The Claim
Lower body mass index and waist circumference in vegetarians are associated with reduced bone mineral density, consistent with the mechanical loading effect of body weight on bone rather than nutrient deficiencies alone.
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.
Vegetarians with lower body weight and smaller waist size have lower bone mineral density, which is explained by reduced mechanical stress on bones from lower body weight, not by nutrient deficiencies.
See the scientific wording
Lower body mass index and waist circumference in vegetarians are associated with reduced bone mineral density, consistent with the known mechanical loading effect of body weight on bone, rather than nutrient deficiencies alone.
Lighter body weight means less force presses on bones during movement and standing, which signals bones to slow down the process of building new bone tissue, leading to lower bone density.
What the research says
1 studyVegetarians tend to be lighter, and lighter people have less weight pressing on their bones, which can make bones less dense. This study found that once you account for body size, the difference in bone density between vegetarians and meat-eaters mostly disappears — meaning it’s likely the weight, not the diet, that’s causing the difference.
