The Claim
In resistance-untrained women, strict vegetarian and nonvegetarian diets are associated with similar levels of total and regional lean mass, bone mineral content, bone mineral density, knee extension peak torque, knee flexion peak torque, and countermovement vertical jump, despite differences in macronutrient and calcium intake.
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 women who do not regularly perform resistance training, those following strict vegetarian diets have the same levels of muscle mass, bone density, and lower-body strength as those following nonvegetarian diets, even though their nutrient intake differs.

In resistance-untrained women, strict vegetarian and nonvegetarian diets are associated with similar levels of total and regional lean mass, bone mineral content, bone mineral density, knee extension peak torque, knee flexion peak torque, and countermovement vertical jump, despite differences in macronutrient and calcium intake.
The body uses available protein efficiently to maintain muscle and bone, even when dietary intake is lower, and daily movement keeps muscles and bones strong without needing more protein or calcium.
What the research says
1 studyIn women who don’t lift weights, whether they eat meat or not didn’t make a difference in their muscle mass, bone strength, or jumping power—even though vegetarians ate less protein and calcium. Both groups ended up with similar physical strength and body composition.
