BRAIN HEALTH AND WEIGHT LEVEL

Excess weight, especially obesity, negatively impacts brain health by reducing brain volume, impairing cognitive functions like memory and executive skills, and increasing dementia risk, potentially due to inflammation and metabolic changes; however, modest weight loss through diet, exercise, or medication can improve brain function, with strength training also shown to boost brain health by improving blood flow and reducing inflammation.

How excess weight harms the brain

Reduced brain tissue: Obesity is linked to less brain tissue, including grey matter atrophy, which affects cognitive performance.

Impaired cognitive function: Higher BMI is associated with poorer attention, slower processing speed, weaker working memory, and issues with decision-making and planning.

Decreased brain activity: Weight gain can lead to reduced blood flow and activity in all brain regions, including those vulnerable to Alzheimer’s.

Accelerated aging: Compromised white matter integrity in overweight individuals suggests accelerated brain aging.

Increased dementia risk: Middle-aged obesity significantly raises the risk of developing dementia later in life.

How weight management helps the brain

Modest weight loss: Losing just 5-10% of body weight can improve blood pressure, blood sugar, and inflammation, benefiting brain health.

Improved function: Even small weight reductions can boost daily brain performance, memory, and learning.

Better structure: Weight loss after bariatric surgery has been shown to improve brain health.
