High-Protein Vegan Diet Plan: How to Build One
TL;DR
- Target: 1.6–2.2 g protein per kg body weight per day
- Best sources: soy (tofu/tempeh/edamame), seitan, lentils, beans, pea/soy protein
- Combine sources across the day to cover all amino acids
- Supplement: B12 (essential), plus D, algae omega-3, iron, creatine
1) Yes, you can build muscle and lose fat vegan
The idea that you "can't get enough protein" on plants is outdated. With a bit of planning, a vegan diet supports muscle gain and fat loss just as well as an omnivore diet. The two rules are identical for everyone: hit your total daily protein and set calories to your goal (surplus to build, deficit to lean out). Plants just need a little more intention because protein is less concentrated.
2) Your protein target
Aim for 1.6–2.2 g of protein per kg of body weight per day. Because plant proteins each have slightly different amino-acid profiles, eat a variety across the day (e.g. soy + grains + legumes) so you cover all the essential amino acids, including leucine which drives muscle building.
3) Best vegan protein sources
| Food | Serving | Protein |
|---|---|---|
| Seitan | 100 g | ~25 g |
| Tempeh | 150 g | ~28 g |
| Tofu (firm) | 150 g | ~18 g |
| Edamame | 150 g | ~17 g |
| Lentils (cooked) | 200 g | ~18 g |
| Chickpeas (cooked) | 200 g | ~15 g |
| Soy or pea protein | 1 scoop | ~24 g |
4) A sample high-protein vegan day (~140 g)
- Breakfast: soy yoghurt + berries + 1 scoop soy protein + oats (~35 g)
- Lunch: tempeh stir-fry with rice and edamame (~38 g)
- Snack: hummus + wholegrain pitta + soy milk (~20 g)
- Dinner: seitan or tofu with lentils, quinoa and veg (~45 g)
Tracking is where most people slip — plant meals can look high-protein but fall short. KeplerFit estimates protein and calories from a photo of your plate, so you can confirm you actually hit your target. Try it →
5) Supplements vegans should consider
- Vitamin B12 — essential. Not reliably found in plants; supplement daily or weekly.
- Vitamin D (especially in winter / less sun).
- Algae omega-3 (EPA/DHA) — a vegan source of the fats found in fish oil.
- Iron — pair plant iron with vitamin C; check levels if tired.
- Creatine — vegans often start with lower stores, so may benefit most.
FAQ
Can you build muscle on a vegan diet?
Yes — with enough protein (1.6–2.2 g/kg), calories and training, results match an omnivore diet.
Best vegan protein sources?
Soy (tofu, tempeh, edamame), seitan, lentils, beans, and soy/pea protein powder.
How much protein do vegans need?
The same as anyone training: 1.6–2.2 g/kg, spread across 3–4 meals.
What supplements?
B12 is essential; also consider D, algae omega-3, iron and creatine.
