A pilot study that suggests intermittent fasting could be a tool to use to help improve cognitive function in older peopleAn elderly woman with Dementia and Alzheimer's Disease sitting in her home eating a meal looking confused and worried. Lifestyle factors are just one possible factor that may increase risk of cognitive decline in older age, so I was interested to read about a pilot study that suggests intermittent fasting could be a tool to use to help improve cognitive function in older people. There are a few possible reasons why intermittent fasting has such a positive impact on brain health. Intermittent fasting has lots of benefits apart from just cutting calories. Restricting our eating window can help reduce inflammation, support a better blood sugar/insulin response and promotes metabolic health.
