Summary:
Brain images of 94 elderly adults were studied over 5 years
Brains of obese subjects were 8% smaller and of overweight subjects 4% smaller than those of normal-weight participants
In a Healthday interview, researchers speculated results may be due to poor nutrient delivery to the brain of overweight/obese people, which could be improved by exercise
Conclusion: Brains of overweight and obese older adults are smaller than brains of normal weight people, especially in frontal and temporal lobes
