The Claim
When total protein intake is matched at approximately 2 g·kg⁻¹·day⁻¹, a vegan diet supports comparable increases in muscle strength during resistance training as an omnivorous diet, and neuromuscular adaptations to training are not impaired by the absence of animal-derived protein.
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.
When people consume the same amount of protein per kilogram of body weight, those following a vegan diet gain the same amount of muscle strength from resistance training as those following an omnivorous diet, and their neuromuscular adaptations to training are not reduced by avoiding animal-derived protein.
See the scientific wording
When total protein intake is matched at approximately 2 g·kg⁻¹·day⁻¹, a vegan diet can support comparable increases in muscle strength during resistance training as an omnivorous diet, indicating that neuromuscular adaptations to training are not impaired by the absence of animal-derived protein.
When a person eats enough protein every day from plants or animals, their muscles use the amino acids to build more contractile proteins, making the muscle fibers thicker and stronger over time. Resistance training makes the muscles more responsive to these amino acids, so the same amount of protein from any source leads to the same muscle growth and strength gains.
What the research says
1 studyWhen people eat the same amount of protein every day, whether from plants or animals, they gain the same amount of muscle strength and size from weight training. The study showed vegans and meat-eaters improved equally.
