The Claim
In young adults undergoing resistance training, muscle strength increases comparably on a high-protein vegan diet versus an omnivorous diet, with no significant differences in 1RM gains for squat, deadlift, and bench press, indicating that protein source does not limit neuromuscular adaptation.
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.
Young adults who lift weights gain the same amount of strength whether they eat a high-protein vegan diet or a high-protein omnivorous diet, as measured by maximum lifts in squat, deadlift, and bench press.
See the scientific wording
In young adults undergoing resistance training, muscle strength increases comparably on a high-protein vegan diet versus an omnivorous diet, with no significant differences in 1RM gains for squat, deadlift, and bench press, suggesting that protein source does not limit neuromuscular adaptation.
When someone lifts weights and eats enough protein, whether from plants or animals, the amino acids from the protein turn on a cellular switch in muscle cells that tells them to build more contractile proteins. This causes muscle fibers to grow thicker over time, which makes the muscles stronger.
What the research says
1 studyPeople who ate only plant-based protein while lifting weights got just as strong and built just as much muscle as those who ate meat and dairy—so the source of protein doesn’t matter if you’re eating enough of it.
