A large-scale study from the University of Exeter has found ‘robust evidence’ that being overweight hikes up your risk of developing depression – but as fresh evidence confirms, logging your morning miles is one of the most effective ways to fight back. Exercise jolts your brain into action, and not just because of the endorphin high … ‘Obesity and depression are both major global health challenges, and our study provides the most robust evidence to date that higher BMI causes depression,’ said lead author Jess O’Loughlin. ‘Understanding whether physical or social factors are responsible for this relationship can help inform effective strategies to improve mental health and wellbeing.’ [Read more…] about Studies find growing evidence linking weight, physical activity, neuroplasticity and depression
body mass index
Body weight has surprising, alarming impact on brain function (Science Daily):
As a person’s weight goes up, all regions of the brain go down in activity and blood flow, according to a new brain imaging study in the Journal of Alzheimer’s Disease … scientists analyzed over 35,000 functional neuroimaging scans using single-photon emission computerized tomography (SPECT) from more than 17,000 individuals to measure blood flow and brain activity.

Although there’s still no cure, researchers are continuing to develop a better understanding of what increases a person’s risk of developing Alzheimer’s disease. A recent study that looked at 396 studies has even been able to identify ten risk factors that are shown to increase the likelihood of developing the disease.
Here are the factors researchers identified – and why they’re associated with a higher risk.
1. Lower education level
A lower education level is associated with an increased risk of Alzheimer’s disease. Previous evidence shows the longer you spend in education, the lower your risk of developing dementia. Research looking at the brains of people from different educational backgrounds also showed that people who were more educated had heavier brains. As you lose one third of your brain weight because of dementia, a heavier brain may make you more resilient.
