Building muscle on plants requires attention to protein quantity (1.6-2.2g/kg), protein quality (complementary amino acids), leucine threshold (2.5-3g/meal), and B12/iron/zinc status.
🧬 Protein Strategy
2.5-3g leucine per meal triggers mTORC1. Harder on plants — need more total protein. Soy, pea, and lentil proteins are leucine-rich.
Foods: Tempeh (2.5g leucine/150g), tofu (2.1g/200g), lentils (1.3g/200g — need more volume)
Grains low in lysine, high in methionine. Legumes low in methionine, high in lysine. Combine: rice + beans, hummus + pita, oats + soy milk.
Foods: Rice + lentils. Whole wheat bread + peanut butter. Quinoa (complete protein). Soy (complete).
30-40g protein per meal, 4-5 meals/day. Plant protein digests slower — maintain steady amino acid supply.
Foods: Breakfast: tofu scramble. Lunch: lentil + quinoa bowl. Dinner: tempeh stir-fry. Snack: protein shake (pea/rice blend).
⚠️ Nutrients to Monitor
Risk: Naturally absent from plants. Deficiency = fatigue, nerve damage, elevated homocysteine.
Solution: Supplement 1000μg cyanocobalamin 2-3x/week or 50μg daily. Nutritional yeast (fortified).
Risk: Non-heme iron absorbs 2-20% vs 15-35% heme. Phytates in plants reduce absorption.
Solution: Pair iron sources with vitamin C (lentils + bell peppers). Avoid coffee/tea with meals. Cook in cast iron.
Risk: Phytates in grains/legumes reduce zinc absorption 50%.
Solution: Soak/sprout/ferment legumes and grains. Pumpkin seeds, tahini. Supplement if deficient.
Risk: ALA from flax/walnuts converts to DHA at only 5-10% efficiency.
Solution: Algal oil supplement (200-300mg DHA/day).
