your protein target doesn't really change without meat — aim for 1.2–1.6 g per kilogram of body weight per day, leaning toward the top of that range since plant protein digests slightly less efficiently. The heavy lifters are soy foods, legumes, seitan, nuts, and whole grains.Example: at 70 kg (155 lb), that's roughly 100–115 g of protein a day — very doable with tofu, lentils, chickpeas, and peanut butter.
"But where do you get your protein?" is the first question everyone hears after dropping meat. The honest answer: from plenty of places — once you know the real numbers behind the best plant-based protein sources instead of internet folklore. Here's a gram-by-gram breakdown, the truth about "incomplete" protein, and a sample day that lands at 100 grams with no meat at all.
01. Can you actually build muscle without meat?
Yes — and this stopped being controversial years ago. What matters most for muscle and health is total daily protein and calories, not whether the grams came from chicken or chickpeas. One real caveat: plant protein is a bit less digestible on average, and some foods have weaker amino acid profiles. The fix is simple — eat about 10–15% more protein than the standard "meat-eater" target and don't build your diet around one single food. Sports nutrition bodies cite up to 1.6–2.0 g per kilogram for hard training — fully reachable on plants. Vegetarians who kept eggs and dairy have it even easier — those two quietly cover a big chunk of the target.
02. The best plant-based protein sources, with numbers
The fairest way to compare foods is grams of protein per 100 g as eaten — it separates the workhorses from foods that merely "contain protein" on the label.
| Food | Protein per 100 g | Worth knowing |
|---|---|---|
| Seitan | 20–25 g | nearly pure wheat gluten; off the table for celiac |
| Tempeh | 18–20 g | fermented soy, dense and filling |
| Firm tofu | 12–17 g | the firmer the block, the more protein |
| Edamame | 10–12 g | young soybeans, a ready-made snack |
| Cooked lentils | 8–9 g | bonus iron and fiber |
| Cooked chickpeas and beans | 7–9 g | the base for hummus, curries, and chili |
| Peanut butter | 24–26 g | calorie-dense: one tablespoon is ~4 g protein |
| Cooked quinoa | 4–5 g | a rare grain with a complete amino acid profile |
Watch the peanut butter trap: the per-100-g number looks great but arrives packaged with 500–600 calories. Nuts are excellent supporting actors, not lead roles.
03. The "incomplete protein" myth
The classic argument against plants goes: their protein is "incomplete," so your muscles will starve. It's built on a real fact — grains run low on lysine, legumes on methionine — but the conclusion is decades out of date. Amino acids don't expire at midnight: your body pools everything you eat across the day, so variety over 24 hours does the job. Classic combos like rice and beans or hummus on bread solve the "problem" on their own. And soy, quinoa, and buckwheat contain all essential amino acids outright — incompleteness is a symptom of a monotonous diet, not of plants themselves.
04. A sample day that hits 100 grams
Here's an ordinary meat-free day that covers the target for someone around 70 kg:
- breakfast: oatmeal made with soy milk + 2 tablespoons of peanut butter — about 20 g;
- lunch: lentil soup with whole-grain bread and hummus — about 25 g;
- dinner: pan-fried tofu (200 g) with buckwheat and vegetables — about 30 g;
- snacks: edamame, soy yogurt, a handful of almonds — another 20–25 g.
That's 95–100 g without exotic ingredients or gram-counting. Need more? Add a serving of tempeh or seitan at lunch and you're there.
batch-cook legumes for two or three days at a time, or keep canned chickpeas and beans on the shelf — a can solves "I have nothing to add protein with" in about a minute. Frozen edamame and firm tofu also keep for weeks.
05. Powders, B12, and the fine print
Vegan protein powder — soy, or a pea-rice blend — is a convenience, not a requirement: handy after workouts or on the road, but regular food does the job. What genuinely matters on a fully plant-based diet is vitamin B12: plants have essentially none, and supplementing it is the standard recommendation for vegans. Iron, zinc, and omega-3s deserve a spot on your radar too — not as a panic item, but as "legumes, seeds, and nuts show up regularly." Specific supplement doses are a conversation for your doctor, not a blog post.
The bottom line
Plant-based protein isn't a compromise — it's a system that works: 1.2–1.6 g per kilogram with a small buffer on top, and your muscles won't miss the meat. Soy in all its forms, legumes, and seitan carry the load; grains and nuts fill the gaps. "Incomplete protein" is a myth once your diet has variety, and the one truly non-negotiable supplement for vegans is B12. Start simple: put one solid protein food in every meal, and the daily total takes care of itself.
