It’s not a big difference, but vegans should strive for a protein intake of 0.9 grams per kilogram of body weight. This translates to around 0.4 grams of protein per pound of body weight. So a vegan who weighs 150 pounds would need 60 grams of protein (150 × 0.4) per day. Although the RDA for protein is based on total body weight, nutritionists often calculate protein needs based on “ideal” body weight. That’s because fat tissue maintenance requires very little protein. You can find a number of calculators online to determine your ideal body weight.
