The Claim
A high-protein vegan diet rich in mycoprotein (approximately 2 g·kg⁻¹·day⁻¹) supports daily myofibrillar protein synthesis rates and skeletal muscle hypertrophy to a similar extent as a high-protein omnivorous diet in healthy young adults undergoing 10 weeks of high-volume resistance training.
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.
In healthy young adults performing 10 weeks of high-volume resistance training, a vegan diet providing 2 grams of protein per kilogram of body weight daily from mycoprotein results in the same rate of muscle protein synthesis and muscle growth as a diet with the same amount of protein from animal sources.
See the scientific wording
A high-protein vegan diet rich in mycoprotein (approximately 2 g·kg⁻¹·day⁻¹) supports daily myofibrillar protein synthesis rates and skeletal muscle hypertrophy to a similar extent as a high-protein omnivorous diet in healthy young adults undergoing 10 weeks of high-volume resistance training, indicating that protein source does not limit muscle adaptation when total protein intake is adequate.
When a person eats enough protein from any source, the amino acids from that protein enter the bloodstream and trigger a molecular signal in muscle cells that turns on protein building. This signal, activated by the amino acid leucine, tells the muscle cells to make more of the contractile proteins that make up muscle fibers. When combined with heavy resistance exercise, this process happens more strongly and consistently over weeks, causing muscle fibers to grow larger and stronger, regardless of whether the protein came from plants or animals.
What the research says
1 studyIn a study where people lifted weights for 10 weeks, those eating only plant-based protein (from mycoprotein) built muscle and got stronger just as much as those eating meat, as long as they ate the same total amount of protein.
