Dementia is a chronic degenerative disease that impairs cognitive abilities such as memory, language, and perception.
According to research studies, approximately 50 million people worldwide live with dementia, and this number is expected to triple by 2050.
While there is no cure for dementia, several lifestyle modifications can help prevent or delay the onset of this disease. One such modification is maintaining a healthy weight.
The science behind weight and dementia risk
Recent research has shown that being overweight or obese is linked to an increased risk of several chronic diseases, including dementia.
A study conducted in 2020 in the UK found that being overweight or obese has a direct correlation with an individual’s risk of developing dementia.
A possible explanation behind this link is that excess body fat could lead to the accumulation of harmful toxins and molecules that negatively affect cognitive function.
Additionally, carrying extra weight can cause inflammation and damage to blood vessels that can also contribute to dementia.

Check your dementia risk
If you are overweight or obese, how can you determine your risk of developing dementia? One way is by calculating your body mass index (BMI).
BMI is a measure of body fat based on your height and weight. Calculate your BMI by dividing your weight in kilograms by the square of your height in meters.
Once you determine your BMI, use the table below to determine your risk level for dementia based on your weight category.
| Weight category | BMI range | Dementia risk |
|---|---|---|
| Underweight | Less than 18.5 | Moderate |
| Normal weight | 18.5 to 24.9 | Low |
| Overweight | 25.0 to 29.9 | Moderate |
| Obese | 30 or higher | High |
Other lifestyle modifications to reduce dementia risk
Maintaining a healthy weight is just one of the several lifestyle modifications that can help prevent dementia.
Other modifications include regular physical activity, healthy dietary choices, avoiding tobacco and excessive alcohol, staying socially engaged, getting enough sleep, and staying mentally active.
Conclusion
In conclusion, being overweight or obese is linked to an increased risk of dementia. However, through lifestyle modifications, including maintaining a healthy weight, individuals can help reduce their risk of developing this chronic disease.
