The Claim

Adults following plant-based diets exhibit no meaningful differences in whole-body bone mineral density, fat mass, lean mass percentage, android/gynoid fat ratio, or BMI compared to adults following regular meat diets when nutrient intake is adequate.

Description
1 study reviewed
In plain English

When nutrient intake is adequate, adults who eat plant-based diets have the same bone density and body composition—including fat and muscle levels—as adults who eat meat-based diets.

See the scientific wording

Whole-body bone mineral density and most body composition measures—including fat mass, lean mass percentage, android/gynoid fat ratio, and BMI—are not meaningfully different between adults following plant-based diets and those following regular meat diets, suggesting that these dietary patterns do not substantially alter overall body composition when nutrient intake is adequate.

Why this might work

When the body gets enough protein, calcium, and other key nutrients, it maintains normal bone density and muscle mass, and balances fat storage in the same way whether those nutrients come from plants or animals.

  1. Study: Bone mineral density and body composition in Australians following plant-based diets vs. regular meat diets

    When people eat enough protein and calcium, whether they eat meat or not, their overall body fat, muscle, and bone density stay about the same — this study found that to be true.
