Building Muscle on a Plant-Based Diet
Contrary to popular belief, you can build significant muscle and strength on a plant-based diet. This guide provides a roadmap for vegetarians and vegans looking to maximize their gains.
Protein Considerations
Plant Protein Sources
Top options include:
- Legumes (beans, lentils, peas)
- Tofu, tempeh, and edamame
- Seitan (wheat protein)
- Quinoa and other whole grains
- Hemp seeds, chia seeds, and nutritional yeast
Protein Quality
Plant proteins can vary in amino acid profiles:
- Combine complementary proteins (beans + rice)
- Focus on complete protein sources (soy, quinoa, hemp)
- Consider leucine content for muscle building (pea protein is high in leucine)
Protein Timing and Distribution
- Aim for 1.6-2.2g protein per kg bodyweight
- Distribute intake evenly throughout the day
- Include protein at each meal (20-40g per meal)
Caloric Considerations
Plant foods are typically less calorie-dense:
- You may need to eat larger volumes of food
- Focus on calorie-dense options like nuts, seeds, avocados
- Track your intake if you struggle to gain weight
Key Nutrients for Plant-Based Athletes
Creatine
- Not found naturally in plant foods
- Consider supplementing (3-5g daily)
- May provide even greater benefits for vegetarians than omnivores
Vitamin B12
- Essential for energy production
- Supplement or consume fortified foods
- Monitor levels through regular blood work
Iron and Zinc
- Consume with vitamin C to enhance absorption
- Consider using cast iron cookware
- Focus on legumes, pumpkin seeds, and whole grains
