The Claim
In healthy adults undergoing 12 weeks of resistance training and consuming 1.6 g/kg/day of protein, habitual vegans and omnivores exhibit comparable increases in cross-sectional area of type I and type II muscle fibers in the vastus lateralis, indicating similar myocellular hypertrophy independent of dietary protein source.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're a vegan or meat-eater and both of you lift weights and eat the same amount of protein every day, your muscles will grow just as much over three months — it doesn't matter where your protein comes from.
See the scientific wording
Habitual vegans and omnivores consuming 1.6 g/kg/day of protein and undergoing 12 weeks of resistance training show comparable increases in vastus lateralis muscle fiber cross-sectional area, including both type I and type II fibers, indicating similar myocellular hypertrophy regardless of protein source.
What the research says
1 studyThe study found that vegans and meat-eaters who ate the same amount of protein and lifted weights for 12 weeks gained similar amounts of muscle, whether their protein came from plants or animals.
