Nutrition
How much protein per day on a vegan diet?
Short answer
Roughly ~0.8 g/kg for sedentary people, more with sport (about 1.2–2.0 g/kg depending on the discipline). Plants fill you with fibre, so density matters: tofu, seitan, legumes — not salad alone.
The 0.8 g/kg figure is an RDA for the general population, not a magic vegan number. Sport raises needs for everyone.
Specific training goals belong with a sports dietitian. This is not medical advice.
