The Claim
Resting metabolic rate mediates the relationship between caloric restriction and cognitive performance, independent of changes in body weight, fat mass, or fat-free mass, indicating that metabolic regulation is the primary physiological pathway underlying this relationship.
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 eat fewer calories, their cognitive performance may change due to shifts in resting metabolic rate, not because of changes in their weight or body fat. The key factor appears to be how the body regulates energy use at rest.
See the scientific wording
The relationship between caloric restriction and cognitive performance is mediated by resting metabolic rate, not by changes in body weight, fat mass, or fat-free mass, indicating that metabolic regulation, not body composition, is the primary physiological pathway.
What the research says
1 studyWhen people eat fewer calories, their brain works better—but not because they lose weight or fat. Instead, it’s because their body’s internal energy use (resting metabolism) changes, and that’s what helps the brain.
