Exercise & FitnessPlant vs Animal Protein for Muscle Building: New Research Reveals Surprising Results
A new study comparing vegetarian versus omnivore diets in women doing resistance training found no differences in muscle thickness, body composition, or strength gains, despite the omnivore group consuming more protein (1.3 vs 1.0 g/kg). However, this occurred in young, untrained participants where the powerful training stimulus masks nutritional differences. For experienced or older trainees, protein source becomes more important due to animal proteins' higher leucine content and digestibility.
