complete?
TVP (Soya Chunks)	51.1 g	✅ Yes
Lentils (dry)	23.6 g	⚠️ No
Kidney Beans (dry)	23.6 g	⚠️ No
Black Beans (dry)	21.6 g	⚠️ No
Chickpeas (dry)	21.3 g	⚠️ No

Note: Cooked legumes contain about 8-9 g of protein per 100 g because they absorb water during cooking.

Tier 2 – Moderate Density (9-20g per 100g)

Versatile, everyday protein sources:

Food	Protein Per 100g	Complete?
Tempeh	19 g	✅ Yes
Quinoa (raw)	14.1 g	✅ Yes
Oats (raw)	13.5 g	⚠️ No
Whole Wheat Bread	12.3 g	⚠️ No
Tofu (Firm)	9.1 g	✅ Yes

Key insight: A 75kg (165 lb) vegan athlete needs 120-165g of protein per day approximately (changes based on specific goals). This requires strategic food combining; you can’t rely on quinoa and tofu alone.

The Protein Pairing Strategy (Complete Amino Acids)

The science: Legumes are rich in lysine but relatively low in sulfur amino acids such as methionine, while grains provide more methionine but less lysine. When these foods are eaten across the day, they complement each other and provide a balanced amino acid profile.

You don’t need to combine them in the same meal. Eating a variety of plant foods throughout the day allows the body to draw from its circulating amino acid pool.

Proven Protein Pairings

Example vegan day (100 g protein from whole foods):

Here is a realistic example built using the foods in the NatFit Pro Vegan Diet Builder.

Why Seitan and Nutritional Yeast Aren’t in the Vegan Diet Builder Database

You may notice two popular vegan protein foods are missing from the default database, even though they are commonly recommended in our Vegan Protein Sources for Muscle Building guide.

Seitan (Wheat Gluten)

Protein: 75-80 g per 100 g (dry)

Seitan is made from wheat gluten and is one of the most protein-dense plant foods available. However, the final protein content varies widely depending on how it is prepared. Hydrated seitan products sold in stores can range from roughly 15-30 g protein per 100 g because water content differs significantly by brand and recipe.

The USDA database contains many separate entries for wheat gluten and seitan-style foods, which can lead to inconsistent macro values when building a standardized food database.

Nutritional Yeast

Protein: 45-50 g per 100 g

Nutritional yeast is another very high-protein vegan ingredient. However, its nutritional profile varies depending on the brand fortification. Some products are fortified with vitamins such as B12, while others are not, resulting in multiple database entries with different values.

Our approach

The NatFit Pro Diet Builder focuses on foods with stable and consistent nutrition data so macro calculations remain reliable.

The solution

If you regularly use seitan or nutritional yeast, you can add them as custom foods in the Pro version (up to 10 custom entries). Simply enter the macros from your product’s nutrition label.

This allows you to track the foods you actually eat while keeping the core database clean and consistent.

Vegan vs Vegetarian vs Omnivore Diet Builders

Why Calories Don’t Match the 4-4-9 Formula

You may notice that calories do not always match the simple formula
Protein × 4 + Carbs × 4 + Fat × 9. This is normal.

Why the difference?

The 4-4-9 rule is a simplified energy estimate developed in the late 1800s by Wilbur Atwater. It works well as a general guideline, but real foods contain fiber, organic acids, and other compounds that affect how energy is calculated.

What we use

The NatFit Pro Diet Builder uses calorie values directly from USDA FoodData Central, which calculates energy using Atwater factors. These factors can vary slightly depending on the type of food.

Example

Manual estimate for 100 g tempeh:

(Protein 20.3 g × 4) + (Carbs 7.64 g × 4) + (Fat 10.8 g × 9) = 208.9 calories

USDA value: 192 calories

The difference comes from food-specific energy factors used by the USDA database.

Bottom Line: Small differences of 5-10% are normal when comparing the 4-4-9 estimate with official USDA energy values.

About This Vegan Diet Builder Tool

I’m Tamil Arasan, founder of NatFit Pro. Over the past 10+ years, I’ve coached clients using omnivore, vegetarian, and vegan approaches depending on their goals.

My personal diet: I follow a flexible omnivore approach (read my transformation), but I regularly plan fully plant-based days and have coached vegan clients to build muscle successfully.

Why I built this: Vegan lifters face a different challenge. No eggs (12.4 g protein per 100 g), no Greek yogurt (10.3 g per 100 g), and no whey protein. Many clients have asked me, “Can I still build muscle on a vegan diet?” Yes, if you understand complete proteins and smart food pairing.

This vegan diet builder highlights key vegan protein sources like tofu, tempeh, quinoa, soy milk, TVP, hemp seeds, chia seeds, and amaranth, while also showing how legumes and grains work together to form complete amino acid profiles.

My philosophy: I don’t push one diet style. Whether you’re vegan for ethics, health, or environmental reasons, macro-based planning works the same. The only thing that changes is the food selection.
