The Claim
In non-obese adults, caloric restriction does not improve cognitive performance via changes in total daily energy expenditure or physical activity, as these factors are no longer statistically associated with cognition when resting metabolic rate is controlled for.
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 people who are not overweight, eating fewer calories does not lead to better thinking skills by changing how much energy they use in a day or how active they are, because those changes are not linked to thinking ability once their resting metabolism is taken into account.
See the scientific wording
Caloric restriction does not improve cognitive performance through changes in total daily energy expenditure or physical activity in non-obese adults, as these factors lose statistical association with cognition when resting metabolic rate is accounted for.
What the research says
1 studyWhen people eat less but aren’t overweight, their brain performance gets better—not because they move less or burn fewer calories overall, but because their body’s baseline energy use (resting metabolism) changes in a way that helps the brain. The study shows this effect isn’t tied to how much they exercise or eat.
