Despite decades of efforts to develop a drug that prevents or cures Alzheimer’s disease (AD), the most prevalent form of dementia afflicting our aging population, there is currently no treatment for this devastating condition. Emerging research suggests that such a miracle treatment might already exist, not in the form of a pill, but as a simple dietary change. A growing number of studies report that interventions to improve metabolic health can alleviate symptoms and reduce brain pathology associated with AD. A popular theory posits that AD has multiple causes, but their common thread may involve metabolic dysfunction. Indeed, markers of poor metabolic health, such as diabetes, inflammation and high cholesterol, are major risk factors for AD.
Just like our muscles, the brain requires energy to function properly. Both neurons and muscles have the unique capacity to metabolize ketones as an alternative fuel source when glucose is
