Certified Ketogenic Nutrition Specialist


Who is Mary T Newport MD?

Mary T. Newport, M.D. became a messenger in 2008 when she found a nutritional intervention that supplied ketones as alternative fuel for the brain for her husband Steve Newport with early-onset Alzheimer’s disease. Steve responded dramatically to consuming medium-chain triglycerides (MCTs) from coconut oil which produce ketones when consumed. Two years later he improved again in a pilot study of one person consuming the Veech ketone ester…this ester added twenty more months of stability. Together these solutions gave him nearly four more better-quality years.

Dr. Newport grew up in Cincinnati, Ohio, attended Xavier University for pre-medicine, and graduated from the University of Cincinnati College of Medicine in 1978. She trained in Pediatrics at Children’s Hospital Medical Center in Cincinnati and completed her fellowship in neonatology, the care of sick and premature newborns, at the Medical University Hospital in Charleston, SC. She practiced neonatology in Florida for 30 years and served as founding medical director for two newborn intensive care units in the Tampa Bay area. After taking some time off to care for Steve, she resumed medical practice at the opposite end of the spectrum and now makes home visits with people who have chronic conditions. Dr. Newport was married to Steve Newport in 1972 and they have two daughters and a grandson.  Steve lost his battle with Alzheimer’s and Lewy body dementia in 2016.  To carry on his legacy, she remains a fervent messenger for ketones as an alternative fuel for the brain for Alzheimer’s and other disorders.  She is author of four books and an international speaker on the subject of ketones as an alternative fuel for the brain, with numerous speaking engagements throughout the USA, Canada, Mexico, Australia and many countries in Europe and Asia. 

Dr. Newport is a Certified Ketogenic Nutrition Specialist (CKNS) since September 2019 through a program offered by the American Nutrition Association.
